v38.1.0

#1208: Improve error message when failing to locate scripts in egg-info metadata.

v38.0.0

#458: In order to support deterministic builds, Setuptools no longer allows packages to declare install_requires as unordered sequences (sets or dicts).

v37.0.0

#878: Drop support for Python 2.6. Python 2.6 users should rely on 'setuptools < 37dev'.

v36.8.0

#1143: Added dist_info command for producing dist_info metadata.

v36.5.0

#170: When working with Mercurial checkouts, use Windows-friendly syntax for suppressing output.
Inspired by #1134, performed substantial refactoring of pkg_resources.find_on_path to facilitate an optimization for paths with many non-version entries.

#1133: Improved handling of README files extensions and added Markdown to the list of searched READMES.
#1135: Improve performance of pkg_resources import by not invoking access or stat and using os.listdir instead.

v36.3.0

#1131: Make possible using several files within file: directive in metadata.long_description in setup.cfg.

v36.2.7

v36.2.3

#1102: Restore behavior for empty extras.

v36.2.2

#1099: Revert commit a3ec721, restoring intended purpose of extras as part of a requirement declaration.

v36.2.1

fix #1086
fix #1087
support extras specifiers in install_requires requirements

v36.2.0

#1081: Environment markers indicated in install_requires are now processed and treated as nameless extras_require with markers, allowing their metadata in requires.txt to be correctly generated.
#1053: Tagged commits are now released using Travis-CI build stages, meaning releases depend on passing tests on all supported Python versions (Linux) and not just the latest Python version.

v36.1.1

#1083: Correct py31compat.makedirs to correctly honor exist_ok parameter.
#1083: Also use makedirs compatibility throughout setuptools.

v36.1.0

#1083: Avoid race condition on directory creation in pkg_resources.ensure_directory.
Removed deprecation of and restored support for upload_docs command for sites other than PyPI. Only warehouse is dropping support, but services like devpi continue to support docs built by setuptools' plugins. See this comment for more context on the motivation for this change.

v36.0.1

#1042: Fix import in py27compat module that still referenced six directly, rather than through the externs module (vendored packages hook).

v36.0.0

#980 and others: Once again, Setuptools vendors all of its dependencies. It seems to be the case that in the Python ecosystem, all build tools must run without any dependencies (build, runtime, or otherwise). At such a point that a mechanism exists that allows build tools to have dependencies, Setuptools will adopt it.

v35.0.2

#1015: Fix test failures on Python 3.7.
#1024: Add workaround for Jython #2581 in monkey module.

v35.0.1

#992: Revert change introduced in v34.4.1, now considered invalid.
#1016: Revert change introduced in v35.0.0 per #1014, referencing #436. The approach had unintended consequences, causing sdist installs to be missing files.

v35.0.0

#436: In egg_info.manifest_maker, no longer read the file list from the manifest file, and instead re-build it on each build. In this way, files removed from the specification will not linger in the manifest. As a result, any files manually added to the manifest will be removed on subsequent egg_info invocations. No projects should be manually adding files to the manifest and should instead use MANIFEST.in or SCM file finders to force inclusion of files in the manifest.

v34.4.1

#1008: In MSVC support, use always the last version available for Windows SDK and UCRT SDK.
#1008: In MSVC support, fix "vcruntime140.dll" returned path with Visual Studio 2017.
#992: In msvc.msvc9_query_vcvarsall, ensure the returned dicts have str values and not Unicode for compatibility with os.environ.

v34.4.0

#995: In MSVC support, add support for "Microsoft Visual Studio 2017" and "Microsoft Visual Studio Build Tools 2017".
#999 via #1007: Extend support for declarative package config in a setup.cfg file to include the options python_requires and py_modules.

v34.3.3

#967 (and #997): Explicitly import submodules of packaging to account for environments where the imports of those submodules is not implied by other behavior.

v34.3.2

#993: Fix documentation upload by correcting rendering of content-type in _build_multipart on Python 3.

v34.3.1

#988: Trap os.unlink same as os.remove in auto_chmod error handler.
#983: Fixes to invalid escape sequence deprecations on Python 3.6.

v34.3.0

#941: In the upload command, if the username is blank, default to getpass.getuser().
#971: Correct distutils findall monkeypatch to match appropriate versions (namely Python 3.4.6).

v34.2.0

#966: Add support for reading dist-info metadata and thus locating Distributions from zip files.
#968: Allow '+' and '!' in egg fragments so that it can take package names that contain PEP 440 conforming version specifiers.

v34.1.1

#953: More aggressively employ the compatibility issue originally added in #706.

v34.1.0

#930: build_info now accepts two new parameters to optimize and customize the building of C libraries.

v34.0.3

#947: Loosen restriction on the version of six required, restoring compatibility with environments relying on six 1.6.0 and later.

v34.0.2

#882: Ensure extras are honored when building the working set.
#913: Fix issue in develop if package directory has a trailing slash.

v34.0.1

#935: Fix glob syntax in graft.

v34.0.0

#581: Instead of vendoring the growing list of dependencies that Setuptools requires to function, Setuptools now requires these dependencies just like any other project. Unlike other projects, however, Setuptools cannot rely on setup_requires to demand the dependencies it needs to install because its own machinery would be necessary to pull those dependencies if not present (a bootstrapping problem). As a result, Setuptools no longer supports self upgrade or installation in the general case. Instead, users are directed to use pip to install and upgrade using the wheel distributions of setuptools.

Users are welcome to contrive other means to install or upgrade Setuptools using other means, such as pre-installing the Setuptools dependencies with pip or a bespoke bootstrap tool, but such usage is not recommended and is not supported.

As discovered in #940, not all versions of pip will successfully install Setuptools from its pre-built wheel. If you encounter issues with "No module named six" or "No module named packaging", especially following a line "Running setup.py egg_info for package setuptools", then your pip is not new enough.

There's an additional issue in pip where setuptools is upgraded concurrently with other source packages, described in pip #4253. The proposed workaround is to always upgrade Setuptools first prior to upgrading other packages that would upgrade Setuptools.

v33.1.1

#921: Correct issue where certifi fallback not being reached on Windows.

v33.1.0

Installation via pip, as indicated in the Python Packaging User's Guide, is the officially-supported mechanism for installing Setuptools, and this recommendation is now explicit in the much more concise README.

Other edits and tweaks were made to the documentation. The codebase is unchanged.

v33.0.0

#619: Removed support for the tag_svn_revision distribution option. If Subversion tagging support is still desired, consider adding the functionality to setuptools_svn in setuptools_svn #2.

v32.3.1

#866: Use dis.Bytecode on Python 3.4 and later in setuptools.depends.

v32.3.0

#889: Backport proposed fix for disabling interpolation in distutils.Distribution.parse_config_files.

v32.2.0

#884: Restore support for running the tests under pytest-runner by ensuring that PYTHONPATH is honored in tests invoking a subprocess.

v32.1.3

#706: Add rmtree compatibility shim for environments where rmtree fails when passed a unicode string.

v32.1.2

#893: Only release sdist in zip format as warehouse now disallows releasing two different formats.

v32.1.1

#704: More selectively ensure that 'rmtree' is not invoked with a byte string, enabling it to remove files that are non-ascii, even on Python 2.
#712: In 'sandbox.run_setup', ensure that __file__ is always a str, modeling the behavior observed by the interpreter when invoking scripts and modules.

v32.1.0

#891: In 'test' command on test failure, raise DistutilsError, suppression invocation of subsequent commands.

v32.0.0

#890: Revert #849. global-exclude .foo will not match all *.foo files any more. Package authors must add an explicit wildcard, such as global-exclude *.foo, to match all .foo files. See #886, #849.

v31.0.1

#885: Fix regression where 'pkg_resources._rebuild_mod_path' would fail when a namespace package's '__path__' was not a list with a sort attribute.

v31.0.0

#250: Install '-nspkg.pth' files for packages installed with 'setup.py develop'. These .pth files allow namespace packages installed by pip or develop to co-mingle. This change required the removal of the change for #805 and pip #1924, introduced in 28.3.0 and implicated in #870, but means that namespace packages not in a site packages directory will no longer work on Python earlier than 3.5, whereas before they would work on Python not earlier than 3.3.

v30.4.0

#879: For declarative config:
- read_configuration() now accepts ignore_option_errors argument. This allows scraping tools to read metadata without a need to download entire packages. E.g. we can gather some stats right from GitHub repos just by downloading setup.cfg.
- packages find: directive now supports fine tuning from a subsection. The same arguments as for find() are accepted.

v30.3.0

#394 via #862: Added support for declarative package config in a setup.cfg file.

v30.2.1

#850: In test command, invoke unittest.main with indication not to exit the process.

v30.2.0

#854: Bump to vendored Packaging 16.8.

v30.1.0

#846: Also trap 'socket.error' when opening URLs in package_index.
#849: Manifest processing now matches the filename pattern anywhere in the filename and not just at the start. Restores behavior found prior to 28.5.0.

