Changes 4.8.1:
* Support for the QT_BEGIN_NAMESPACE and QT_END_NAMESPACE macros to allow
  PyQt to be built against Qt built with namespace support.
* Bug fixes.

Changes 4.8:
* Added support for Qt v4.7 including the new QtDeclarative module.
* pyqtProperty() can now be used as a method decorator in the same way that
  the standard Python property type can be used.
* Added the notify argument to pyqtProperty().
* Unbound signals can now be subscripted in the same way that bound signals
  can.
* Added the missing << operator to QPolygon, QPolygonF and
  QXmlStreamAttributes.
* PyQt will now automatically keep a reference to objects set with some sort
  of setter method when Qt expects the underlying C++ instance to stay valid
  but does not take ownership of it.
* Added the lightmaps.py and stardelegate.py examples from Hans-Peter Jansen.
* Added the --assume-shared option to configure.py.
* The QtAssistant module is no longer built with Qt v4.7 and later.
