New features and updates
- The list of SphinxQL reserved keywords is now much, much smaller than
it used to be, and also consistent across different places in the code
and in the docs.
- IN() function now accepts string attributes (#2233). Also, filtering
string attributes by an empty value in WHERE clause now works.
- WHERE on float attributes got improved a bit: we added floatcol<>123.0
syntax, and fixed an issue with using an integer reference value asi
in floatcol=123 or floatcol!=123, see bug #2121.
- searchd --replay-flags switch (useful for binlog replay troubleshooting)
now accepts a new option 'ignore-open-errors' that lets you simply
ignore missing binlog files without deleting binlog meta info.
- Indexer now exits with code 2 in case of rotation failure.
Notable bug fixes
- unified min_prefix_len, min_infix_len behavior between RT and plain indexes
- expressions dependent on aggregation results (eg. as in SELECT MAX(id) m1,
m1+10 m2) were not computed properly in RT indexes
- LENGTH() was 2x off for 64-bit MVA attributes
- OPTIMIZE could occasionally break big RT indexess
- multi-wordforms with clashing prefixes were processed in a wrong order
- disabled and later re-enabled indexes were not picked up again by searchd
on SIGHUP

Sphinx is an open source full text search server, designed from the ground up
with performance, relevance (aka search quality), and integration simplicity
in mind. Sphinx lets you either batch index and search data stored in an SQL
database, NoSQL storage, or just files quickly and easily - or index and
search data on the fly, working with Sphinx pretty much as with a database
server.
