Prefect Community

Hi there.

I just had something strange happen on Prefect Cloud and was wondering why.

I have a flow that was running every night. Another person registered a new version of the flow (version 9). Until now, I had been the only person registering this flow.

Before the new flow version was registered, I could see the run history but once the new version got registered, I cannot see the history anymore. Also, I don't see the prior versions in the version drop down.

Hey <@U012CK03GBA>, I have been seeing some other users mention this. Will elevate to the team.

So there was an issue with the history retention logic that caused it to remove runs if the version `created_by` timestamp was outside of the history retention period. This will be fixed in the next hour or so to only take out a version if all of the runs are outside the retention period.

I can see the history now! Thanks for the fix.
