The Curious Incident of the State Store in Recovery in ksqlDB

Hey there, I have a question relating to this Confluent blog post from August. It describes an issue we see with ksqldb0.7 when we scale down.

https://www.confluent.io/blog/ksqldb-state-stores-in-recovery/

It states:

Instead, we’ve implemented a patch that will help automatically resolve this in the future.

Can someone give me some guidance on which version of ksqldb has this patch as we’d like to upgrade but don’t want to do so blindly and find the patch is not in the release we are using?

Hey thanks! We’re really looking forward to upgrading to v 0.12 to get this and the automatic query restarting - ksqldb is looking very solid moving forward!
