The bleach library is officially deprecated and no longer maintained (see Bleach Issue #698). There will be no future releases, including for security issues. While upgrading to v6.4.0 addresses the immediate vulnerabilities (GHSA-8rfp-98v4-mmr6 and GHSA-gj48-438w-jh9v), it is highly recommended to plan a migration to an actively maintained alternative such as nh3 (Python binding to the Rust ammonia HTML sanitizer) to ensure long-term security.
