- A series of major optimizations to type checking performance on complex programs/types (up to two orders of magnitude speedup for programs involving huge tagged unions) - Fix a few issues encountered by UBSAN (and maybe fix s390x builds) - Fix gcc-11 test builds - Fix a rare corner case where luau_load wouldn't wake inactive threads which could result in a use-after-free due to GC - Fix CLI crash when error object that's not a string escapes to top level - Fix Makefile suffixes on macOS Co-authored-by: Rodactor <rodactor@roblox.com>
