Hi,

For a new PS operator we need to support mysql >= 8.0.26. Unfortunately orchestrator does not support it right now and we are going to create PR for upstream but as you know it can never be merged or it can take a lot of time.

So, for now we need to be able to use new plugins (semisync_source.so/semisync_replica.so) which were introduced in mysql 8.0.26. Could you please apply the patch 

(you can find it in the attachment) and build the packages and push them into testing repo.  P.S. you can start from el8 as you know our docker images are based on it.