v30.0.0

#864: Drop support for Python 3.2. Systems requiring Python 3.2 support must use 'setuptools < 30'.
#825: Suppress warnings for single files.
#830 via #843: Once again restored inclusion of data files to sdists, but now trap TypeError caused by techniques employed rjsmin and similar.

v29.0.1

#861: Re-release of v29.0.1 with the executable script launchers bundled. Now, launchers are included by default and users that want to disable this behavior must set the environment variable 'SETUPTOOLS_INSTALL_WINDOWS_SPECIFIC_FILES' to a false value like "false" or "0".

v29.0.0

#841: Drop special exception for packages invoking win32com during the build/install process. See Distribute #118 for history.

v28.8.0

#629: Per the discussion, refine the sorting to use version value order for more accurate detection of the latest available version when scanning for packages. See also #829.
#837: Rely on the config var "SO" for Python 3.3.0 only when determining the ext filename.

v28.7.1

#827: Update PyPI root for dependency links.
#833: Backed out changes from #830 as the implementation seems to have problems in some cases.

v28.7.0

#832: Moved much of the namespace package handling functionality into a separate module for re-use in something like #789.
#830: sdist command no longer suppresses the inclusion of data files, re-aligning with the expectation of distutils and addressing #274 and #521.

v28.6.1

#816: Fix manifest file list order in tests.

v28.6.0

#629: When scanning for packages, pkg_resources now ignores empty egg-info directories and gives precedence to packages whose versions are lexicographically greatest, a rough approximation for preferring the latest available version.

v28.5.0

#810: Tests are now invoked with tox and not setup.py test.
#249 and #450 via #764: Avoid scanning the whole tree when building the manifest. Also fixes a long-standing bug where patterns in MANIFEST.in had implicit wildcard matching. This caused global-exclude .foo to exclude all *.foo files, but also global-exclude bar.py to exclude foo_bar.py.

v28.4.0

#732: Now extras with a hyphen are honored per PEP 426.
#811: Update to pyparsing 2.1.10.
Updated setuptools.command.sdist to re-use most of the functionality directly from distutils.command.sdist for the add_defaults method with strategic overrides. See #750 for rationale.
#760 via #762: Look for certificate bundle where SUSE Linux typically presents it. Use certifi.where() to locate the bundle.

v28.3.0

#809: In find_packages(), restore support for excluding a parent package without excluding a child package.
#805: Disable -nspkg.pth behavior on Python 3.3+ where PEP-420 functionality is adequate. Fixes pip #1924.

v28.1.0

#803: Bump certifi to 2016.9.26.

v28.0.0

#733: Do not search excluded directories for packages. This introduced a backwards incompatible change in find_packages() so that find_packages(exclude=['foo']) == [], excluding subpackages of foo. Previously, find_packages(exclude=['foo']) == ['foo.bar'], even though the parent foo package was excluded.
#795: Bump certifi.
#719: Suppress decoding errors and instead log a warning when metadata cannot be decoded.

v27.3.1

#790: In MSVC monkeypatching, explicitly patch each function by name in the target module instead of inferring the module from the function's __module__. Improves compatibility with other packages that might have previously patched distutils functions (i.e. NumPy).

v27.3.0

#794: In test command, add installed eggs to PYTHONPATH when invoking tests so that subprocesses will also have the dependencies available. Fixes tox 330.
#795: Update vendored pyparsing 2.1.9.

v27.2.0

#520 and #513: Suppress ValueErrors in fixup_namespace_packages when lookup fails.
Nicer, more consistent interfaces for msvc monkeypatching.

v27.1.2

#779 via #781: Fix circular import.

v27.1.1

#778: Fix MSVC monkeypatching.

v27.1.0

Introduce the (private) monkey module to encapsulate the distutils monkeypatching behavior.

v27.0.0

Now use Warehouse by default for upload, patching distutils.config.PyPIRCCommand to affect default behavior.

Any config in .pypirc should be updated to replace

https://pypi.python.org/pypi/

with

https://upload.pypi.org/legacy/

Similarly, any passwords stored in the keyring should be updated to use this new value for "system".

The upload_docs command will continue to use the python.org site, but the command is now deprecated. Users are urged to use Read The Docs instead.
#776: Use EXT_SUFFIX for py_limited_api renaming.
#774 and #775: Use LegacyVersion from packaging when detecting numpy versions.

v26.1.1

Re-release of 26.1.0 with pytest pinned to allow for automated deployment and thus proper packaging environment variables, fixing issues with missing executable launchers.

v26.1.0

#763: pkg_resources.get_default_cache now defers to the appdirs project to resolve the cache directory. Adds a vendored dependency on appdirs to pkg_resources.

v26.0.0

#748: By default, sdists are now produced in gzipped tarfile format by default on all platforms, adding forward compatibility for the same behavior in Python 3.6 (See Python #27819).
#459 via #736: On Windows with script launchers, sys.argv[0] now reflects the name of the entry point, consistent with the behavior in distlib and pip wrappers.
#752 via #753: When indicating py_limited_api to Extension, it must be passed as a keyword argument.

v25.4.0

Add Extension(py_limited_api=True). When set to a truthy value, that extension gets a filename appropriate for code using Py_LIMITED_API. When used correctly this allows a single compiled extension to work on all future versions of CPython 3. The py_limited_api argument only controls the filename. To be compatible with multiple versions of Python 3, the C extension will also need to set -DPy_LIMITED_API=... and be modified to use only the functions in the limited API.

v25.3.0

#739 Fix unquoted libpaths by fixing compatibility between numpy.distutils and distutils._msvccompiler for numpy < 1.11.2 (Fix issue #728, error also fixed in Numpy).
#731: Bump certifi.
Style updates. See #740, #741, #743, #744, #742, #747.
#735: include license file.

v25.2.0

#612 via #730: Add a LICENSE file which needs to be provided by the terms of the MIT license.

v25.1.6

#725: revert library_dir_option patch (Error is related to numpy.distutils and make errors on non Numpy users).

v25.1.5

#720
#723: Improve patch for library_dir_option.

v25.1.4

#717
#713
#707: Fix Python 2 compatibility for MSVC by catching errors properly.
#715: Fix unquoted libpaths by patching library_dir_option.

v25.1.3

#714 and #704: Revert fix as it breaks other components downstream that can't handle unicode. See #709, #710, and #712.

v25.1.2

#704: Fix errors when installing a zip sdist that contained files named with non-ascii characters on Windows would crash the install when it attempted to clean up the build.
#646: MSVC compatibility - catch errors properly in RegistryInfo.lookup.
#702: Prevent UnboundLocalError when initial working_set is empty.

v25.1.1

#686: Fix issue in sys.path ordering by pkg_resources when rewrite technique is "raw".
#699: Fix typo in msvc support.

v25.1.0

#609: Setuptools will now try to download a distribution from the next possible download location if the first download fails. This means you can now specify multiple links as dependency_links and all links will be tried until a working download link is encountered.

v25.0.2

#688: Fix AttributeError in setup.py when invoked not from the current directory.

v25.0.1

Cleanup of setup.py script.
Fixed documentation builders by allowing setup.py to be imported without having bootstrapped the metadata.
More style cleanup. See #677, #678, #679, #681, #685.

v25.0.0

#674: Default sys.path manipulation by easy-install.pth is now "raw", meaning that when writing easy-install.pth during any install operation, the sys.path will not be rewritten and will no longer give preference to easy_installed packages.

To retain the old behavior when using any easy_install operation (including setup.py install when setuptools is present), set the environment variable:

SETUPTOOLS_SYS_PATH_TECHNIQUE=rewrite

This project hopes that that few if any environments find it necessary to retain the old behavior, and intends to drop support for it altogether in a future release. Please report any relevant concerns in the ticket for this change.

v24.3.1

#398: Fix shebang handling on Windows in script headers where spaces in sys.executable would produce an improperly-formatted shebang header, introduced in 12.0 with the fix for #188.
#663, #670: More style updates.

v24.3.0

#516: Disable os.link to avoid hard linking in sdist.make_distribution, avoiding errors on systems that support hard links but not on the file system in which the build is occurring.

v24.2.1

#667: Update Metadata-Version to 1.2 when python_requires is supplied.

v24.2.0

#631: Add support for python_requires keyword.

v24.1.1

More style updates. See #660, #661, #641.

v24.1.0

#659: setup.py now will fail fast and with a helpful error message when the necessary metadata is missing.
More style updates. See #656, #635, #640, #644, #650, #652, and #655.

v24.0.3

Updated style in much of the codebase to match community expectations. See #632, #633, #634, #637, #639, #638, #642, #648.

v24.0.2

If MSVC++14 is needed setuptools.msvc now redirect user to Visual C++ Build Tools web page.

v24.0.1

#625 and #626: Fixes on setuptools.msvc mainly for Python 2 and Linux.

v24.0.0

Pull Request #174: Add more aggressive support for standalone Microsoft Visual C++ compilers in msvc9compiler patch. Particularly : Windows SDK 6.1 and 7.0 (MSVC++ 9.0), Windows SDK 7.1 (MSVC++ 10.0), Visual C++ Build Tools 2015 (MSVC++14)
Renamed setuptools.msvc9_support to setuptools.msvc.

v23.2.1

Re-release of v23.2.0, which was missing the intended commits.

