 ## [Unreleased]
 
+### Fixed
+- Python bindings now support Python 3.9-3.13 with proper CI testing and abi3 wheels (#55)
+
 ### Performance
 - **Canonicalization optimization** — `ValidationContext` enables skipping redundant `canonicalize()` syscalls during path validation. Trusted-parent fast path (via `DirCache`) and symlink-free fast path eliminate ~17% CPU overhead in extraction hot path.
