### Fixed

* (gazelle) Remove `visibility` from `NonEmptyAttr`.
Now empty(have no `deps/main/srcs/imports` attr) `py_library/test/binary` rules will
be automatically deleted correctly. For example, if `python_generation_mode`
is set to package, when `__init__.py` is deleted, the `py_library` generated
for this package before will be deleted automatically.

### Added

## [0.32.2] - 2024-05-14
