 Changelog
 =========
 
-0.21.0 (23-03-19)
-=================
+0.21.0 (2023-03-19)
+===================
 - Drop compatibility with pytest 6.1. Pytest-asyncio now depends on pytest 7.0 or newer.
 - pytest-asyncio cleans up any stale event loops when setting up and tearing down the
   event_loop fixture. This behavior has been deprecated and pytest-asyncio emits a
   DeprecationWarning when tearing down the event_loop fixture and current event loop
   has not been closed.
 
-0.20.3 (22-12-08)
-=================
+0.20.3 (2022-12-08)
+===================
 - Prevent DeprecationWarning to bubble up on CPython 3.10.9 and 3.11.1.

-0.20.2 (22-11-11)
-=================
+0.20.2 (2022-11-11)

 - Fixes an issue with async fixtures that are defined as methods on a test class not being rebound to the actual test instance. `#197 <https://github.com/pytest-dev/pytest-asyncio/issues/197>`_
 - Replaced usage of deprecated ``@pytest.mark.tryfirst`` with ``@pytest.hookimpl(tryfirst=True)`` `#438 <https://github.com/pytest-dev/pytest-asyncio/pull/438>`_
 
-0.20.1 (22-10-21)

-0.20.0 (22-10-21)
-=================
+0.20.0 (2022-10-21)
+===================
 - BREAKING: Removed *legacy* mode. If you're upgrading from v0.19 and you haven't configured ``asyncio_mode = legacy``, you can upgrade without taking any additional action. If you're upgrading from an earlier version or you have explicitly enabled *legacy* mode, you need to switch to *auto* or *strict* mode before upgrading to this version.
 - Deprecate use of pytest v6.
 - Fixed an issue which prevented fixture setup from being cached. `#404 <https://github.com/pytest-dev/pytest-asyncio/pull/404>`_
