SQLite Release 3.7.6 On 2011-04-12#

1. Added the sqlite3_wal_checkpoint_v2() interface and enhanced the wal_checkpoint pragma to support blocking checkpoints.
2. Improvements to the query planner so that it makes better estimates of plan costs and hence does a better job of choosing the right plan, especially when SQLITE_ENABLE_STAT2 is used.
3. Fix a bug which prevented deferred foreign key constraints from being enforced when sqlite3_finalize() was not called by one statement with a failed foreign key constraint prior to another statement with foreign key constraints running.
4. Integer arithmetic operations that would have resulted in overflow are now performed using floating-point instead.
5. Increased the version number on the VFS object to 3 and added new methods xSetSysCall, xGetSysCall, and xNextSysCall used for doing full-coverage testing.
6. Increase the maximum value of SQLITE_MAX_ATTACHED from 30 to 62 (though the default value remains at 10).
7. Enhancements to FTS4:
   1. Added the fts4aux table
   2. Added support for compressed FTS4 content
8. Enhance the ANALYZE command to support the name of an index as its argument, in order to analyze just that one index.
9. Added the "unix-excl" built-in VFS on unix and unix-like platforms.
10. SQLITE_SOURCE_ID: "2011-04-12 01:58:40 f9d43fa363d54beab6f45db005abac0a7c0c47a7"
11. SHA1 for sqlite3.c: f38df08547efae0ff4343da607b723f588bbd66b
