Compiled wheels are not yet provided for Python 3.15, so performance may be slower than on existing Python versions. Wheels will be provided once Python 3.15 is later in its release cycle.

Use the `pytest_asyncio_loop_factories` hook instead. ([#1419](pytest-dev/pytest-asyncio#1419)) #### Added - Added the `pytest_asyncio_loop_factories` hook to parametrize asyncio tests with custom event loop factories. The hook returns a mapping of factory names to loop factories, and `pytest.mark.asyncio(loop_factories=[...])` selects a subset of configured factories per test. When a single factory is configured, test names are unchanged. Synchronous `@pytest_asyncio.fixture` functions now see the correct event loop when custom loop factories are configured, even when test code disrupts the current event loop (e.g., via `asyncio.run()` or `asyncio.set_event_loop(None)`). ([#1164](pytest-dev/pytest-asyncio#1164)) #### Changed - Improved the readability of the warning message that is displayed when `asyncio_default_fixture_loop_scope` is unset ([#1298](pytest-dev/pytest-asyncio#1298)) - Only import `asyncio.AbstractEventLoopPolicy` for type checking to avoid raising a DeprecationWarning. ([#1394](pytest-dev/pytest-asyncio#1394)) - Updated minimum supported pytest version to v8.4.0. ([#1397](pytest-dev/pytest-asyncio#1397)) #### Fixed - Fixed a `ResourceWarning: unclosed event loop` warning that could occur when a synchronous test called `asyncio.run()` or otherwise unset the current event loop after pytest-asyncio had run an async test or fixture. ([#724](pytest-dev/pytest-asyncio#724)) #### Notes for Downstream Packagers - Added dependency on `sphinx-tabs >= 3.5` to organize documentation examples into tabs. ([#1395](pytest-dev/pytest-asyncio#1395)) </details> <details> <summary>python-gitlab/python-gitlab (python-gitlab)</summary> ### [`v8.4.0`](https://github.com/python-gitlab/python-gitlab/blob/HEAD/CHANGELOG.md#v840-2026-05-28) [Compare Source](python-gitlab/python-gitlab@v8.3.0...v8.4.0) ##### Features - **const**: Add new Security Manager role ([`3738bb2`](python-gitlab/python-gitlab@3738bb2)) ##### Testing - **const**: Add tests for AccessLevel ([`2ab6d9f`](python-gitlab/python-gitlab@2ab6d9f)) </details> --- - [ ] If you want to rebase/retry this MR, check this box --- This MR has been generated by [Mend Renovate](https://github.com/renovatebot/renovate).