#623: Remove used of deprecated 'U' flag when reading manifests.

v23.1.0

#619: Deprecated tag_svn_revision distribution option.

v23.0.0

#611: Removed ARM executables for CLI and GUI script launchers on Windows. If this was a feature you cared about, please comment in the ticket.
#604: Removed docs building support. The project now relies on documentation hosted at https://setuptools.readthedocs.io/.

v22.0.5

#604: Restore repository for upload_docs command to restore publishing of docs during release.

v22.0.4

#589: Upload releases to pypi.io using the upload hostname and legacy path.

v22.0.3

#589: Releases are now uploaded to pypi.io (Warehouse) even when releases are made on Twine via Travis.

v22.0.2

#589: Releases are now uploaded to pypi.io (Warehouse).

v22.0.1

#190: On Python 2, if unicode is passed for packages to build_py command, it will be handled just as with text on Python 3.

v22.0.0

Intended to be v21.3.0, but jaraco accidentally released as a major bump.

#598: Setuptools now lists itself first in the User-Agent for web requests, better following the guidelines in RFC 7231.

v21.2.2

Minor fixes to changelog and docs.

v21.2.1

#261: Exclude directories when resolving globs in package_data.

v21.2.0

#539: In the easy_install get_site_dirs, honor all paths found in site.getsitepackages.

v21.1.0

#572: In build_ext, now always import _CONFIG_VARS from distutils rather than from sysconfig to allow distutils.sysconfig.customize_compiler configure the OS X compiler for -dynamiclib.

v21.0.0

Removed ez_setup.py from Setuptools sdist. The bootstrap script will be maintained in its own branch and should be generally be retrieved from its canonical location at https://bootstrap.pypa.io/ez_setup.py.

v20.10.0

#553: egg_info section is now generated in a deterministic order, matching the order generated by earlier versions of Python. Except on Python 2.6, order is preserved when existing settings are present.
#556: Update to Packaging 16.7, restoring support for deprecated python_implmentation marker.
#555: Upload command now prompts for a password when uploading to PyPI (or other repository) if no password is present in .pypirc or in the keyring.

v20.9.0

#548: Update certify version to 2016.2.28
#545: Safely handle deletion of non-zip eggs in rotate command.

v20.8.1

Issue #544: Fix issue with extra environment marker processing in WorkingSet due to refactor in v20.7.0.

v20.8.0

Issue #543: Re-release so that latest release doesn't cause déjà vu with distribute and setuptools 0.7 in older environments.

v20.7.0

Refactored extra environment marker processing in WorkingSet.
Issue #533: Fixed intermittent test failures.
Issue #536: In msvc9_support, trap additional exceptions that might occur when importing distutils.msvc9compiler in mingw environments.
Issue #537: Provide better context when package metadata fails to decode in UTF-8.

v20.6.8

Issue #523: Restored support for environment markers, now honoring 'extra' environment markers.

v20.6.7

Issue #523: Disabled support for environment markers introduced in v20.5.

v20.6.6

Issue #503: Restore support for PEP 345 environment markers by updating to Packaging 16.6.

v20.6.0

New release process that relies on bumpversion and Travis CI for continuous deployment.
Project versioning semantics now follow semver precisely. The 'v' prefix on version numbers now also allows version numbers to be referenced in the changelog, e.g. http://setuptools.readthedocs.io/en/latest/history.html#v20-6-0.

20.5

BB Pull Request #185, #470: Add support for environment markers in requirements in install_requires, setup_requires, tests_require as well as adding a test for the existing extra_requires machinery.

20.4

Issue #422: Moved hosting to Github from Bitbucket. Issues have been migrated, though all issues and comments are attributed to bb-migration. So if you have a particular issue or issues to which you've been subscribed, you will want to "watch" the equivalent issue in Github. The Bitbucket project will be retained for the indefinite future, but Github now hosts the canonical project repository.

20.3.1

Issue #519: Remove import hook when reloading the pkg_resources module.
BB Pull Request #184: Update documentation in pkg_resources around new Requirement implementation.

20.3

BB Pull Request #179: pkg_resources.Requirement objects are now a subclass of packaging.requirements.Requirement, allowing any environment markers and url (if any) to be affiliated with the requirement
BB Pull Request #179: Restore use of RequirementParseError exception unintentionally dropped in 20.2.

20.2.2

Issue #502: Correct regression in parsing of multiple version specifiers separated by commas and spaces.

20.2.1

Issue #499: Restore compatibility for legacy versions by bumping to packaging 16.4.

20.2

Changelog now includes release dates and links to PEPs.
BB Pull Request #173: Replace dual PEP 345 _markerlib implementation and PEP 426 implementation of environment marker support from packaging 16.1 and PEP 508. Fixes Issue #122. See also BB Pull Request #175, BB Pull Request #168, and BB Pull Request #164. Additionally:
- Requirement.parse no longer retains the order of extras.
- parse_requirements now requires that all versions be PEP-440 compliant, as revealed in #499. Packages released with invalid local versions should be re-released using the proper local version syntax, e.g. mypkg-1.0+myorg.1.

20.1.1

Update upload_docs command to also honor keyring for password resolution.

20.1

Added support for using passwords from keyring in the upload command. See the upload docs for details.

20.0

Issue #118: Once again omit the package metadata (egg-info) from the list of outputs in --record. This version of setuptools can no longer be used to upgrade pip earlier than 6.0.

19.7

Off-project PR: For FreeBSD, also honor root certificates from ca_root_nss.

19.6.2

Issue #491: Correct regression incurred in 19.4 where a double-namespace package installed using pip would cause a TypeError.

19.6.1

Restore compatibility for PyPy 3 compatibility lost in 19.4.1 addressing Issue #487.
setuptools.launch shim now loads scripts in a new namespace, avoiding getting relative imports from the setuptools package on Python 2.

19.6

Added a new entry script setuptools.launch, implementing the shim found in pip.util.setuptools_build. Use this command to launch distutils-only packages under setuptools in the same way that pip does, causing the setuptools monkeypatching of distutils to be invoked prior to invoking a script. Useful for debugging or otherwise installing a distutils-only package under setuptools when pip isn't available or otherwise does not expose the desired functionality. For example:
```
$ python -m setuptools.launch setup.py develop
```
Issue #488: Fix dual manifestation of Extension class in extension packages installed as dependencies when Cython is present.

19.5

Issue #486: Correct TypeError when getfilesystemencoding returns None.
Issue #139: Clarified the license as MIT.
BB Pull Request #169: Removed special handling of command spec in scripts for Jython.

19.4.1

Issue #487: Use direct invocation of importlib.machinery in pkg_resources to avoid missing detection on relevant platforms.

19.4

Issue #341: Correct error in path handling of package data files in build_py command when package is empty.
Distribute #323, Issue #141, Issue #207, and BB Pull Request #167: Another implementation of pkg_resources.WorkingSet and pkg_resources.Distribution that supports replacing an extant package with a new one, allowing for setup_requires dependencies to supersede installed packages for the session.

19.3

Issue #229: Implement new technique for readily incorporating dependencies conditionally from vendored copies or primary locations. Adds a new dependency on six.

19.2

BB Pull Request #163: Add get_command_list method to Distribution.
BB Pull Request #162: Add missing whitespace to multiline string literals.

19.1.1

Issue #476: Cast version to string (using default encoding) to avoid creating Unicode types on Python 2 clients.
Issue #477: In Powershell downloader, use explicit rendering of strings, rather than rely on repr, which can be incorrect (especially on Python 2).

19.1

Issue #215: The bootstrap script ez_setup.py now automatically detects the latest version of setuptools (using PyPI JSON API) rather than hard-coding a particular value.
Issue #475: Fix incorrect usage in _translate_metadata2.

19.0

Issue #442: Use RawConfigParser for parsing .pypirc file. Interpolated values are no longer honored in .pypirc files.

18.8.1

Issue #440: Prevent infinite recursion when a SandboxViolation or other UnpickleableException occurs in a sandbox context with setuptools hidden. Fixes regression introduced in Setuptools 12.0.

18.8

Deprecated egg_info.get_pkg_info_revision.
Issue #471: Don't rely on repr for an HTML attribute value in package_index.
Issue #419: Avoid errors in FileMetadata when the metadata directory is broken.
Issue #472: Remove deprecated use of 'U' in mode parameter when opening files.

18.7.1

Issue #469: Refactored logic for Issue #419 fix to re-use metadata loading from Provider.

18.7

Update dependency on certify.
BB Pull Request #160: Improve detection of gui script in easy_install._adjust_header.
Made test.test_args a non-data property; alternate fix for the issue reported in BB Pull Request #155.
Issue #453: In ez_setup bootstrap module, unload all pkg_resources modules following download.
BB Pull Request #158: Honor PEP-488 when excluding files for namespace packages.
Issue #419 and BB Pull Request #144: Add experimental support for reading the version info from distutils-installed metadata rather than using the version in the filename.

