This release adds full support for Qt v4.4.0 including the new QtHelp,
QtWebKit, QtXmlPatterns and phonon modules.

A Windows installer is provided for the GPL version of PyQt which contains

QScintilla) except Python itself.

PyQt is a comprehensive set of Qt bindings for the Python programming language
and supports the same platforms as Qt (Windows, Linux and MacOS/X). Like Qt,
PyQt is available under the GPL and a commercial license.

PyQt v4 supports Qt v4 (
PyQt v3 is still available to support earlier versions of Qt.

PyQt v4 is implemented as a set of 17 extension modules containing over 400
classes and over 6,000 functions and methods.

The non-GUI infrastructure including event loops, threads, i18n, Unicode,
signals and slots, user and application settings, mapped files and shared

A set of classes that allow the Qt Designer GUI design tool to be extended
with PyQt.

A rich collection of GUI widgets.

A set of classes for creating and viewing searchable documentation and
being able to integrate online help with PyQt applications. It includes
the C++ port of the Lucene text search engine.

A set of classes to support TCP and UDP socket programming and higher
level protocols (eg. HTTP, SSL).

A set of classes that allows PyOpenGL to render onto Qt widgets.

A set of classes that implements a JavaScript interpreter. Python objects
may be exposed in the interpreter as JavaScript objects.

A set of classes that implement SQL data models and interfaces to industry

A set of classes to render SVG files onto Qt widgets.

A set of classes to automate unit testing of PyQt applications and GUIs.
