* Reoptimized math.min/max/bit32 builtins assuming at least 2 arguments are used (1-2% lift on some benchmarks) * Type errors that mention function types no longer have redundant parenthesis around return type * Luau REPL now supports --compile=remarks which displays the source code with optimization remarks embedded as comments * Builtin calls are slightly faster when called with 1-2 arguments (~1% improvement in some benchmarks)