18.6.1

Issue #464: Correct regression in invocation of superclass on old-style class on Python 2.

18.6

Issue #439: When installing entry_point scripts under development, omit the version number of the package, allowing any version of the package to be used.

18.5

In preparation for dropping support for Python 3.2, a warning is now logged when pkg_resources is imported on Python 3.2 or earlier Python 3 versions.
Add support for python_platform_implementation environment marker.
Fix dictionary mutation during iteration.

18.4

Issue #446: Test command now always invokes unittest, even if no test suite is supplied.

18.3.2

Correct another regression in setuptools.findall where the fix for Python #12885 was lost.

18.3.1

Issue #425: Correct regression in setuptools.findall.

18.3

BB Pull Request #135: Setuptools now allows disabling of the manipulation of the sys.path during the processing of the easy-install.pth file. To do so, set the environment variable SETUPTOOLS_SYS_PATH_TECHNIQUE to anything but "rewrite" (consider "raw"). During any install operation with manipulation disabled, setuptools packages will be appended to sys.path naturally.

Future versions may change the default behavior to disable manipulation. If so, the default behavior can be retained by setting the variable to "rewrite".
Issue #257: easy_install --version now shows more detail about the installation location and Python version.
Refactor setuptools.findall in preparation for re-submission back to distutils.

18.2

Issue #412: More efficient directory search in find_packages.

18.1

Upgrade to vendored packaging 15.3.

18.0.1

Issue #401: Fix failure in test suite.

18.0

Dropped support for builds with Pyrex. Only Cython is supported.
Issue #288: Detect Cython later in the build process, after setup_requires dependencies are resolved. Projects backed by Cython can now be readily built with a setup_requires dependency. For example:
```
ext = setuptools.Extension('mylib', ['src/CythonStuff.pyx', 'src/CStuff.c'])
setuptools.setup(
    ...
    ext_modules=[ext],
    setup_requires=['cython'],
)
```
For compatibility with older versions of setuptools, packagers should still include src/CythonMod.c in the source distributions or require that Cython be present before building source distributions. However, for systems with this build of setuptools, Cython will be downloaded on demand.
Issue #396: Fixed test failure on OS X.
BB Pull Request #136: Remove excessive quoting from shebang headers for Jython.

17.1.1

Backed out unintended changes to pkg_resources, restoring removal of deprecated imp module (ref).

17.1

Issue #380: Add support for range operators on environment marker evaluation.

17.0

Issue #378: Do not use internal importlib._bootstrap module.
Issue #390: Disallow console scripts with path separators in the name. Removes unintended functionality and brings behavior into parity with pip.

16.0

BB Pull Request #130: Better error messages for errors in parsed requirements.
BB Pull Request #133: Removed setuptools.tests from the installed packages.
BB Pull Request #129: Address deprecation warning due to usage of imp module.

15.2

Issue #373: Provisionally expose pkg_resources._initialize_master_working_set, allowing for imperative re-initialization of the master working set.

15.1

Updated to Packaging 15.1 to address Packaging #28.
Fix setuptools.sandbox._execfile() with Python 3.1.

15.0

BB Pull Request #126: DistributionNotFound message now lists the package or packages that required it. E.g.:
```
pkg_resources.DistributionNotFound: The 'colorama>=0.3.1' distribution was not found and is required by smlib.log.
```
Note that zc.buildout once dependended on the string rendering of this message to determine the package that was not found. This expectation has since been changed, but older versions of buildout may experience problems. See Buildout #242 for details.

14.3.1

Issue #307: Removed PEP-440 warning during parsing of versions in pkg_resources.Distribution.
Issue #364: Replace deprecated usage with recommended usage of EntryPoint.load.

14.3

Issue #254: When creating temporary egg cache on Unix, use mode 755 for creating the directory to avoid the subsequent warning if the directory is group writable.

14.2

Issue #137: Update Distribution.hashcmp so that Distributions with None for pyversion or platform can be compared against Distributions defining those attributes.

14.1.1

Issue #360: Removed undesirable behavior from test runs, preventing write tests and installation to system site packages.

14.1

BB Pull Request #125: Add __ne__ to Requirement class.
Various refactoring of easy_install.

14.0

Bootstrap script now accepts --to-dir to customize save directory or allow for re-use of existing repository of setuptools versions. See BB Pull Request #112 for background.
Issue #285: easy_install no longer will default to installing packages to the "user site packages" directory if it is itself installed there. Instead, the user must pass --user in all cases to install packages to the user site packages. This behavior now matches that of "pip install". To configure an environment to always install to the user site packages, consider using the "install-dir" and "scripts-dir" parameters to easy_install through an appropriate distutils config file.

13.0.2

Issue #359: Include pytest.ini in the sdist so invocation of py.test on the sdist honors the pytest configuration.

13.0.1

Re-release of 13.0. Intermittent connectivity issues caused the release process to fail and PyPI uploads no longer accept files for 13.0.

13.0

Issue #356: Back out BB Pull Request #119 as it requires Setuptools 10 or later as the source during an upgrade.
Removed build_py class from setup.py. According to 892f439d216e, this functionality was added to support upgrades from old Distribute versions, 0.6.5 and 0.6.6.

12.4

BB Pull Request #119: Restore writing of setup_requires to metadata (previously added in 8.4 and removed in 9.0).

12.3

Documentation is now linked using the rst.linker package.
Fix setuptools.command.easy_install.extract_wininst_cfg() with Python 2.6 and 2.7.
Issue #354. Added documentation on building setuptools documentation.

12.2

Issue #345: Unload all modules under pkg_resources during ez_setup.use_setuptools().
Issue #336: Removed deprecation from ez_setup.use_setuptools, as it is clearly still used by buildout's bootstrap. ez_setup remains deprecated for use by individual packages.
Simplified implementation of ez_setup.use_setuptools.

12.1

BB Pull Request #118: Soften warning for non-normalized versions in Distribution.

12.0.5

Issue #339: Correct Attribute reference in cant_write_to_target.
Issue #336: Deprecated ez_setup.use_setuptools.

12.0.4

Issue #335: Fix script header generation on Windows.

12.0.3

Fixed incorrect class attribute in install_scripts. Tests would be nice.

12.0.2

Issue #331: Fixed install_scripts command on Windows systems corrupting the header.

12.0.1

Restore setuptools.command.easy_install.sys_executable for pbr compatibility. For the future, tools should construct a CommandSpec explicitly.

12.0

Issue #188: Setuptools now support multiple entities in the value for build.executable, such that an executable of "/usr/bin/env my-python" may be specified. This means that systems with a specified executable whose name has spaces in the path must be updated to escape or quote that value.
Deprecated easy_install.ScriptWriter.get_writer, replaced by .best() with slightly different semantics (no force_windows flag).

11.3.1

Issue #327: Formalize and restore support for any printable character in an entry point name.

11.3

Expose EntryPoint.resolve in place of EntryPoint._load, implementing the simple, non-requiring load. Deprecated all uses of EntryPoint._load except for calling with no parameters, which is just a shortcut for ep.require(); ep.resolve();.

Apps currently invoking ep.load(require=False) should instead do the following if wanting to avoid the deprecating warning:
```
getattr(ep, "resolve", lambda: ep.load(require=False))()
```

11.2

Pip #2326: Report deprecation warning at stacklevel 2 for easier diagnosis.

11.1

Issue #281: Since Setuptools 6.1 (Issue #268), a ValueError would be raised in certain cases where VersionConflict was raised with two arguments, which occurred in pkg_resources.WorkingSet.find. This release adds support for indicating the dependent packages while maintaining support for a VersionConflict when no dependent package context is known. New unit tests now capture the expected interface.

11.0

Interop #3: Upgrade to Packaging 15.0; updates to PEP 440 so that >1.7 does not exclude 1.7.1 but does exclude 1.7.0 and 1.7.0.post1.

10.2.1

Issue #323: Fix regression in entry point name parsing.

10.2

Deprecated use of EntryPoint.load(require=False). Passing a boolean to a function to select behavior is an anti-pattern. Instead use Entrypoint._load().
Substantial refactoring of all unit tests. Tests are now much leaner and re-use a lot of fixtures and contexts for better clarity of purpose.

10.1

Issue #320: Added a compatibility implementation of sdist._default_revctrl so that systems relying on that interface do not fail (namely, Ubuntu 12.04 and similar Debian releases).

10.0.1

Issue #319: Fixed issue installing pure distutils packages.

10.0

Issue #313: Removed built-in support for subversion. Projects wishing to retain support for subversion will need to use a third party library. The extant implementation is being ported to setuptools_svn.
Issue #315: Updated setuptools to hide its own loaded modules during installation of another package. This change will enable setuptools to upgrade (or downgrade) itself even when its own metadata and implementation change.

9.1

Prefer vendored packaging library as recommended.

9.0.1

Issue #312: Restored presence of pkg_resources API tests (doctest) to sdist.

9.0

Issue #314: Disabled support for setup_requires metadata to avoid issue where Setuptools was unable to upgrade over earlier versions.

