<h2>SQLite Release 3.5.7 On 2008-03-17</h2><p><ol class='lessindent'>
<li>Fix a bug (ticket #2927) in the register allocation for
compound selects - introduced by the new VM code in version 3.5.5.</li>
<li>ALTER TABLE uses double-quotes instead of single-quotes for quoting
filenames.</li>
<li>Use the WHERE clause to reduce the size of a materialized VIEW in
an UPDATE or DELETE statement. (Optimization)</li>
<li>Do not apply the flattening optimization if the outer query is an
aggregate and the inner query contains ORDER BY. (Ticket #2943)</li>
<li>Additional OS/2 updates</li>
<li>Added an experimental power-of-two, first-fit memory allocator.</li>
<li>Remove all instances of sprintf() from the code</li>
<li>Accept "Z" as the zulu timezone at the end of date strings</li>
<li>Fix a bug in the LIKE optimizer that occurs when the last character
before the first wildcard is an upper-case "Z"</li>
<li>Added the "bitvec" object for keeping track of which pages have
been journalled. Improves speed and reduces memory consumption, especially
for large database files.</li>
<li>Get the SQLITE_ENABLE_LOCKING_STYLE macro working again on Mac OS X.</li>
<li>Store the statement journal in the temporary file directory instead of
collocated with the database file.</li>
<li>Many improvements and cleanups to the configure script</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
