## SQLite Release 3.15.0 On 2016-10-14

- Added support for row values.
- Allow deterministic SQL functions in the WHERE clause of a partial index.
- Added the "modeof=filename" URI parameter on the unix VFS
- Added support for SQLITE_DBCONFIG_MAINDBNAME.
- Added the ability to VACUUM an ATTACH-ed database.
- Enhancements to the command-line shell:
  - Add the ".testcase" and ".check" dot-commands.
  - Added the --new option to the ".open" dot-command, causing any prior content in the database to be purged prior to opening.
- Enhance the fts5vocab virtual table to handle "ORDER BY term" efficiently.
- Miscellaneous micro-optimizations reduce CPU usage by more than 7% on common workloads. Most optimization in this release has been on the front-end (sqlite3_prepare_v2()).

  Bug Fixes:

- The multiply operator now correctly detects 64-bit integer overflow and promotes to floating point in all corner-cases. Fix for ticket 1ec41379c9c1e400.
- Correct handling of columns with redundant unique indexes when those columns are used on the LHS of an IN operator. Fix for ticket 0eab1ac759.
- Skip NULL entries on range queries in indexes on expressions. Fix for ticket 4baa46491212947.
- Ensure that the AUTOINCREMENT counters in the sqlite_sequence table are initialized doing "Xfer Optimization" on "INSERT ... SELECT" statements. Fix for ticket 7b3328086a5c116c.
- Make sure the ORDER BY LIMIT optimization (from check-in 559733b09e) works with IN operators on INTEGER PRIMARY KEYs. Fix for ticket 96c1454c
