* Added support for async typechecking cancellation using a token passed through frontend options * Added luaC_enumheap for building debug tools that need a graph of Luau heap In our new typechecker: * Errors or now suppressed when checking property lookup of error-suppressing unions In our native code generation (jit): * Fixed unhandled value type in NOT_ANY lowering * Fast-call tag checks will exit to VM on failure, instead of relying on a native fallback * Added vector type to the type information * Eliminated redundant direct jumps across dead blocks * Debugger APIs are now disabled for call frames executing natively * Implemented support for unwind registration on macOS 14
