Igniters, It’s time to refresh this abandoned thread and finally rollout out all the changes appeared in 2.1.
In addition, recently donated Persistent Store got the green light [1] to become a part of the master branch (no one asked for extra time to dive into its details) and, personally, it’s absolutely fine to make it available in the nearest release. My proposal is to do the release by mid of July (closer to July 15th). Is there anyone who is ready to take over as a release manager creating the page like this [2] and handling all release related activities?
