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. +</blockquote><hr width="50%"><a name="2016_04_08"></a><h3>2016-04-08 - Release 3.12.1</h3><blockquote> +<p>SQLite <a href="releaselog/3_12_1.html">version 3.12.1</a> is an emergency patch release to address a + <a href="https://www.sqlite.org/src/info/7f7f8026eda38">crash bug</a> that snuck + into <a href="releaselog/3_12_0.html">version 3.12.0</a>.
