    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.
