 ### Fixed
-* (runfiles) Fixed `CurrentRepository()` raising `ValueError` on Windows.
-  ([#3579](https://github.com/bazel-contrib/rules_python/issues/3579))
 * (tests) No more coverage warnings are being printed if there are no sources.
   ([#2762](https://github.com/bazel-contrib/rules_python/issues/2762))
 * (gazelle) Ancestor `conftest.py` files are added in addition to sibling `conftest.py`.
   ([#3497](https://github.com/bazel-contrib/rules_python/issues/3497)) Note
   that this behavior can be reverted to the pre-1.9.0 behavior by setting the new
   `python_include_ancestor_conftest` directive to `false`.
-* (pypi) `pip_parse` no longer silently drops PEP 508 URL-based requirements
-  (`pkg @ https://...`) when `extract_url_srcs=False` (the default for
-  `pip_repository`).
-* (pypi) Extras in requirement strings are now normalized per PEP 685,
-  fixing missing transitive dependencies when extras contain hyphens
-  (e.g., `sqlalchemy[postgresql-psycopg2binary]`).
-  ([#3587](https://github.com/bazel-contrib/rules_python/issues/3587))
 * (binaries/tests) Stamped build data generated by Windows actions is readable
