What's new
----------

These releases are maintenance releases containing numerous bugfixes. The full
changelog is at:

* 2.9.21rc1

What's the schedule for future maintenance releases?
----------------------------------------------------

These release candidates are planned to become general availability releases
on Monday, 3 May 2021.

The next batch of release candidates will be two weeks after that, on
17 May 2021. This is one week early than our usual cadence, as this will allow
us to align our future releases for ansible 2.9, ansible-base 2.10, and
ansible-core 2.11.


Porting Help
------------

We've published a porting guide at
https://docs.ansible.com/ansible/devel/porting_guides/porting_guide_2.10.html
to help migrate your content to 2.10.


If you discover any errors or if any of your working playbooks break when you
upgrade to 2.10.9rc1, please use the following link to report the regression:

In your issue, be sure to mention the version that works and the one that
doesn't.

Thanks!
