0.4.5

Release Notes

Released on 2026-06-15.

✨Highlights

0.4.5 completes prek's pre-commit language coverage. With R, Conda, Perl,
and coursier now supported, prek supports every language available in
pre-commit, plus prek-only modern languages such as Bun and Deno.

This is full feature parity with pre-commit. The last major compatibility gap
is closed, and prek is now on the path to 1.0.
