In the process of enhancing MySQL replication with new features for our users, we also improve the internals. A lot of work goes also to modernize the codebase and make it easier to maintain and obviously extend as well.

When joining a new server into a running replication group, a manual offline provisioning procedure was required in most cases as a tool to execute this step in the context of distributed recovery was missing.…
The MySQL Development Team is very excited and proud of what was achieved in this 8.0.17 GA release!
