+# Introduction
+
+This document outlines the principles that drive the development of ChaiScript. ChaiScript does not intent to be the perfect tool for *every* situation, but it does intend to be a good general purpose tool for *most* situations.
+
+# Goals
+
+1. Trivially easy to integrate with C++ projects
+2. 0 external depenencies
+3. "Perfect" integration with C++
+   * Direct mapping between ChaiScript objects and C++ objects
+   * Direct mapping between ChaiScript functions and C++ functions
+   * Direct mapping between ChaiScript exceptions and C++ exceptions
+3. Never surprise the C++ developer
+   * Object lifetimes managed by the stack
+   * Familiar syntax to C++ developers
+4. Perform "well enough" to not get in the way
+
+
+# Alternatives
+
+## Sol2
+
+If you are looking for the fastest performing scripting language and don't mind Lua, you might want to consider [sol2](https://github.com/ThePhD/sol2).
+
+## SWIG
+
+If you are looking for the most flexible solution to be able to support multiple target languages, consider [SWIG](http://swig.org)

 Notes:
 =======
-Current Version: 5.8.2
+Current Version: 6.0.0
+
+### Changes since 5.8.6
+
+*6.0.0 is a massive rework compared to 5.x. It now requires a C++14 enabled compiler*
+
+#### Compiler Requirements
+
+* MSVC 2015 or greater
+* g++ 4.9 or greater
+* clang 3.6 or greater
+
+#### Breaking Changes
+
+* Instantiating a ChaiScript object now, by default, builds the stdlib in
+  * This was done to address the most common support issues of loading stdlib dynamically at runtime
+  * If you want the old behavior, use include/chaiscript/chaiscript_basic.hpp
+* Headers have been reorganized to fully separate stdlib/parser/engine from each other (some faster builds)
+* Bootstrap functions no longer return a reference to the module added to (compile time savings)
+* It's now no longer possible modify AST_Nodes (compile time, runtime efficiency)
+* Function annotations no longer exist (simplifies code, reduces compile time, compile size)
+
+#### New Features Added
+
+* Modular optimization system; this can be accessed via the ChaiScript_Basic interface
+* Execution tracing capability; also accessed via ChaiScript_Basic interface
+* range-based for loops `for( id : container ) { }` (much better performance than other loop types)
+* If-init expressions (ala C++17)
+* Support for passing r-value references to functions
+* Support for containing unique_ptr
+* Add helpers for exposing enum classes to ChaiScript
+* Allow typed ChaiScript defined functions to perform conversions on call #303
+
+#### Improvements
+
+* Compile time improvements
+* Compile size improvements
+* Significant runtime improvements (see "Modular optimization system")
+* Significant parser improvements, both with parse-time and parser initialization time (Thanks @niXman)
+* Fix type conversion to bool in conditionals
+
+#### Improvements Still Need To Be Made
+
+* File location tracking has been rewritten; this currently means error location reporting is not as good as it was
+* Tracing capability needs to be tested and vetted
+
+### Changes since 5.8.5
+* Optimize away `return` statements in lambdas also
+* Allow conversions to bool in conditionals
+* Don't allow `class` statements inside of scopes
+* Properly error when a dynamic object non-function member is called
+
+### Changes since 5.8.4
+* Fix order of operations for prefix operators
+* Make sure atomics are initialized properly
+* Remove parsing of unused prefix `&` operator
+
+### Changes since 5.8.3
+* Fix case with some numeric conversions mixed with numerics that do not need conversion
+
+### Changes since 5.8.2
+* Add support for reference of pointer return types
 
 ### Changes since 5.8.1
 * Allow casting to non-const & std::shared_ptr<T>
