+<ul>
+ <li>The analyzer is now far more aggressive with checking conformance with Core Foundation conventions. Any function that returns a CF type must now obey the Core Foundation naming conventions, or use the <a href="/annotations.html#attr_cf_returns_retained">cf_returns_retained</a> or <a href="/annotations.html#attr_cf_returns_not_retained">cf_returns_not_retained</a> annotations.</li>
+ <li>Fixed a serious regression where the analyzer would not analyze Objective-C methods in class extensions.</li>
+ <li>Misc. bug fixes to improve analyzer precision.
+ </li>
