 * Nothing yet
 
 ### Fixed
+* (bzlmod) correctly wire the {attr}`pip.parse.extra_pip_args` all the
+  way to {obj}`whl_library`. What is more we will pass the `extra_pip_args` to
+  {obj}`whl_library` for `sdist` distributions when using
+  {attr}`pip.parse.experimental_index_url`. See
+  [#2239](https://github.com/bazelbuild/rules_python/issues/2239).
 * (whl_filegroup): Provide per default also the `RECORD` file
 
 ### Added
