Please address the comments from this code review:
## Overall Comments
- Consider refactoring the tox env definitions to use factor notation or dynamic generation to avoid manual repetition for each DRF version.
- It might be worthwhile to expand your GitHub Actions matrix to run tests across multiple Python versions, not just 3.13, to catch compatibility issues earlier.
- Centralizing the supported DRF versions (e.g. reading from a single source or generating config entries) could reduce the risk of version list drift in config.py and build.ini.

Test data updated to reference version 3.9, but no tests for new versions 3.15 and 3.16.

Please add or update tests to cover versions 3.15 and 3.16 to ensure proper support and early detection of any issues.

Suggested implementation:

```python
        assert context['other_versions'] == ['3.9', '3.15', '3.16']

```

```python
        assert context['name'] == ListAPIView.__name__
        assert isinstance(context['ancestors'], (list, tuple))
        assert isinstance(context['direct_ancestors'], (list, tuple))

    def test_context_versions_315_316(self, get_template_mock):
        self.renderer.render('foo')
        context = get_template_mock.return_value.render.call_args_list[0][0][0]
        # Ensure 3.15 and 3.16 are present in other_versions
        assert '3.15' in context['other_versions']
        assert '3.16' in context['other_versions']

```

         self.renderer.render('foo')
         context = get_template_mock.return_value.render.call_args_list[0][0][0]
-        assert context['other_versions'] == ['3.2']
+        assert context['other_versions'] == ['3.9']
         assert context['name'] == ListAPIView.__name__

</code_context>

Assertion only checks for '3.9' in other_versions, missing coverage for all supported versions.

Parametrize the test or add assertions to verify that 'other_versions' contains all supported versions, not just '3.9'.

Suggested implementation:

```python
        expected_versions = ['3.9', VERSION]
        # Remove the current version from other_versions if present, as it's usually excluded
        expected_other_versions = [v for v in expected_versions if v != VERSION]
        assert sorted(context['other_versions']) == sorted(expected_other_versions)

```

If there are more supported versions, update `expected_versions` accordingly. If you want to parametrize the test for each version, consider using pytest's `@pytest.mark.parametrize` decorator and refactor the test to accept a version argument.
