+Highlights
+----------
+
+* :ghissue:`4291`: Introducing Nouveau (beta) a modern, from-the-ground-up
+ implementation of Lucene-based full-text search for CouchDB. 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. This continues
+ the 3.x closed-by-default design goal.
+
+* Many small small performance improvements, see Performance section // TODO
