+## 0.8.7
+Released the fix (already on `master` since June 2026, but never published) for `ImportError: cannot import name 'packaging' from 'pkg_resources'` on newer `setuptools` (>=71), which broke every CLI invocation on Python 3.12+ once `setuptools` stopped re-exporting `packaging` through `pkg_resources`. `main.py` now imports `from packaging import version as packaging_version` directly, and `packaging` is declared explicitly in `install_requires` instead of being relied on transitively.
