newsitem {2013-04-12} {Release 3.7.16.2} {
  SQLite [version 3.7.16.2] fixes a long-standing flaw in the Windows
  OS interface that
  can result in database corruption under a rare race condition.
  See [http://www.sqlite.org/src/info/7ff3120e4f] for a full description
  of the problem.

  As far as we know, this bug has never been seen in the wild.  The
  problem was discovered by the SQLite developers while writing stress tests
  for a separate component of SQLite.  Those stress tests have not yet
  found any problems with the component they were intended to verify, but 
  they did find the bug which is the subject of this patch release.

  Other than updates to version numbers, the only difference between this
  release and 3.7.16.1 is a two-character change in a single identifier,
  which is contained in the windows-specific OS interface logic.  There 
  are no changes in this release (other than version numbers) for platforms
  other than Windows.
