<h2>SQLite Release 3.5.9 On 2008-05-14</h2><p><ol class='lessindent'>
<li>Added <em>experimental</em>
support for the <a href="../pragma.html#pragma_journal_mode">journal_mode</a> PRAGMA and persistent journal.</li>
<li><a href="../pragma.html#pragma_journal_mode">Journal mode PERSIST</a> is the default behavior in
<a href="../pragma.html#pragma_locking_mode">exclusive locking mode</a>.</li>
<li>Fix a performance regression on LEFT JOIN (see ticket #3015)
that was mistakenly introduced in <a href="../releaselog/3_5_8.html">version 3.5.8</a>.</li>
<li>Performance enhancement: Reengineer the internal routines used
to interpret and render variable-length integers.</li>
<li>Fix a buffer-overrun problem in <a href="../c3ref/mprintf.html">sqlite3_mprintf()</a> which occurs
when a string without a zero-terminator is passed to "%.*s".</li>
<li>Always convert IEEE floating point NaN values into NULL during
processing. (Ticket #3060)</li>
<li>Make sure that when a connection blocks on a RESERVED lock that
it is able to continue after the lock is released. (Ticket #3093)</li>
<li>The "configure" scripts should now automatically configure Unix
systems for large file support. Improved error messages for
when large files are encountered and large file support is disabled.</li>
<li>Avoid cache pages leaks following disk-full or I/O errors</li>
<li>And, many more minor bug fixes and performance enhancements....</li>
</ol></p>
<p>A <a href="../changes.html">complete list of SQLite releases</a>
in a single page and a <a href="../chronology.html">chronology</a> are both also available.
A detailed history of every
check-in is available at
