FREE SOFTWARE --
SQLite 3.15.0 is now available as the latest feature release of this widely-used, embed-able SQL database library.

The big feature addition of SQLite 3.15 is support for "row values", which is an ordered list of two or more scalar values -- basically, vectors. Row values are explained and demonstrated here.

SQLite 3.15 also now allows deterministic SQL functions in WHERE clauses of a partial index, support for SQLITE_DBCONFIG_MAINDBNAME, support to VACUUM an ATTACH-ed database, and various enhancements to the SQLite command-line shell.

Also exciting are various micro-optimizations to SQLite 3.15 for reducing CPU usage. SQLite developers indicate CPU usage is reduced by more than 7% with common workloads. As usual, there are also many bug-fixes.

More details on SQLite 3.15.0 via the release announcement.
