Please test + this thoroughly and report back any issues you might find. + + - Installation instructions // TODO LINK + - Report a bug // TODO LINK + +* :ghissue:`4570`, :ghissue:`4578`, :ghissue:`4576`: Adopt xxHash in favour + of md5 for ``couch_file`` checksums and ETag calculation. 30% performance + increase for large (128K) docs. No difference for smaller docs. + +* :ghissue:`4814`: Introduce PBKDF2-SHA256 for password hashing. The existing + PBKDF2-SHA1 variant is now deprecated. Increases the default iteration count + to ``500000``. Also introduce a password hash in-memory cache with a low + iteration number, to keep interactive requests fast for a fixed time. + + Entries in the password hash cache are time-limited, unused entries are + automatically deleted, and there is a capacity bound. + +* :ghissue:`4512`: Mango: add keys-only covering indexes. Improves query + response times for certain queries up to 10x at p(95). + +* :ghissue:`4681`: Introduce optional countermeasures as we run out of + disk space. + +* :ghissue:`4847`: Require auth for ``_replicate`` endpiont.

Comment: The rendering is broken here, I think it's because of the confusion with the backticks. It needs a backtick to close the ghissue stanza, then a separate set of double backticks to start the `_design_doc...` bit. -- This is an automated message from the Apache Git Service.
