* Better indentation in multi-line type mismatch error messages * Error message clone can no longer cause a stack overflow (when typechecking with retainFullTypeGraphs set to false); fixes https://github.com/Roblox/luau/issues/975 * `string.format` with %s is now ~2x faster on strings smaller than 100 characters Native code generation: * All VM side exits will block return to the native execution of the current function to preserve correctness * Fixed executable page allocation on Apple platforms when using hardened runtime * Added statistics for code generation (no. of functions compiler, memory used for different areas) * Fixed issue with function entry type checks performed more that once in some functions
