 ### Fixed
+* (gazelle) `py_library` and `py_test` targets with missing source files are now
+  removed by Gazelle, matching the existing behavior for `py_binary` targets.
+  Previously, deleting a `.py` file in per-file generation mode left orphaned
+  targets in BUILD files, causing build failures
+  ([#3375](https://github.com/bazel-contrib/rules_python/issues/3375)).
 * (bootstrap) Fixed a potential race condition with symlink creation during
   startup.
 * (gazelle) Fixed handling of auto-included `__init__.py` files when generating `py_binary`
