SIP v6.0.2<br>
A minor bug fix release.<br>
<br>
PyQt-builder v1.9.0<br>
A minor feature release.<br>
<br>
PyQt v5.15.3<br>
This is a bug fix release. The wheels have been restructured so that the <br>
Qt libraries are in separate wheels (as they are with PyQt6). Also the <br>
QtNetworkAuth bindings are now in a separate PyQtNetworkAuth project.<br>
<br>
PyQt v6.0.2<br>
This is a bug fix release.<br>
