Bleach is officially deprecated and no longer maintained as of its v6.4.0 release (see Mozilla's announcement). Since Bleach is an HTML sanitization library, using an unmaintained package poses a long-term security risk as new vulnerabilities will not be patched.

It is highly recommended to plan a migration to an actively maintained alternative, such as nh3 (Python bindings for the Rust-based ammonia HTML sanitizer).
