- Type mismatch errors now show detailed information for compound types, highlighting the mismatching component - Fix string.pack bug on ARM when packing negative numbers using unsigned formats - Implement bit32.countlz/countrz (RFC RFC: bit32.countlz/countrz #89) - Minor compiler throughput optimization (~2% faster compilation) - Improve transpiler behavior for edge cases and better test coverage (not exposed through CLI at the moment) - Improve error recovery when parsing invalid assignments - Build fixes for fuzzing targets
