+`1.0.0 <https://github.com/pytest-dev/pytest-asyncio/tree/1.0.0>`_ - 2025-05-26
+===============================================================================
+
+Removed
+-------
+
+- The deprecated *event_loop* fixture. (`#1106 <https://github.com/pytest-dev/pytest-asyncio/issues/1106>`_)
+
+
+Added
+-----
+
+- Prelimiary support for Python 3.14 (`#1025 <https://github.com/pytest-dev/pytest-asyncio/issues/1025>`_)
+
+
+Changed
+-------
+
+- Scoped event loops (e.g. module-scoped loops) are created once rather than per scope (e.g. per module). This reduces the number of fixtures and speeds up collection time, especially for large test suites. (`#1107 <https://github.com/pytest-dev/pytest-asyncio/issues/1107>`_)
+- The *loop_scope* argument to ``pytest.mark.asyncio`` no longer forces that a pytest Collector exists at the level of the specified scope. For example, a test function marked with ``pytest.mark.asyncio(loop_scope="class")`` no longer requires a class surrounding the test. This is consistent with the behavior of the *scope* argument to ``pytest_asyncio.fixture``. (`#1112 <https://github.com/pytest-dev/pytest-asyncio/issues/1112>`_)
+
+
+Fixed
+-----
+
+- An error caused when using pytest's `--setup-plan` option. (`#630 <https://github.com/pytest-dev/pytest-asyncio/issues/630>`_)
+- Unsuppressed import errors with pytest option ``--doctest-ignore-import-errors`` (`#797 <https://github.com/pytest-dev/pytest-asyncio/issues/797>`_)
+- A "fixture not found" error in connection with package-scoped loops (`#1052 <https://github.com/pytest-dev/pytest-asyncio/issues/1052>`_)
+
+
+Notes for Downstream Packagers
+------------------------------
+
+- Removed a test that had an ordering dependency on other tests. (`#1114 <https://github.com/pytest-dev/pytest-asyncio/issues/1114>`_)
+
+
 0.26.0 (2025-03-25)
