## SQLite Release 3.8.5 On 2014-06-04

1. Added support for partial sorting by index.
2. Enhance the query planner so that it always prefers an index that uses a superset of WHERE clause terms relative to some other index.
3. Improvements to the automerge command of FTS4 to better control the index size for a full-text index that is subject to a large number of updates.
4. Added the sqlite3_rtree_query_callback() interface to R-Tree extension
5. Added new URI query parameters "nolock" and "immutable".
6. Use less memory by not remembering CHECK constraints on read-only database connections.
7. Enable the OR optimization for WITHOUT ROWID tables.
8. Render expressions of the form "x IN (?)" (with a single value in the list on the right-hand side of the IN operator) as if they where "x==?", Similarly optimize "x NOT IN (?)"
9. Add the ".system" and ".once" commands to the command-line shell.
10. Added the SQLITE_IOCAP_IMMUTABLE bit to the set of bits that can be returned by the xDeviceCharacteristics method of a VFS.
11. Added the SQLITE_TESTCTRL_BYTEORDER test control.

    Bug Fixes:

12. OFFSET clause ignored on queries without a FROM clause. Ticket 07d6a0453d
13. Assertion fault on queries involving expressions of the form "x IN (?)". Ticket e39d032577.
14. Incorrect column datatype reported. Ticket a8a0d2996a
15. Duplicate row returned on a query against a table with more than 16 indices, each on a separate column, and all used via OR-connected constraints. Ticket 10fb063b11
16. Partial index causes assertion fault on UPDATE OR REPLACE. Ticket 2ea3e9fe63
17. Crash when calling undocumented SQL function sqlite_rename_parent() with NULL parameters. Ticket 264b970c43
18. ORDER BY ignored if the query has an identical GROUP BY. Ticket b75a9ca6b0
19. The group_concat(x,'') SQL function returns NULL instead of an empty string when all inputs are empty strings. Ticket 55746f9e65
20. Fix a bug in the VDBE code generator that caused crashes when doing an INSERT INTO ... SELECT statement where the number of columns being inserted is larger than the number of columns in the destination table. Ticket e9654505cfd
21. Fix a problem in CSV import in the command-line shell where if the leftmost field of the first row in the CSV file was both zero bytes in size and unquoted no data would be imported.
22. Fix a problem in FTS4 where the left-most column that contained the notindexed column name as a prefix was not indexed rather than the column whose name matched exactly.
23. Fix the sqlite3_db_readonly() interface so that it returns true if the database is read-only due to the file format write version number being too large.
24. SQLITE_SOURCE_ID: "2014-06-04 14:06:34 b1ed4f2a34ba66c29b130f8d13e9092758019212"
25. SHA1 for sqlite3.c: 7bc194957238c61b1a47f301270286be5bc5208c
