- Fix type checking in branches when values were compared to string literals
- Fix type checking for property access of unions of tables in some cases
- Remove lua_State* argument from lua_Alloc callback (this changes C API to make it closer to Lua C API, see Documentation: C API #251)
- Fully enable the new paged sweeper, reducing the size of GC header by 8 bytes (on 64-bit platforms)
Changes: - Support for time tracing for analysis/compiler (not currently exposed through CLI) - Support for type pack arguments in type aliases (#83) - Basic support for require(path) in luau-analyze - Add a lint warning for table.move with 0 index as part of TableOperation lint - Remove last STL dependency from Luau.VM - Minor VS2022 performance tuning Co-authored-by: Rodactor <[email protected]>
- 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
This doesn't contain all changes for 507 yet but we might want to do the Luau 0.507 release a bit earlier to end the year sooner.
This version isn't for release because we've skipped some internal numbers due to year-end schedule changes, but it's better to merge separately.
This takes the extra bug fix for generic name confusion
