Hi all, I made the following changes to the KIP: https://cwiki.apache.org/confluence/pages/diffpagesbyversion.action?pageId=173082256&selectedPageVersions=12&selectedPageVersions=11
Some of the highlights are: 1. Changed the field from IsUnclean to IsLeaderRecovering 2. Added a few more sentences explaining why this KIP is backward compatible and the interaction between the controller and the partition leaders when they are in different software versions. Thanks -José
