Changes 3.15.1:
* Added SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
Bug Fixes:
* Fix the VACUUM command so that it spills excess content to disk rather than \ 
holding everything in memory, and possible causing an out-of-memory error for \ 
larger database files. This fixes an issue introduced by version 3.15.0.
* Fix a case (present since 3.8.0 - 2013-08-26) where OR-connected terms in the \ 
ON clause of a LEFT JOIN might cause incorrect results.
* Fix a case where the use of row values in the ON clause of a LEFT JOIN might \ 
cause incorrect results.
