+Introduction
+============
+
+ChaiScript is one of the only embedded scripting language designed from the 
+ground up to directly target C++ and take advantage of modern C++ development 
+techniques, working with the developer like he expects it to work.  Being a 
+native C++ application, it has some advantages over existing embedded scripting 
+languages:
+
+1) It uses a header-only approach, which makes it easy to integrate with 
+   existing projects.
+2) It maintains type safety between your C++ application and the user scripts.
+3) It supports a variety of C++ techniques including callbacks, overloaded 
+   functions, class methods, and stl containers.
+
+Requirements
+============
+
+ChaiScript requires a recent version of Boost (http://www.boost.org) to build.
+
+Usage
+=====
+
+* Add the ChaiScript include directory to your project's header search path
+* Add `#include <chaiscript/chaiscript.hpp>` to your source file
+* Instantiate the ChaiScript engine in your application.  For example, create 
+  a new engine with the name `chai` like so: `chaiscript::ChaiScript chai`
+
+Once instantiated, the engine is ready to start running ChaiScript source.  You 
+have two main options for processing ChaiScript source: a line at a time using 
+`chai.eval(string)` and a file at a time using `chai.eval_file(fname)`
+
+To make functions in your C++ code visible to scripts, they must be registered 
+with the scripting engine.  To do so, call add:
+
+    chai.add(chaiscript::fun(&my_function), "my_function_name");
+
+Once registered the function will be visible to scripts as "my_function_name"
+
+Examples
+========
+
+ChaiScript is similar to ECMAScript (aka JavaScript(tm)), but with some 
+modifications to make it easier to use.  For usage examples see the "samples" 
+directory, and for more in-depth look at the language, the unit tests in the 
+"unittests" directory cover the most ground.
+
+For examples of how to register parts of your C++ application, see 
+"example.cpp" in the "src" directory. Example.cpp is verbose and shows every 
+possible way of working with the library. For further documentation generate 
+the doxygen documentation in the build folder or see the website 
+http://www.chaiscript.com.
+
+
+The shortest complete example possible follows:
+
+    /// main.cpp
+
+    #include <chaiscript/chaiscript.hpp>
+
+    double function(int i, double j)
+    {
+      return i * j;
+    }
+
+    int main()
+    {
+      chaiscript::ChaiScript chai;
+      chai.add(chaiscript::fun(&function), "function");
+
+      double d = chai.eval<double>("function(3, 4.75);");
+    }
+
+

-[Introduction]
-
-ChaiScript is one of the only embedded scripting language designed from the ground up to directly target C++ and take advantage of modern C++ development techniques, working with the developer like he expects it to work.  Being a native C++ application, it has some advantages over existing embedded scripting languages:
-
-1) It uses a header-only approach, which makes it easy to integrate with existing projects.
-2) It maintains type safety between your C++ application and the user scripts.
-3) It supports a variety of C++ techniques including callbacks, overloaded functions, class methods, and stl containers.
-
-[Requirements]
-
-ChaiScript requires a C++11 compiler to build with support for variadic templates.  It has been tested with gcc 4.7 and clang 3.1 (with libcxx).
-
-[Usage]
-
-* Add the ChaiScript include directory to your project's header search path
-* Add "#include <chaiscript/chaiscript.hpp> to your source file
-* Instantiate the ChaiScript engine in your application.  For example, create a new engine with the name 'chai' like so: "chaiscript::ChaiScript chai"
-
-Once instantiated, the engine is ready to start running ChaiScript source.  You have two main options for processing ChaiScript source: a line at a time using "chai.evaluate_string(string)" and a file at a time using "chai.evaluate_file(fname)"
-
-To make functions in your C++ code visible to scripts, they must be registered with the scripting engine.  To do so, call add:
-
-chai.add(chaiscript::fun(&my_function), "my_function_name");
-
-Once registered the function will be visible to scripts as "my_function_name"
-
-[Examples]
-
-ChaiScript is similar to ECMAScript (aka JavaScript(tm)), but with some modifications to make it easier to use.  For usage examples see the "samples" directory, and for more in-depth look at the language, the unit tests in the "unittests" directory cover the most ground.
-
-For examples of how to register parts of your C++ application, see "example.cpp" in the "src" directory. Example.cpp is verbose and shows every possible way of working with the library. For further documentation generate the doxygen documentation in the build folder or see the website http://www.chaiscript.com.
-
-The shortest complete example possible follows:
-
-/// main.cpp
-
-#include <chaiscript/chaiscript.hpp>
-
-double function(int i, double j)
-{
-  return i * j;
-}
-
-int main()
-{
-  chaiscript::ChaiScript chai;
-  chai.add(chaiscript::fun(&function), "function");
-
-  double d = chai.eval<double>("function(3, 4.75);");

+Current Version: 4.3.1
+
+Note: this is scheduled to be the last release that requires boost, new releases after this will require a C++11 compiler.
+
+### Changes since 4.3.0
+* 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
+
+### 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
+* Code cleanups
+* Eliminate global data, which makes code more portable and thread safe
+* Fix issue #79
+* Merge pretty_print fixes from @mgee #82
+* Compiler warning fixes for latest compiler releases
+* Fix threading problems
+* Fix linking error on MacOS Mavericks #88
+* Allow non-const globals
+* Make sure user cannot name a variable with `::` in it #91
+* Fix various string / map / vector `size` and `count` calls for compilers which have weird overloads for them. #90 #93 #95
+* Make module search path relative to the currently running executable
+* Build and work with wstring windows builds
+
+### Changes since 4.1.1
+* Add support for automatic conversion of arithmetic types when possible
+  and when no ambiguous method dispatch exists.
+
+### Changes since 4.1.0
+* Fix missed gcc build error in 4.1.0
+
 Changes since 4.0.0
-* Dropped boost in favor of C++11
-* Separated out stdlib to make more options for compile time improvements
+* Fix sizing of numeric constants to match that of the C++ standard
+* Add support for u,ll,l,f suffixes for numeric constants
+* Siginificant improvement in error reporting
