- Fix some cases where type checking would overflow the native stack - Improve autocomplete behavior when assigning a partially written function call (not currently exposed through command line tools) - Improve autocomplete type inference feedback for some expressions where previously the type would not be known - Improve quantification performance during type checking for large types - Improve type checking for table literals when the expected type of the table is known because of a type annotation - Fix type checking errors in cases where required module has errors in the resulting type - Fix debug line information for multi-line chained call sequences (Add function name information for "attempt to call a nil value" #255) - lua_newuserdata now takes 2 arguments to match Lua/LuaJIT APIs better; lua_newuserdatatagged should be used if the third argument was non-0. - lua_ref can no longer be used with LUA_REGISTRYINDEX to prevent mistakes when migrating Lua FFI (Inconsistency with lua_ref #247) - Fix assertions and possible crashes when executing script code indirectly via metatable dispatch from lua_equal/lua_lessthan/lua_getfield/etc. (Hitting a crash in an assert after lua_equal is called. #259) - Fix flamegraph scripts to run under Python 2