8.4

BB Pull Request #106: Now write setup_requires metadata.

8.3

Issue #311: Decoupled pkg_resources from setuptools once again. pkg_resources is now a package instead of a module.

8.2.1

Issue #306: Suppress warnings about Version format except in select scenarios (such as installation).

8.2

BB Pull Request #85: Search egg-base when adding egg-info to manifest.

8.1

Upgrade packaging to 14.5, giving preference to "rc" as designator for release candidates over "c".
PEP-440 warnings are now raised as their own class, pkg_resources.PEP440Warning, instead of RuntimeWarning.
Disabled warnings on empty versions.

8.0.4

Upgrade packaging to 14.4, fixing an error where there is a different result for if 2.0.5 is contained within >2.0dev and >2.0.dev even though normalization rules should have made them equal.
Issue #296: Add warning when a version is parsed as legacy. This warning will make it easier for developers to recognize deprecated version numbers.

8.0.3

Issue #296: Restored support for __hash__ on parse_version results.

8.0.2

Issue #296: Restored support for __getitem__ and sort operations on parse_version result.

8.0.1

Issue #296: Restore support for iteration over parse_version result, but deprecated that usage with a warning. Fixes failure with buildout.

8.0

Implement PEP 440 within pkg_resources and setuptools. This change deprecates some version numbers such that they will no longer be installable without using the === escape hatch. See the changes to test_resources for specific examples of version numbers and specifiers that are no longer supported. Setuptools now "vendors" the packaging library.

7.0

Issue #80, Issue #209: Eggs that are downloaded for setup_requires, test_requires, etc. are now placed in a ./.eggs directory instead of directly in the current directory. This choice of location means the files can be readily managed (removed, ignored). Additionally, later phases or invocations of setuptools will not detect the package as already installed and ignore it for permanent install (See #209).

This change is indicated as backward-incompatible as installations that depend on the installation in the current directory will need to account for the new location. Systems that ignore *.egg will probably need to be adapted to ignore .eggs. The files will need to be manually moved or will be retrieved again. Most use cases will require no attention.

6.1

Issue #268: When resolving package versions, a VersionConflict now reports which package previously required the conflicting version.

6.0.2

Issue #262: Fixed regression in pip install due to egg-info directories being omitted. Re-opens Issue #118.

6.0.1

Issue #259: Fixed regression with namespace package handling on single version, externally managed installs.

6.0

Issue #100: When building a distribution, Setuptools will no longer match default files using platform-dependent case sensitivity, but rather will only match the files if their case matches exactly. As a result, on Windows and other case-insensitive file systems, files with names such as 'readme.txt' or 'README.TXT' will be omitted from the distribution and a warning will be issued indicating that 'README.txt' was not found. Other filenames affected are:
- README.rst
- README
- setup.cfg
- setup.py (or the script name)
- test/test*.py
Any users producing distributions with filenames that match those above case-insensitively, but not case-sensitively, should rename those files in their repository for better portability.
BB Pull Request #72: When using single_version_externally_managed, the exclusion list now includes Python 3.2 __pycache__ entries.
BB Pull Request #76 and BB Pull Request #78: lines in top_level.txt are now ordered deterministically.
Issue #118: The egg-info directory is now no longer included in the list of outputs.
Issue #258: Setuptools now patches distutils msvc9compiler to recognize the specially-packaged compiler package for easy extension module support on Python 2.6, 2.7, and 3.2.

5.8

Issue #237: pkg_resources now uses explicit detection of Python 2 vs. Python 3, supporting environments where builtins have been patched to make Python 3 look more like Python 2.

5.7

Issue #240: Based on real-world performance measures against 5.4, zip manifests are now cached in all circumstances. The PKG_RESOURCES_CACHE_ZIP_MANIFESTS environment variable is no longer relevant. The observed "memory increase" referenced in the 5.4 release notes and detailed in Issue #154 was likely not an increase over the status quo, but rather only an increase over not storing the zip info at all.

5.6

Issue #242: Use absolute imports in svn_utils to avoid issues if the installing package adds an xml module to the path.

5.5.1

Issue #239: Fix typo in 5.5 such that fix did not take.

5.5

Issue #239: Setuptools now includes the setup_requires directive on Distribution objects and validates the syntax just like install_requires and tests_require directives.

5.4.2

Issue #236: Corrected regression in execfile implementation for Python 2.6.

5.4.1

Python #7776: (ssl_support) Correct usage of host for validation when tunneling for HTTPS.

5.4

Issue #154: pkg_resources will now cache the zip manifests rather than re-processing the same file from disk multiple times, but only if the environment variable PKG_RESOURCES_CACHE_ZIP_MANIFESTS is set. Clients that package many modules in the same zip file will see some improvement in startup time by enabling this feature. This feature is not enabled by default because it causes a substantial increase in memory usage.

5.3

Issue #185: Make svn tagging work on the new style SVN metadata. Thanks cazabon!
Prune revision control directories (e.g .svn) from base path as well as sub-directories.

5.2

Added a Developer Guide to the official documentation.
Some code refactoring and cleanup was done with no intended behavioral changes.
During install_egg_info, the generated lines for namespace package .pth files are now processed even during a dry run.

5.1

Issue #202: Implemented more robust cache invalidation for the ZipImporter, building on the work in Issue #168. Special thanks to Jurko Gospodnetic and PJE.

5.0.2

Issue #220: Restored script templates.

5.0.1

Renamed script templates to end with .tmpl now that they no longer need to be processed by 2to3. Fixes spurious syntax errors during build/install.

5.0

Issue #218: Re-release of 3.8.1 to signal that it supersedes 4.x.
Incidentally, script templates were updated not to include the triple-quote escaping.

3.7.1 and 3.8.1 and 4.0.1

Issue #213: Use legacy StringIO behavior for compatibility under pbr.
Issue #218: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed from the available versions to install.

4.0

Issue #210: setup.py develop now copies scripts in binary mode rather than text mode, matching the behavior of the install command.

3.8

Extend Issue #197 workaround to include all Python 3 versions prior to 3.2.2.

3.7

Issue #193: Improved handling of Unicode filenames when building manifests.

3.6

Issue #203: Honor proxy settings for Powershell downloader in the bootstrap routine.

3.5.2

Issue #168: More robust handling of replaced zip files and stale caches. Fixes ZipImportError complaining about a 'bad local header'.

3.5.1

Issue #199: Restored install._install for compatibility with earlier NumPy versions.

3.5

Issue #195: Follow symbolic links in find_packages (restoring behavior broken in 3.4).
Issue #197: On Python 3.1, PKG-INFO is now saved in a UTF-8 encoding instead of sys.getpreferredencoding to match the behavior on Python 2.6-3.4.
Issue #192: Preferred bootstrap location is now https://bootstrap.pypa.io/ez_setup.py (mirrored from former location).

3.4.4

Issue #184: Correct failure where find_package over-matched packages when directory traversal isn't short-circuited.

3.4.3

Issue #183: Really fix test command with Python 3.1.

3.4.2

Issue #183: Fix additional regression in test command on Python 3.1.

3.4.1

Issue #180: Fix regression in test command not caught by py.test-run tests.

3.4

Issue #176: Add parameter to the test command to support a custom test runner: --test-runner or -r.
Issue #177: Now assume most common invocation to install command on platforms/environments without stack support (issuing a warning). Setuptools now installs naturally on IronPython. Behavior on CPython should be unchanged.

3.3

Add include parameter to setuptools.find_packages().

3.2

BB Pull Request #39: Add support for C++ targets from Cython .pyx files.
Issue #162: Update dependency on certifi to 1.0.1.
Issue #164: Update dependency on wincertstore to 0.2.

3.1

Issue #161: Restore Features functionality to allow backward compatibility (for Features) until the uses of that functionality is sufficiently removed.

3.0.2

Correct typo in previous bugfix.

3.0.1

Issue #157: Restore support for Python 2.6 in bootstrap script where zipfile.ZipFile does not yet have support for context managers.

3.0

Issue #125: Prevent Subversion support from creating a ~/.subversion directory just for checking the presence of a Subversion repository.
Issue #12: Namespace packages are now imported lazily. That is, the mere declaration of a namespace package in an egg on sys.path no longer causes it to be imported when pkg_resources is imported. Note that this change means that all of a namespace package's __init__.py files must include a declare_namespace() call in order to ensure that they will be handled properly at runtime. In 2.x it was possible to get away without including the declaration, but only at the cost of forcing namespace packages to be imported early, which 3.0 no longer does.
Issue #148: When building (bdist_egg), setuptools no longer adds __init__.py files to namespace packages. Any packages that rely on this behavior will need to create __init__.py files and include the declare_namespace().
Issue #7: Setuptools itself is now distributed as a zip archive in addition to tar archive. ez_setup.py now uses zip archive. This approach avoids the potential security vulnerabilities presented by use of tar archives in ez_setup.py. It also leverages the security features added to ZipFile.extract in Python 2.7.4.
Issue #65: Removed deprecated Features functionality.
BB Pull Request #28: Remove backport of _bytecode_filenames which is available in Python 2.6 and later, but also has better compatibility with Python 3 environments.
Issue #156: Fix spelling of __PYVENV_LAUNCHER__ variable.

