# Bleach 6.4.0 releases -- final release

**[Planet Python](https://daily.dev/sources/planetpython)** · 4 min read · 1 upvotes · 0 comments

## Summary

Bleach 6.4.0 has been released as the final version of the Python HTML sanitization library. The release includes two security fixes and a tinycss2 dependency fix. The maintainer explains the decision to end the project after 16 years: the underlying html5lib dependency is unmaintained, the project has been solo-maintained, and switching contexts has become unsustainable. Users are advised to migrate to justhtml (which provides a migration guide) or the browser Sanitizer API. The project ran from 2010 to 2026, with 64 releases, ~960 commits, and 80 contributors.
