SQLite Release 3.7.0 On 2010-07-21
-  Added support for write-ahead logging.
-  Query planner enhancement - automatic transient indices are created
     when doing so reduces the estimated query time.
-  Query planner enhancement - the ORDER BY becomes a no-op if the query
     also contains a GROUP BY clause that forces the correct output order.
-  Add the SQLITE_DBSTATUS_CACHE_USED verb for sqlite3_db_status().
-  The logical database size is now stored in the database header so that
     bytes can be appended to the end of the database file without corrupting
     it and so that SQLite will work correctly on systems that lack support
     for ftruncate().
