v2.0

Added

• Reimplemented taint propagation from the ground-up, fixing a large amount of bugs and unimplemented aspects particularly around coroutines.
• Added C and Lua APIs for creating and testing C closures.
• Added C and Lua APIs for profiling and memory measurement.
• Added C and Lua APIs for high-precision timers.
• Added C and Lua APIs for querying and manipulating taint.
• Added C and Lua APIs for secure random number generation.
• Added support for the __environment metatable key to getfenv.
• Added a -p flag to the interpreter to enable performance accounting.
• Added a -t flag to the interpreter to run inline scripts (-e) or load files insecurely.
  • When this flag is specified, any modules loaded via -l will still be loaded securely.

Changed

• Build process now requires CMake 3.22 and makes use of CMake presets for common build targets. See README for more information.

Removed

• Removed the taint field on the lua_Debug to fix potential binary incompatibilities.
• Removed the "s" field from debug.getinfo. Use debug.getstacktaint() instead.
• Removed debug.forcesecure(). Use debug.setstacktaint(nil) instead.
