SQLite Release 3.16.0 On 2017-01-02

Uses 9% fewer CPU cycles. (See the CPU performance measurement report for \ 
details on how the this performance increase was computed.)
Added experimental support for PRAGMA functions.
Added the SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE option to sqlite3_db_config().
Enhance the date and time functions so that the 'unixepoch' modifier works for \ 
the full span of supported dates.
Changed the default configuration of the lookaside memory allocator from 500 \ 
slots of 128 bytes each into 125 slots of 512 bytes each.
Enhanced "WHERE x NOT NULL" partial indexes so that they are usable if \ 
the "x" column appears in a LIKE or GLOB operator.
Enhanced sqlite3_interrupt() so that it interrupts checkpoint operations that \ 
are in process.
Enhanced the LIKE and GLOB matching algorithm to be faster for cases when the \ 
pattern contains multiple wildcards.
Added the SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
Added ".mode quote" to the command-line shell.
Added ".lint fkey-indexes" to the command-line shell.
Added the .imposter dot-command to the command-line shell.
Added the remember(V,PTR) SQL function as a loadable extension.
Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE to \ 
better reflect the implications of using it.

Bug Fixes:
Fix a long-standing bug in the query planner that caused incorrect results on a \ 
LEFT JOIN where the left-hand table is a subquery and the join constraint is a \ 
bare column name coming from the left-hand subquery. Ticket 2df0107b.
Correctly handle the integer literal -0x8000000000000000 in the query planner.