2.2

Issue #141: Restored fix for allowing setup_requires dependencies to override installed dependencies during setup.
Issue #128: Fixed issue where only the first dependency link was honored in a distribution where multiple dependency links were supplied.

2.1.2

Issue #144: Read long_description using codecs module to avoid errors installing on systems where LANG=C.

2.1.1

Issue #139: Fix regression in re_finder for CVS repos (and maybe Git repos as well).

2.1

Issue #129: Suppress inspection of *.whl files when searching for files in a zip-imported file.
Issue #131: Fix RuntimeError when constructing an egg fetcher.

2.0.2

Fix NameError during installation with Python implementations (e.g. Jython) not containing parser module.
Fix NameError in sdist:re_finder.

2.0.1

Issue #124: Fixed error in list detection in upload_docs.

2.0

Issue #121: Exempt lib2to3 pickled grammars from DirectorySandbox.
Issue #41: Dropped support for Python 2.4 and Python 2.5. Clients requiring setuptools for those versions of Python should use setuptools 1.x.
Removed setuptools.command.easy_install.HAS_USER_SITE. Clients expecting this boolean variable should use site.ENABLE_USER_SITE instead.
Removed pkg_resources.ImpWrapper. Clients that expected this class should use pkgutil.ImpImporter instead.

1.4.2

Issue #116: Correct TypeError when reading a local package index on Python 3.

1.4.1

Issue #114: Use sys.getfilesystemencoding for decoding config in bdist_wininst distributions.

Issue #105 and Issue #113: Establish a more robust technique for determining the terminal encoding:

1. Try ``getpreferredencoding``
2. If that returns US_ASCII or None, try the encoding from
   ``getdefaultlocale``. If that encoding was a "fallback" because Python
   could not figure it out from the environment or OS, encoding remains
   unresolved.
3. If the encoding is resolved, then make sure Python actually implements
   the encoding.
4. On the event of an error or unknown codec, revert to fallbacks
   (UTF-8 on Darwin, ASCII on everything else).
5. On the encoding is 'mac-roman' on Darwin, use UTF-8 as 'mac-roman' was
   a bug on older Python releases.

On a side note, it would seem that the encoding only matters for when SVN
does not yet support ``--xml`` and when getting repository and svn version
numbers. The ``--xml`` technique should yield UTF-8 according to some
messages on the SVN mailing lists. So if the version numbers are always
7-bit ASCII clean, it may be best to only support the file parsing methods
for legacy SVN releases and support for SVN without the subprocess command
would simple go away as support for the older SVNs does.

1.4

Issue #27: easy_install will now use credentials from .pypirc if present for connecting to the package index.
BB Pull Request #21: Omit unwanted newlines in package_index._encode_auth when the username/password pair length indicates wrapping.

1.3.2

Issue #99: Fix filename encoding issues in SVN support.

1.3.1

Remove exuberant warning in SVN support when SVN is not used.

1.3

Address security vulnerability in SSL match_hostname check as reported in Python #17997.
Prefer backports.ssl_match_hostname for backport implementation if present.
Correct NameError in ssl_support module (socket.error).

1.2

Issue #26: Add support for SVN 1.7. Special thanks to Philip Thiem for the contribution.
Issue #93: Wheels are now distributed with every release. Note that as reported in Issue #108, as of Pip 1.4, scripts aren't installed properly from wheels. Therefore, if using Pip to install setuptools from a wheel, the easy_install command will not be available.
Setuptools "natural" launcher support, introduced in 1.0, is now officially supported.

1.1.7

Fixed behavior of NameError handling in 'script template (dev).py' (script launcher for 'develop' installs).
ez_setup.py now ensures partial downloads are cleaned up following a failed download.
Distribute #363 and Issue #55: Skip an sdist test that fails on locales other than UTF-8.

1.1.6

Distribute #349: sandbox.execfile now opens the target file in binary mode, thus honoring a BOM in the file when compiled.

1.1.5

Issue #69: Second attempt at fix (logic was reversed).

1.1.4

Issue #77: Fix error in upload command (Python 2.4).

1.1.3

Fix NameError in previous patch.

1.1.2

Issue #69: Correct issue where 404 errors are returned for URLs with fragments in them (such as #egg=).

1.1.1

Issue #75: Add --insecure option to ez_setup.py to accommodate environments where a trusted SSL connection cannot be validated.
Issue #76: Fix AttributeError in upload command with Python 2.4.

1.1

Issue #71 (Distribute #333): EasyInstall now puts less emphasis on the condition when a host is blocked via --allow-hosts.
Issue #72: Restored Python 2.4 compatibility in ez_setup.py.

1.0

Issue #60: On Windows, Setuptools supports deferring to another launcher, such as Vinay Sajip's pylauncher (included with Python 3.3) to launch console and GUI scripts and not install its own launcher executables. This experimental functionality is currently only enabled if the SETUPTOOLS_LAUNCHER environment variable is set to "natural". In the future, this behavior may become default, but only after it has matured and seen substantial adoption. The SETUPTOOLS_LAUNCHER also accepts "executable" to force the default behavior of creating launcher executables.
Issue #63: Bootstrap script (ez_setup.py) now prefers Powershell, curl, or wget for retrieving the Setuptools tarball for improved security of the install. The script will still fall back to a simple urlopen on platforms that do not have these tools.
Issue #65: Deprecated the Features functionality.
Issue #52: In VerifyingHTTPSConn, handle a tunnelled (proxied) connection.

Backward-Incompatible Changes

This release includes a couple of backward-incompatible changes, but most if not all users will find 1.0 a drop-in replacement for 0.9.

Issue #50: Normalized API of environment marker support. Specifically, removed line number and filename from SyntaxErrors when returned from pkg_resources.invalid_marker. Any clients depending on the specific string representation of exceptions returned by that function may need to be updated to account for this change.
Issue #50: SyntaxErrors generated by pkg_resources.invalid_marker are normalized for cross-implementation consistency.
Removed --ignore-conflicts-at-my-risk and --delete-conflicting options to easy_install. These options have been deprecated since 0.6a11.

0.9.8

Issue #53: Fix NameErrors in _vcs_split_rev_from_url.

0.9.7

Issue #49: Correct AttributeError on PyPy where a hashlib.HASH object does not have a .name attribute.
Issue #34: Documentation now refers to bootstrap script in code repository referenced by bookmark.
Add underscore-separated keys to environment markers (markerlib).

0.9.6

Issue #44: Test failure on Python 2.4 when MD5 hash doesn't have a .name attribute.

0.9.5

Python #17980: Fix security vulnerability in SSL certificate validation.

0.9.4

Issue #43: Fix issue (introduced in 0.9.1) with version resolution when upgrading over other releases of Setuptools.

0.9.3

Issue #42: Fix new AttributeError introduced in last fix.

0.9.2

Issue #42: Fix regression where blank checksums would trigger an AttributeError.

0.9.1

Distribute #386: Allow other positional and keyword arguments to os.open.
Corrected dependency on certifi mis-referenced in 0.9.

0.9

package_index now validates hashes other than MD5 in download links.

0.8

Code base now runs on Python 2.4 - Python 3.3 without Python 2to3 conversion.

0.7.8

Distribute #375: Yet another fix for yet another regression.

0.7.7

Distribute #375: Repair AttributeError created in last release (redo).
Issue #30: Added test for get_cache_path.

0.7.6

Distribute #375: Repair AttributeError created in last release.

0.7.5

Issue #21: Restore Python 2.4 compatibility in test_easy_install.
Distribute #375: Merged additional warning from Distribute 0.6.46.

0.7.4

Issue #20: Fix comparison of parsed SVN version on Python 3.

0.7.3

Issue #1: Disable installation of Windows-specific files on non-Windows systems.
Use new sysconfig module with Python 2.7 or >=3.2.

0.7.2

Issue #14: Use markerlib when the parser module is not available.
Issue #10: ez_setup.py now uses HTTPS to download setuptools from PyPI.

0.7.1

Fix NameError (Issue #3) again - broken in bad merge.

0.7

Merged Setuptools and Distribute. See docs/merge.txt for details.

Added several features that were slated for setuptools 0.6c12:

Index URL now defaults to HTTPS.
Added experimental environment marker support. Now clients may designate a PEP-426 environment marker for "extra" dependencies. Setuptools uses this feature in setup.py for optional SSL and certificate validation support on older platforms. Based on Distutils-SIG discussions, the syntax is somewhat tentative. There should probably be a PEP with a firmer spec before the feature should be considered suitable for use.
Added support for SSL certificate validation when installing packages from an HTTPS service.

0.7b4

Issue #3: Fixed NameError in SSL support.

0.6.49

Move warning check in get_cache_path to follow the directory creation to avoid errors when the cache path does not yet exist. Fixes the error reported in Distribute #375.

