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.
