Hello Release Team,

This is just a friendly reminder of the standing OpenStack feature freeze
exception and the above scheduling alignment for OpenStack Ussuri and Focal.

The standing FFe includes OpenStack packages and their direct dependencies
managed under the OpenStack umbrella. Additionally, as discussed previously
in this thread, the OpenStack Ussuri release is scheduled for approximately
3 weeks after the release of Ubuntu Focal.

We've already received a release team +1 on this schedule (previously on
this thread) so this is just a friendly reminder that we plan to move
forward with this schedule.

Regards,
Corey Bryant
