Hello

As the charm-guide [1] explains, OpenStack, Ceph, OVN and supporting charms moved from a single stable charm (for each OpenStack component) that supported multiple OpenStack releases, to individual tracks that each targets a specific release [2]. The current Zed release also recently [6] became stable.

Today, we have (re)released updated individual charms to the ussuri/stable, victoria/stable and wallaby/stable tracks. These are derived from the stable 21.10 charms (that supported queens -> xena). We have also released the Ceph octopus/stable track to support ussuri and victoria, and the existing Ceph pacific (which was already stable) that supports wallaby (and xena). The full list of charms for the Xena, Victoria and Wallaby OpenStack systems, includiong Ceph, OVN, mysql8, hacluster, rabbitmq-server, vault and others can be seen in the docs at [3].

The ussuri, victoria, wallaby, and xena tracks have been designed to be upgradable from the 21.10 charms if you are running the associated OpenStack version, but please do read the docs [4] about how to go about upgrading charms. The relevant track (e.g. victoria/stable) is also able to upgrade from the previous version. Please again consult the docs [5] for upgrading advice.

This was a significant piece of work by all those involved, so many, many thanks to all who contributed and made this happen!

Thanks!
