On Sept 22 ChaiScript 2.0 was released. ChaiScript is an embedded scripting language designed from the ground up specifically for use with C++. It is a header only implementation and is released under the BSD license, making it easy to integrate with your existing software. This release adds significant compile time and runtime performance improvements over previous releases, thread safety, support for ChaiScript defined object types, and exception handling. The source and binaries for common platforms can be downloaded at googlecode. Its ease of integration makes it ideal for configuration file scripting and runtime scripting for any C++ application needing dynamic content or behavior.
