Hello. We are in the middle of upgrading to Kotlin 2.1 and we ran into an issue with kotest 5.9 that forced us to try the 6.0 milestones. However, now I am seeing that IsolationMode.InstancePerLeaf has been removed. Is this expected? I couldn’t find anything in the changelogs. If its expected is there a “rough draft” of the guide for migration?
