<h2>SQLite Release 3.5.8 On 2008-04-16</h2><p><ol class='lessindent'>
<li>Expose SQLite's internal pseudo-random number generator (PRNG)
    via the <a href="../c3ref/randomness.html">sqlite3_randomness()</a> interface</li>
<li>New interface <a href="../c3ref/context_db_handle.html">sqlite3_context_db_handle()</a> that returns the
    <a href="../c3ref/sqlite3.html">database connection</a> handle that has invoked an application-defined
    SQL function.</li>
<li>New interface <a href="../c3ref/limit.html">sqlite3_limit()</a> allows size and length limits to be
    set on a per-connection basis and at run-time.</li>
<li>Improved crash-robustness: write the database page size into the rollback
    journal header.</li>
<li>Allow the <a href="../lang_vacuum.html">VACUUM</a> command to change the page size of a database file.</li>
<li>The xAccess() method of the VFS is allowed to return -1 to signal
    a memory allocation error.</li>
<li>Performance improvement: The OP_IdxDelete opcode uses unpacked records,
    obviating the need for one OP_MakeRecord opcode call for each index
    record deleted.</li>
<li>Performance improvement: Constant subexpressions are factored out of
    loops.</li>
<li>Performance improvement: Results of OP_Column are reused rather than
    issuing multiple OP_Column opcodes.</li>
<li>Fix a bug in the RTRIM collating sequence.</li>
<li>Fix a bug in the SQLITE_SECURE_DELETE option that was causing
    Firefox crashes.  Make arrangements to always test SQLITE_SECURE_DELETE
    prior to each release.</li>
<li>Other miscellaneous performance enhancements.</li>
<li>Other miscellaneous minor bug fixes.</li>