0.6.42

External links finder no longer yields duplicate links.
Distribute #337: Moved site.py to setuptools/site-patch.py (graft of very old patch from setuptools trunk which inspired PR #31).

0.6.41

Distribute #27: Use public api for loading resources from zip files rather than the private method _zip_directory_cache.
Added a new function easy_install.get_win_launcher which may be used by third-party libraries such as buildout to get a suitable script launcher.

Distribute #143: Launcher scripts, including easy_install itself, are now accompanied by a manifest on 32-bit Windows environments to avoid the Installer Detection Technology and thus undesirable UAC elevation described in this Microsoft article.

0.6.36

BB Pull Request #35: In Buildout #64, it was reported that under Python 3, installation of distutils scripts could attempt to copy the __pycache__ directory as a file, causing an error, apparently only under Windows. Easy_install now skips all directories when processing metadata scripts.

0.6.35

Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in how it parses version numbers.

Distribute #278: Restored compatibility with distribute 0.6.22 and setuptools 0.6. Updated the documentation to match more closely with the version parsing as intended in setuptools 0.6.

```
PYTHONIOENCODING=utf8 pip install numpy
```
Fix for encoding issue when installing from Windows executable on Python 3.
Distribute #323: Allow setup_requires requirements to supercede installed requirements. Added some new keyword arguments to existing pkg_resources methods. Also had to updated how __path__ is handled for namespace packages to ensure that when a new egg distribution containing a namespace package is placed on sys.path, the entries in __path__ are found in the same order they would have been in had that egg been on the path when pkg_resources was first imported.

0.6.30

Distribute #328: Clean up temporary directories in distribute_setup.py.
Fix fatal bug in distribute_setup.py.

Distribute #299: The develop command didn't work on Python 3, when using 2to3, as the egg link would go to the Python 2 source. Linking to the 2to3'd code in build/lib makes it work, although you will have to rebuild the module before testing it.
Distribute #306: Even if 2to3 is used, we build in-place under Python 2.
Distribute #307: Prints the full path when .svn/entries is broken.
Distribute #313: Support for sdist subcommands (Python 2.7)

Distribute #58: Added --user support to the develop command
Distribute #11: Generated scripts now wrap their call to the script entry point in the standard "if name == 'main'"
Added the 'DONT_PATCH_SETUPTOOLS' environment variable, so virtualenv can drive an installation that doesn't patch a global setuptools.
Reviewed unladen-swallow specific change from http://code.google.com/p/unladen-swallow/source/detail?spec=svn875&r=719 and determined that it no longer applies. Distribute should work fine with Unladen Swallow 2009Q3.

Added a warning if a namespace package is declared, but its parent package is not also declared as a namespace.

Support Subversion 1.5

Removed use of deprecated md5 module if hashlib is available

Fixed bdist_wininst upload trying to upload the .exe twice

Fixed bdist_egg putting a native_libs.txt in the source package's .egg-info, when it should only be in the built egg's EGG-INFO.

Ensure that _full_name is set on all shared libs before extensions are checked for shared lib usage. (Fixes a bug in the experimental shared library build support.)

Fix to allow unpacked eggs containing native libraries to fail more gracefully under Google App Engine (with an ImportError loading the C-based module, instead of getting a NameError).

0.6c7

Fixed distutils.filelist.findall() crashing on broken symlinks, and egg_info command failing on new, uncommitted SVN directories.

Fix import problems with nested namespace packages installed via --root or --single-version-externally-managed, due to the parent package not having the child package as an attribute.

0.6c6

Added --egg-path option to develop command, allowing you to force .egg-link files to use relative paths (allowing them to be shared across platforms on a networked drive).

Fix not building binary RPMs correctly.

Fix "eggsecutables" (such as setuptools' own egg) only being runnable with bash-compatible shells.

Fix #! parsing problems in Windows .exe script wrappers, when there was whitespace inside a quoted argument or at the end of the #! line (a regression introduced in 0.6c4).

Fix test command possibly failing if an older version of the project being tested was installed on sys.path ahead of the test source directory.

Fix find_packages() treating ez_setup and directories with . in their names as packages.

0.6c5

Fix uploaded bdist_rpm packages being described as bdist_egg packages under Python versions less than 2.5.

Fix uploaded bdist_wininst packages being described as suitable for "any" version by Python 2.5, even if a --target-version was specified.

0.6c4

Overhauled Windows script wrapping to support bdist_wininst better. Scripts installed with bdist_wininst will always use #!python.exe or #!pythonw.exe as the executable name (even when built on non-Windows platforms!), and the wrappers will look for the executable in the script's parent directory (which should find the right version of Python).

Fix upload command not uploading files built by bdist_rpm or bdist_wininst under Python 2.3 and 2.4.

Add support for "eggsecutable" headers: a #!/bin/sh script that is prepended to an .egg file to allow it to be run as a script on Unix-ish platforms. (This is mainly so that setuptools itself can have a single-file installer on Unix, without doing multiple downloads, dealing with firewalls, etc.)

Fix problem with empty revision numbers in Subversion 1.4 entries files

Use cross-platform relative paths in easy-install.pth when doing develop and the source directory is a subdirectory of the installation target directory.

Fix a problem installing eggs with a system packaging tool if the project contained an implicit namespace package; for example if the setup() listed a namespace package foo.bar without explicitly listing foo as a namespace package.

0.6c3

Fixed breakages caused by Subversion 1.4's new "working copy" format

0.6c2

The ez_setup module displays the conflicting version of setuptools (and its installation location) when a script requests a version that's not available.

Running setup.py develop on a setuptools-using project will now install setuptools if needed, instead of only downloading the egg.

0.6c1

Fixed AttributeError when trying to download a setup_requires dependency when a distribution lacks a dependency_links setting.

Made zip-safe and not-zip-safe flag files contain a single byte, so as to play better with packaging tools that complain about zero-length files.

Made setup.py develop respect the --no-deps option, which it previously was ignoring.

Support extra_path option to setup() when install is run in backward-compatibility mode.

Source distributions now always include a setup.cfg file that explicitly sets egg_info options such that they produce an identical version number to the source distribution's version number. (Previously, the default version number could be different due to the use of --tag-date, or if the version was overridden on the command line that built the source distribution.)

0.6b4

Fix register not obeying name/version set by egg_info command, if egg_info wasn't explicitly run first on the same command line.

Added --no-date and --no-svn-revision options to egg_info command, to allow suppressing tags configured in setup.cfg.

Fixed redundant warnings about missing README file(s); it should now appear only if you are actually a source distribution.

0.6b3

Fix bdist_egg not including files in subdirectories of .egg-info.

Allow .py files found by the include_package_data option to be automatically included. Remove duplicate data file matches if both include_package_data and package_data are used to refer to the same files.

0.6b1

Strip module from the end of compiled extension modules when computing the name of a .py loader/wrapper. (Python's import machinery ignores this suffix when searching for an extension module.)

0.6a11

Added test_loader keyword to support custom test loaders

Added setuptools.file_finders entry point group to allow implementing revision control plugins.

Added --identity option to upload command.

Added dependency_links to allow specifying URLs for --find-links.

Enhanced test loader to scan packages as well as modules, and call additional_tests() if present to get non-unittest tests.

Support namespace packages in conjunction with system packagers, by omitting the installation of any __init__.py files for namespace packages, and adding a special .pth file to create a working package in sys.modules.

Made --single-version-externally-managed automatic when --root is used, so that most system packagers won't require special support for setuptools.

Fixed setup_requires, tests_require, etc. not using setup.cfg or other configuration files for their option defaults when installing, and also made the install use --multi-version mode so that the project directory doesn't need to support .pth files.

MANIFEST.in is now forcibly closed when any errors occur while reading it. Previously, the file could be left open and the actual error would be masked by problems trying to remove the open file on Windows systems.

0.6a10

Fixed the develop command ignoring --find-links.

0.6a9

The sdist command no longer uses the traditional MANIFEST file to create source distributions. MANIFEST.in is still read and processed, as are the standard defaults and pruning. But the manifest is built inside the project's .egg-info directory as SOURCES.txt, and it is rebuilt every time the egg_info command is run.

Added the include_package_data keyword to setup(), allowing you to automatically include any package data listed in revision control or MANIFEST.in

Added the exclude_package_data keyword to setup(), allowing you to trim back files included via the package_data and include_package_data options.

Fixed --tag-svn-revision not working when run from a source distribution.

Added warning for namespace packages with missing declare_namespace()

Added tests_require keyword to setup(), so that e.g. packages requiring nose to run unit tests can make this dependency optional unless the test command is run.

Made all commands that use easy_install respect its configuration options, as this was causing some problems with setup.py install.

Added an unpack_directory() driver to setuptools.archive_util, so that you can process a directory tree through a processing filter as if it were a zipfile or tarfile.

Added an internal install_egg_info command to use as part of old-style install operations, that installs an .egg-info directory with the package.

Added a --single-version-externally-managed option to the install command so that you can more easily wrap a "flat" egg in a system package.

Enhanced bdist_rpm so that it installs single-version eggs that don't rely on a .pth file. The --no-egg option has been removed, since all RPMs are now built in a more backwards-compatible format.

