    Columns declared as <tt>"INTEGER" PRIMARY KEY</tt> (with quotes around

    [INTEGER PRIMARY KEY], which resulted in an incompatible database file.

<li>Fix a bug (present since [version 3.9.0]) that can cause the [DELETE]
    operation to miss rows if [PRAGMA reverse_unordered_selects] is turned on.
    Ticket [https://www.sqlite.org/src/info/a306e56ff68b8fa5|a306e56ff68b8fa5]
<li>Fix a bug in the code generator that can causes incorrect results if
    two or more [virtual tables] are joined and the virtual table used in
    outer loop of the join has an [IN operator] constraint.
<li>Correctly interpret negative "PRAGMA cache_size" values when determining
    the cache size used for sorting large amounts of data.

newsitem {2016-04-18} {Release 3.12.2} {
<p>Yikes!  The 3.12.0 and 3.12.1 releases contain a backwards compatibility bug!
   Tables that declare a column with type <tt>"INTEGER" PRIMARY KEY</tt>
   (where the datatype name INTEGER is quoted) generate an incompatible
   database file.  The mistake came about because the developers have never
   thought to put a typename in quotes before, and so there was no documentation 
   of that capability nor any tests.  (There are tests now, though, of course.)
   Instances of quoting the datatype name are probably infrequent in the wild,
   so we do not expect the impact of this bug to be too severe.
   Upgrading is still strongly recommended.
<p>Fixes for three other minor issues were included in this patch release.
   The other issues would have normally been deferred until the next scheduled
   release, but since a patch release is being issued anyhow, they might as
   well be included.
