Has anyone begun testing 8.0.37 and have any updates on the MDL issue [PXC-4385] - Percona JIRA. Or stability or any other concerns with testing so far. We are just starting to upgrade are QA and Staging Clusters this week and MDL issue has been pretty serious for us.
We are continuing to perform testing, have not been to re-create the MDL issue on our smaller clusters, and have not yet found any new major problems yet. It would be really nice to get any feedback from any others who are testing the release in terms of any issues being seen and if it has resolved any of their other issues such as MDL, flow control etc. that were ticketed in the release notes.
