+# Unity Test - Change Log
+
+## A Note
+
+This document captures significant features and fixes to the Unity project core source files 
+and scripts. More detail can be found in the history on Github. 
+
+This project is now tracking changes in more detail. Previous releases get less detailed as
+we move back in histroy. 
+
+Prior to 2012, the project was hosted on SourceForge.net
+Prior to 2008, the project was an internal project and not released to the public.
+
+## Log
+
+### Unity 2.6.0 ()
+
+New Features:
+
+  - Fill out missing variations of arrays, within, etc. 
+  - Add `TEST_PRINTF()`
+  - Add `TEST_MATRIX()` and `TEST_RANGE()` options and documentation
+  - Add support for searching `TEST_SOURCE_FILE()` for determining test dependencies
+  - Add Unity BDD plugin
+  - Add `UNITY_INCLUDE_EXEC_TIME` option to report test times
+  - Allow user to override test abort underlying mechanism
+
+Significant Bugfixes:
+
+  - More portable validation of NaN and Infinity. Added `UNITY_IS_NAN` and `UNITY_IS_INF` options
+  - Add `UNITY_PROGMEM` configuration option
+  - Fix overflow detection of hex values when using arrays
+  - Fix scripts broken by Ruby standard changes
+
+Other:
+
+  - Avoid pointer comparison when one is null to avoid compiler warnings
+  - Significant improvements to documentation
+  - Updates to match latest Ruby style specification
+  - Meson, CMake, PlatformIO builds
+
+### Unity 2.5.2 (January 2021)
+
+  - improvements to RUN_TEST macro and generated RUN_TEST
+  - Fix `UNITY_TEST_ASSERT_BIT(S)_HIGH`
+  - Cleaner handling of details tracking by CMock
+
+### Unity 2.5.1 (May 2020)
+
+Mostly a bugfix and stability release.
+Bonus Features:
+
+  - Optional TEST_PRINTF macro
+  - Improve self-testing procedures.
+
+### Unity 2.5.0 (October 2019)
+
+It's been a LONG time since the last release of Unity. Finally, here it is!
+There are too many updates to list here, so some highlights:
+
+  - more standards compliant (without giving up on supporting ALL compilers, no matter how quirky)
+  - many more specialized assertions for better test feedback
+  - more examples for integrating into your world
+  - many many bugfixes and tweaks
+
+### Unity 2.4.3 (November 2017)
+
+  - Allow suiteSetUp() and suiteTearDown() to be povided as normal C functions
+  - Fix & Expand Greater Than / Less Than assertions for integers
+  - Built-in option to colorize test results
+  - Documentation updates
+
+### Unity 2.4.2 (September 2017)
+
+  - Fixed bug in UNTY_TEST_ASSERT_EACH_EQUAL_*
+  - Added TEST_ASSERT_GREATER_THAN and TEST_ASSERT_LESS_THAN
+  - Updated Module Generator to stop changing names when no style given
+  - Cleanup to custom float printing for accuracy
+  - Cleanup incorrect line numbers are partial name matching
+  - Reduce warnings from using popular function names as variable names
+
+### Unity 2.4.1 (April 2017)
+
+  - test runner generator can inject defines as well as headers
+  - added a built-in floating point print routine instead of relying on printf
+  - updated to new coding and naming standard
+  - updated documentation to be markdown instead of pdf
+  - fixed many many little bugs, most of which were supplied by the community (you people are awesome!)
+  - coding standard actually enforced in CI
+
+### Unity 2.4.0 (October, 2016)
+
+  - port from SourceForge and numerous bugfixes

+#### `UNITY_IS_NAN` and `UNITY_IS_INF`
+
+If your toolchain defines `isnan` and `isinf` in `math.h` as macros, nothing needs to be done. If your toolchain doesn't define these, Unity
+will create these macros itself. You may override either or both of these defines to specify how you want to evaluate if a number is NaN or Infinity.

+_Example:_
+
+```C
+#define UNITY_IS_NAN(n) ((n != n) ? 1 : 0)
