- Improve error recovery during type checking - Initial (not fully complete) implementation for singleton types (RFC RFC: Singleton types #37) - Implement a C-friendly interface for compiler (luacode.h) - Remove C++ features from lua.h (removed default arguments from luau_load and lua_pushcfunction) - Fix lua_breakpoint behavior when enabled=false - Implement coroutine.close (RFC RFC: coroutine.close #88) Note, this introduces small breaking changes in lua.h: - luau_load env argument is now required, pass an extra 0 - lua_pushcfunction now must be called with 3 arguments; if you were calling it with 2 arguments, pass an extra NULL; if you were calling it with 4, use lua_pushcclosure. These changes are necessary to make sure lua.h can be used from pure C - the future release will make it possible by adding an option to luaconf.h to change function name mangling to be C-compatible. We don't anticipate breaking the FFI interface in the future, but this change was necessary to restore C compatibility. Closes #121 Fixes #213
