+===========
+
+Release Summary
+---------------
+
+| Release Date: 2021-05-17
+| `Porting Guide <https://docs.ansible.com/ansible/devel/porting_guides.html>`__
+
+
+Bugfixes
+--------
+
+- Correctly set template_path and template_fullpath for usage in template lookup and action plugins.
+- Fix fileglob bug where it could return different results for different order of parameters (https://github.com/ansible/ansible/issues/72873).
+- Improve resilience of ``ansible-galaxy collection`` by increasing the page size to make fewer requests overall and retrying queries with a jittered exponential backoff when rate limiting HTTP codes (520 and 429) occur. (https://github.com/ansible/ansible/issues/74191)
+- ansible-test - Use documented API to retrieve build information from Azure Pipelines.
+- ansible.builtin.cron - Keep non-empty crontabs, when removing cron jobs (https://github.com/ansible/ansible/pull/74497).
+- ansible_test - add constraint for ``MarkupSafe`` (https://github.com/ansible/ansible/pull/74666)
+- filter plugins - patch new versions of Jinja2 to prevent warnings/errors on renamed filter decorators (https://github.com/ansible/ansible/issues/74667)
+- service - compare version without LooseVersion API (https://github.com/ansible/ansible/issues/74488).