Support full roundtrip translation of eggs to and from bdist_wininst format. Running bdist_wininst on a setuptools-based package wraps the egg in an .exe that will safely install it as an egg (i.e., with metadata and entry-point wrapper scripts), and easy_install can turn the .exe back into an .egg file or directory and install it as such.

0.6a8

Fixed some problems building extensions when Pyrex was installed, especially with Python 2.4 and/or packages using SWIG.

Made develop command accept all the same options as easy_install, and use the easy_install command's configuration settings as defaults.

Made egg_info --tag-svn-revision fall back to extracting the revision number from PKG-INFO in case it is being run on a source distribution of a snapshot taken from a Subversion-based project.

Automatically detect .dll, .so and .dylib files that are being installed as data, adding them to native_libs.txt automatically.

Fixed some problems with fresh checkouts of projects that don't include .egg-info/PKG-INFO under revision control and put the project's source code directly in the project directory. If such a package had any requirements that get processed before the egg_info command can be run, the setup scripts would fail with a "Missing 'Version:' header and/or PKG-INFO file" error, because the egg runtime interpreted the unbuilt metadata in a directory on sys.path (i.e. the current directory) as being a corrupted egg. Setuptools now monkeypatches the distribution metadata cache to pretend that the egg has valid version information, until it has a chance to make it actually be so (via the egg_info command).

0.6a5

Fixed missing gui/cli .exe files in distribution. Fixed bugs in tests.

0.6a3

Added gui_scripts entry point group to allow installing GUI scripts on Windows and other platforms. (The special handling is only for Windows; other platforms are treated the same as for console_scripts.)

0.6a2

Added console_scripts entry point group to allow installing scripts without the need to create separate script files. On Windows, console scripts get an .exe wrapper so you can just type their name. On other platforms, the scripts are written without a file extension.

0.6a1

Added support for building "old-style" RPMs that don't install an egg for the target package, using a --no-egg option.

The build_ext command now works better when using the --inplace option and multiple Python versions. It now makes sure that all extensions match the current Python version, even if newer copies were built for a different Python version.

The upload command no longer attaches an extra .zip when uploading eggs, as PyPI now supports egg uploads without trickery.

The ez_setup script/module now displays a warning before downloading the setuptools egg, and attempts to check the downloaded egg against an internal MD5 checksum table.

Fixed the --tag-svn-revision option of egg_info not finding the latest revision number; it was using the revision number of the directory containing setup.py, not the highest revision number in the project.

Added eager_resources setup argument

The sdist command now recognizes Subversion "deleted file" entries and does not include them in source distributions.

setuptools now embeds itself more thoroughly into the distutils, so that other distutils extensions (e.g. py2exe, py2app) will subclass setuptools' versions of things, rather than the native distutils ones.

Added entry_points and setup_requires arguments to setup(); setup_requires allows you to automatically find and download packages that are needed in order to build your project (as opposed to running it).

setuptools now finds its commands, setup() argument validators, and metadata writers using entry points, so that they can be extended by third-party packages. See Creating distutils Extensions for more details.

The vestigial depends command has been removed. It was never finished or documented, and never would have worked without EasyInstall - which it pre-dated and was never compatible with.

0.5a12

The zip-safety scanner now checks for modules that might be used with python -m, and marks them as unsafe for zipping, since Python 2.4 can't handle -m on zipped modules.

0.5a11

Fix breakage of the "develop" command that was caused by the addition of --always-unzip to the easy_install command.

0.5a9

Include svn:externals directories in source distributions as well as normal subversion-controlled files and directories.

Added exclude=patternlist option to setuptools.find_packages()

Changed --tag-svn-revision to include an "r" in front of the revision number for better readability.

Added ability to build eggs without including source files (except for any scripts, of course), using the --exclude-source-files option to bdist_egg.

setup.py install now automatically detects when an "unmanaged" package or module is going to be on sys.path ahead of a package being installed, thereby preventing the newer version from being imported. If this occurs, a warning message is output to sys.stderr, but installation proceeds anyway. The warning message informs the user what files or directories need deleting, and advises them they can also use EasyInstall (with the --delete-conflicting option) to do it automatically.

The egg_info command now adds a top_level.txt file to the metadata directory that lists all top-level modules and packages in the distribution. This is used by the easy_install command to find possibly-conflicting "unmanaged" packages when installing the distribution.

Added zip_safe and namespace_packages arguments to setup(). Added package analysis to determine zip-safety if the zip_safe flag is not given, and advise the author regarding what code might need changing.

Fixed the swapped -d and -b options of bdist_egg.

0.5a8

The "egg_info" command now always sets the distribution metadata to "safe" forms of the distribution name and version, so that distribution files will be generated with parseable names (i.e., ones that don't include '-' in the name or version). Also, this means that if you use the various --tag options of "egg_info", any distributions generated will use the tags in the version, not just egg distributions.

Added support for defining command aliases in distutils configuration files, under the "[aliases]" section. To prevent recursion and to allow aliases to call the command of the same name, a given alias can be expanded only once per command-line invocation. You can define new aliases with the "alias" command, either for the local, global, or per-user configuration.

Added "rotate" command to delete old distribution files, given a set of patterns to match and the number of files to keep. (Keeps the most recently-modified distribution files matching each pattern.)

Added "saveopts" command that saves all command-line options for the current invocation to the local, global, or per-user configuration file. Useful for setting defaults without having to hand-edit a configuration file.

Added a "setopt" command that sets a single option in a specified distutils configuration file.

0.5a7

Added "upload" support for egg and source distributions, including a bug fix for "upload" and a temporary workaround for lack of .egg support in PyPI.

0.5a6

Beefed up the "sdist" command so that if you don't have a MANIFEST.in, it will include all files under revision control (CVS or Subversion) in the current directory, and it will regenerate the list every time you create a source distribution, not just when you tell it to. This should make the default "do what you mean" more often than the distutils' default behavior did, while still retaining the old behavior in the presence of MANIFEST.in.

Fixed the "develop" command always updating .pth files, even if you specified -n or --dry-run.

Slightly changed the format of the generated version when you use --tag-build on the "egg_info" command, so that you can make tagged revisions compare lower than the version specified in setup.py (e.g. by using --tag-build=dev).

0.5a5

Added develop command to setuptools-based packages. This command installs an .egg-link pointing to the package's source directory, and script wrappers that execfile() the source versions of the package's scripts. This lets you put your development checkout(s) on sys.path without having to actually install them. (To uninstall the link, use use setup.py develop --uninstall.)

Added egg_info command to setuptools-based packages. This command just creates or updates the "projectname.egg-info" directory, without building an egg. (It's used by the bdist_egg, test, and develop commands.)

Enhanced the test command so that it doesn't install the package, but instead builds any C extensions in-place, updates the .egg-info metadata, adds the source directory to sys.path, and runs the tests directly on the source. This avoids an "unmanaged" installation of the package to site-packages or elsewhere.

Made easy_install a standard setuptools command, moving it from the easy_install module to setuptools.command.easy_install. Note that if you were importing or extending it, you must now change your imports accordingly. easy_install.py is still installed as a script, but not as a module.

0.5a4

Setup scripts using setuptools can now list their dependencies directly in the setup.py file, without having to manually create a depends.txt file. The install_requires and extras_require arguments to setup() are used to create a dependencies file automatically. If you are manually creating depends.txt right now, please switch to using these setup arguments as soon as practical, because depends.txt support will be removed in the 0.6 release cycle. For documentation on the new arguments, see the setuptools.dist.Distribution class.

Setup scripts using setuptools now always install using easy_install internally, for ease of uninstallation and upgrading.

0.5a1

Added support for "self-installation" bootstrapping. Packages can now include ez_setup.py in their source distribution, and add the following to their setup.py, in order to automatically bootstrap installation of setuptools as part of their setup process:
from ez_setup import use_setuptools
use_setuptools()

from setuptools import setup
# etc...

0.4a2

Added ez_setup.py installer/bootstrap script to make initial setuptools installation easier, and to allow distributions using setuptools to avoid having to include setuptools in their source distribution.

All downloads are now managed by the PackageIndex class (which is now subclassable and replaceable), so that embedders can more easily override download logic, give download progress reports, etc. The class has also been moved to the new setuptools.package_index module.

The Installer class no longer handles downloading, manages a temporary directory, or tracks the zip_ok option. Downloading is now handled by PackageIndex, and Installer has become an easy_install command class based on setuptools.Command.

There is a new setuptools.sandbox.run_setup() API to invoke a setup script in a directory sandbox, and a new setuptools.archive_util module with an unpack_archive() API. These were split out of EasyInstall to allow reuse by other tools and applications.

setuptools.Command now supports reinitializing commands using keyword arguments to set/reset options. Also, Command subclasses can now set their command_consumes_arguments attribute to True in order to receive an args option containing the rest of the command line.

0.3a2

Added new options to bdist_egg to allow tagging the egg's version number with a subversion revision number, the current date, or an explicit tag value. Run setup.py bdist_egg --help to get more information.
