Changes 3.7.14:
* Drop built-in support for OS/2. If you need to upgrade an OS/2 application to
  use this or a later version of SQLite, then add an application-defined VFS
  using the sqlite3_vfs_register() interface. The code removed in this release
  can serve as a baseline for the application-defined VFS.
* Ensure that floating point values are preserved exactly when reconstructing a
  database from the output of the ".dump" command of the command-line shell.
* Added the sqlite3_close_v2() interface.
* Updated the command-line shell so that it can be built using
  SQLITE_OMIT_FLOATING_POINT and SQLITE_OMIT_AUTOINIT.
* Improvements to the windows makefiles and build processes.
* Enhancements to PRAGMA integrity_check and PRAGMA quick_check so that they
  can optionally check just a single attached database instead of all attached
  databases.
* Enhancements to WAL mode processing that ensure that at least one valid
  read-mark is available at all times, so that read-only processes can always
  read the database.
* Performance enhancements in the sorter used by ORDER BY and CREATE INDEX.
* Added the SQLITE_DISABLE_FTS4_DEFERRED compile-time option.
* Better handling of aggregate queries where the aggregate functions are
  contained within subqueries.
* Enhance the query planner so that it will try to use a covering index on
  queries that make use of or optimization.
