(#2760) + +### Performance + +- Speed-up the new backtracking parser about 4X in general (enabled when + `--target-version` is set to 3.10 and higher). (#2728) +- _Black_ is now compiled with [mypyc](https://github.com/mypyc/mypyc) for an overall 2x + speed-up. 64-bit Windows, MacOS, and Linux (not including musl) are supported.
