# pre-commit v4.5.0 — pre-commit v4.5.0

- Product: pre-commit (https://whatsnew.fyi/product/pre-commit)
- Vendor: pre-commit
- Date: 2025-11-22
- Version: v4.5.0
- Original notes: https://github.com/pre-commit/pre-commit/releases/tag/v4.5.0
- Permalink: https://whatsnew.fyi/product/pre-commit/releases/v4.5.0

What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.
