+
+3.4.0
+ * enhancement: add API call jent_set_fips_failure_callback as requested by Daniel Ojalvo
+ * fix: Change the SHA-3 integration: The entropy pool is now a SHA-3 state.
+It is filled with the time delta containing entropy and auxiliary data that does not contain entropy using a SHA update operation. The auxiliary data is calculated by a SHA-3 hashing of some varying state data. The time delta that contains entropy is measured about the SHA-3 hasing of the auxiliary data. This satisfies FIPS 140-3 IG D.K resolutions 4, 6, and 8.

+   used for the memory access loop
+ * Increase the memory buffer size to 512 kBytes per default based on

+ * add GCD testing and analysis suggested by Joshua Hill
+ * add fixes to APT suggested by Joshua Hill

+ * add jent_read_entropy_safe API call
+ * break up jitterentropy-base.c into various smaller code files
+
+3.0.2
+ * Small fixes suggested by Joshua Hill
+ * Update the invocation of SHA-3 invocation: each loop iteration defined by the loop shuffle is a self-contained SHA-3 operation. Therefore, the conditioning information is always *one* SHA-3 operation with different time duration.
+ * add JENT_CONF_DISABLE_LOOP_SHUFFLE config option allowing disabling of the shuffle operation
+ * Use -O0
+
+3.0.1
+ * on older GCC versions use -fstack-protector as suggested by Warszawski,
+   Diego
+ * prevent creating the internal timer thread if a high-res hardware timer is
+   found as reported by Lonnie Abelbeck

+ * SP800-90B compliance: Add RCT runtime health test
+ * SP800-90B compliance: Add Chi-Squared runtime health test as a replacement

+ * SP800-90B compliance: Increase initial entropy test to 1024 rounds
+ * SP800-90B compliance: Invoke runtime health tests during initialization
+ * remove FIPS 140-2 continuous self test (RCT covers the requirement as per
+   FIPS 140-2 IG 9.8)

+
+2.1.2:

+Hardware RNG based on CPU timing jitter
+=======================================
+
+The Jitter RNG provides a noise source using the CPU execution timing jitter.
+It does not depend on any system resource other than a high-resolution time
+stamp. It is a small-scale, yet fast entropy source that is viable in almost
+all environments and on a lot of CPU architectures.
+
+The implementation of the Jitter RNG is independent of any operating system.
+As such, it could even run on baremetal without any operating system.
+
+The design of the RNG is given in the documentation found in at
+http://www.chronox.de/jent . This documentation also covers the full
+assessment of the SP800-90B compliance as well as all required test code.
+
+API
+---
+
+The API is documented in the man page jitterentropy.3.
+
+To use the Jitter RNG, the header file jitterentropy.h must be included.
+
+Build Instructions
+==================
+
+To generate the shared library `make` followed by `make install`.
+
+Android
+-------
+
+To compile the code on Android, use the following Makefile:
+
+arch/android/Android.mk	-- NDK make file template that can be used to directly
+			   compile the CPU Jitter RNG code into Android binaries
+
+Direct CPU instructions
+-----------------------
+
+If the function in jent_get_nstime is not available, you can replace the
+jitterentropy-base-user.h with examples from the arch/ directory.
+
+Testing
+=======
+
+There are numerous tests around the Jitter RNG. Yet, they are too big to be
+loaded into the official repository. Email me, if you want them.
+
+Version Numbers
+===============
+The version numbers for this library have the following schema:
+MAJOR.MINOR.PATCHLEVEL
+
+Changes in the major number implies API and ABI incompatible changes, or
+functional changes that require consumer to be updated (as long as this
+number is zero, the API is not considered stable and can change without a
+bump of the major version).
+
+Changes in the minor version are API compatible, but the ABI may change.
+Functional enhancements only are added. Thus, a consumer can be left
+unchanged if enhancements are not considered. The consumer only needs to
+be recompiled.
+
+Patchlevel changes are API / ABI compatible. No functional changes, no
+enhancements are made. This release is a bug fixe release only. The
+consumer can be left unchanged and does not need to be recompiled.
