* `Luau.Analyze.CLI` now has experimental support for concurrent type checking. Use the option `-jN` where `N` is the number of threads to spawn. * Improve typechecking performance by ~17% by making the function `Luau::follow` much more efficient. * Tighten up the type of `os.date` * Removed `ParseOptions::allowTypeAnnotations` and `ParseOptions::supportContinueStatement` New solver * Improve the reliability of function overload resolution * More work toward supporting parallel type checking * Fix a bug in inference of `==` and `~=` which would erroneously infer that the operands were `boolean` * Better error reporting when `for...in` loops are used incorrectly. CodeGen * Fix unwind registration when libunwind is used on Linux * Fixed replaced IR instruction use count * Convert X64 unwind info generation to standard prologue * Implement A64 unwind info support for Dwarf2 * Live in/out data for linear blocks is now created * Add side-exit VM register requirements to the IR dump * Reuse ConstPropState between block chains * Remove redundant base update --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com>
