2.2.5 - To be released

2.2.4 - 17 December 2015

  • Fix output of FsCheck.Xunit - was not correctly reported in all runners (by Matt Ellis)
  • Allow shrinking null for C# compatibility (by William Pleasant-Ryan)
  • Fix default generators to not rely on static dictionary - this caused some weird side-effects and behavior when overriding default generators.

2.2.3 - 26 November 2015

  • Now also reflectively generate union types with private constructors.
  • Fix bug in xunit integration: Verbose didn't show any output.

2.2.2 - 14 November 2015

  • Major performance improvements in generators, particularly reflection-based generators. (with Mårten Rånge)

2.2.1 - 5 November 2015

  • Bug fix: xUnit runner did not update failed count correctly in some cases.
  • Fix overly constrained FSharp.Core dependency in FsCheck NuGet package.

2.2.0 - 1 November 2015

  • Add QuietOnSuccess option to vanilla runner.
  • Add bigint generator.
  • Deprecate some infrequently used and incorrectly named methods.
  • Lots of internal and mostly syntactic code cleanup.
  • Switch to paket for creating NuGet packages.

2.1.0 - 30 September 2015

  • Switch to xunit 2.1. Note: Needs -noshadow argument on Mono due to Mono bug. A fix for Mono is submitted and is expected in Mono 4.3. (heroic achievement by Jon Hamm - thanks to all who tested early versions and found bugs.)
  • xunit versions < 2.1 are no longer supported. The latest FsCheck version that supports xunit 1.9.2 is currently FsCheck.Xunit 2.0.7.
  • Made Arbitrary overrides (e.g. using Arb.register, passing arbitrary to Config, or setting them in PropertyAttribute) thread-local. This is mainly to support xunit2: it runs tests in the same class in parallel by default. Not making the overrides thread local causes overrides from one test to mistakenly apply to others.
  • FsCheck.Runner.init is Obsolete, it should not longer be necessary to call it explicitly. (though I am cautious here - please report any issues.)
  • Fix for AppVeryor NuGet feed dependency problem.

2.0.7 - 20 August 2015

  • Add assembly level ExtensionAttribute so VB.NET sees extension methods too. (by Paulmichael Blasucci)

2.0.6 - 14 August 2015

  • Undo removal of GenBuilder.delay - this is needed otherwise while and for don't work correctly.
  • Optimize GenBuilder.While.
  • Add Gen.(>>=), monadic bind operator.

2.0.5 - 31 July 2015

  • Make Gen operators <*> and <!> actual operators on the Gen type, instead of functions to avoid name clashes. (by Paul Young)
  • Add FsCheck.Experimental.StateMachine for more advanced state machine-based checking, i.e. for mutable systems.
  • Fix GenBuilder.delay so that generators inside gen computation expression are not needlessly re-created.
  • Add Fun active pattern to make using shrinkable and printable functions easier.

2.0.4 - 20 July 2015

  • Fix FsCheck.NUnit NuGet package.

2.0.3 - 10 July 2015

  • Add support for Portable Class Library profiles 7,78 and 259.

2.0.2 - 7 July 2015

  • Update NuGet package with new project home.
  • Add missing frequency overload.
  • Added some more C# examples to documentation.
  • Internal changes related to use of reflection API to eventually support PCL.
  • Fix bug in Commands.
  • Improved output - now shows argument before and after shrinking.

2.0.1 - 23 May 2015

  • Because apparently there there is some problem with FsCheck.Xunit and FsCheck.NUnit's NuGet dependencies to unstable versions.

2.0.1-rc1 - 23 May 2015

  • Improve asssert failure reporting in FsCheck.Xunit (by Mark Seemann)
  • Add discard method (by Mauricio Scheffer)
  • Fix capitalization of Fscheck.NUnit package

2.0.0-alpha - 26 April 2015

  • Rename FsCheckTestCaseBuider to Builder. (potentially breaking change)
  • Add RequireQualifiedAccess to TestResult and Outcome. (breaking change for IRunner implementations and test framework integrations)
  • Remove Fluent API and SpecBuilder in favor of overloads in Prop and extension methods on Property (breaking change)
  • Add extension methods to allow working with Arbitrary from C#/VB.
  • Rename Any to Gen. Rename pretty much all methods on Any to match the existing methods they wrap on Gen module. (breaking change)
  • Add missing Gen and Arbitrary extension methods and C#/VB wrappers.
  • Make Property a real type instead of a type alias.
  • Add discard (by Mauricio Scheffer)
  • Various improvements and changes to Command interface for easier consumption, also from C#/VB (breaking change)
  • Add explicit dependency on FSharp.Core Nuget package to hopefully reduce version confusion and make things easier for C#/VB users.

1.0.4 - 9 December 2014

  • Add NonNull.

1.0.3

  • Add option to FsCheck.Xunit and FsCheck.Nunit to suppress output on success.

1.0.2 - 27 October 2014

  • Moved default Arb registration to Arb module. This should fix issues folks have been having with the default generators not being registered in time.

1.0.1 - 18 October 2014

  • Add XML docs, mostly in C# API and xUnit integration attributes.
  • Document FsCheck.Xunit and FsCheck.NUnit properly.

1.0.0 - 3 August 2014

  • Start using FAKE to automate releases
  • Release NUnit addin
  • Start using semantic versioning, hence the jump to 1.0.0
  • Start releasing all NuGet packages simultaneously and with the same version.
  • Start using FSharp.Formatting and publish documentation to github.io
  • Start building for mono on non-windows platforms.
  • Start using CI (appveyor for windows, Travis CI for MacOS).
  • Update to .NET4.5 to take advantage of ExceptionDispatchInfo.
  • Fix: sbyte overflow bug in shrinker.
  • Fix: CultureInfo generator and shrinker.

0.9.4 - 24 May 2014

  • Update to F# 3.1
  • Hardened other generators against the new null-generating string generator.

0.9.3 - 9 May 2014

  • String generator now generates null
