New release candidates: ansible-core 2.11.0rc1, ansible-base 2.10.8rc1, ansible 2.9.20rc1, ansible 2.8.20rc1

Hi all- we're happy to announce the following release candidates:

  * ansible-core 2.11.0rc1
  * ansible-base 2.10.8rc1
  * ansible 2.9.20rc1
  * ansible 2.8.20rc1

Several notes:

* ansible 2.8.20rc1 and ansible 2.9.20rc1 both have numerous security fixes
  which address several modules logging sensitive data. This flaw has been
  assigned CVE-2021-3447. See the changelog (linked below) for more
  information.

* This is the final release cycle for ansible 2.8.z, which has received only
  security updates since the release of 2.10.0.

* This is the final *bugfix* release cycle for ansible 2.9.z. Ansible 2.9 now
  enters the security-only phase (after this release candidate goes to GA), and
  only security-critical updates will be shipped from that point forward.
