August 14, 2023 - See release notes at PMM 2.39.0 - Percona Monitoring and Management
Strange… Mine says up to date last checked today… Last check: August 16, 16:22 UTC Current version: 2.38.1 (July 11, 2023 UTC) I see the agents at 2.39.0 but I thought the install docs said make sure the server is the higher version Should a server version also be at 2.39.0?
you should be able to update your system via web.
Have you performed docker way update previously to get update from el7 to el9? If no - it is high time to do this as we do not provide el7 based builds any more
