 Notes:
+=======
+Current Version: 5.4.0
 
- * There was overlap during the 5.x and 4.x development cycle, so some of the notes appear twice as the new features were developed for 4.x (which required boost) then ported to 5.x (which requires C++11).
- * This is the last release of 5.x, all future development will be on the final merged 6.x line.
+### Changes since 5.3.1
+* Decreased compile time and build size
+* Make "reflection" module built in (losing some of the time / build size gains)
+* Add new "class" syntax for ChaiScript defined methods and attributes see: [unittests/class.chai](unittests/class.chai) for examples
+* Minor performance enhancements
+* major to_string performance enhancements
+* Provide API for retrieving registered type name #124
+* Added strong reference to container to range object #132
 
 
+### Changes since 5.3.0
+* Add automatic conversion of arithmetic return types, following the same
+  rules as conversion of arithmetic types when passing parameters
+* Add automatic casting up the inheritence hierarchy when possible.
+* Enable travis.ci testing
+* Allow users to add globals from within script
+* Various static analysis fixes
+* Code modernization to C++11
+* Unofficial support for Haiku added
+* Fix #121 - Inability to compile on cygwin
+* Formatting fixes and spelling corrections
+* Apply "include what you use" https://code.google.com/p/include-what-you-use/
+* Apply clang-modernize
+* Various threading fixes
+* Performance improvements
+
 ### Changes since 5.2.0
 * Official support for MSVC with C++11. All major platforms and compilers are now support for C++11 release
+
+### Changes since 4.2.0
 * Enhanced unit tests
 * Add `continue` statement, fix various use cases for `for`  loops
 * Fix use of suffixed numbers in vector initialization
