One of the most important issue for branch-2.3 is HBASE-21879, which means reading block offheap from fs to save GC. There's one remaining open issue which need to upgrade the Hadoop version to make the offheap reading really work, I will finish that issue in the next few days.
BTW, I was planing to be the branch-2.3 release manager but seems not enough time now, please ping me if anything I can help. Thanks for your volunteer, Nick.
