SQLite Release 3.8.5 On 2014-06-04
- Added support for partial sorting by index.
- Enhance the query planner so that it always prefers an index that uses a superset of
    WHERE clause terms relative to some other index.
- 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.
- Added the sqlite3_rtree_query_callback() interface to R-Tree extension
- Added new URI query parameters "nolock" and "immutable".
- Use less memory by not remembering CHECK constraints on read-only
    database connections.
- Enable the OR optimization for WITHOUT ROWID tables.
- 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 (?)"
- Add the ".system" and ".once" commands to the command-line shell.
- Added the SQLITE_IOCAP_IMMUTABLE bit to the set of bits that can be returned by
    the xDeviceCharacteristics method of a VFS.
- Added the SQLITE_TESTCTRL_BYTEORDER test control.

- Partial index causes assertion fault on UPDATE OR REPLACE.
    Ticket 2ea3e9fe63
- Crash when calling undocumented SQL function sqlite_rename_parent()
    with NULL parameters.
    Ticket 264b970c43
- ORDER BY ignored if the query has an identical GROUP BY.
    Ticket b75a9ca6b0
- The group_concat(x,'') SQL function returns NULL instead of an empty string
    when all inputs are empty strings.  
    Ticket 55746f9e65
- 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
- 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.
- 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.
- 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.
- SQLITE_SOURCE_ID: "2014-06-04 14:06:34 b1ed4f2a34ba66c29b130f8d13e9092758019212"
