hbase-2.0.0-beta-2 is our second beta release. It includes all that was in previous alphas
and the previous beta (new assignment manager, offheap read/write path, in-memory
compactions, etc.).

hbase-2.0.0-beta-2 is a not-for-production preview of hbase-2.0.0. It is meant for devs and downstreamers to test drive and flag us if we messed up on anything ahead of our rolling
2.0.0 release candidates ("GAs").

The list of features addressed in 2.0.0 so far can be found here [3]. There are thousands.
The list of ~2k+ fixes in 2.0.0 exclusively can be found here [4].

I've updated our overview doc. on the state of 2.0.0 [6]. Next up are actual 2.0.0 release
candidates. Look for them in a week or so after we do up a bit more doc and test. Here is
the list of what is outstanding against 2.0.0 [5]. Only blockers will hold up release.

One known issue is that the User API has not been properly filtered so it shows more than
just InterfaceAudience Public content (HBASE-19663, to be fixed).
