 Subject: [sqlite-announce] Version 3.19.3 containing an important bug fix
 Date: Thu, 8 Jun 2017 11:57:54 -0400

 A bug in the auto_vacuum logic for SQLite versions 3.16.0 through 3.19.2
 can (rarely) lead to database corruption.  SQLite version 3.19.3 has just
 been released to fix this bug.

     https://sqlite.org/
     https://sqlite.org/download.html

 See https://www.sqlite.org/src/info/fda22108 for more information about
 the bug.  The problem can only arise on databases that have auto_vacuum
 enabled.  Nevertheless, all users are encouraged to update.  If you have
 database files that are in auto_vacuum mode, you should consider running
 VACUUM on those databases after updating, in order to clear any database
 inconsistencies that might have been introduced by this bug.
