Did I understand right?

If I want PyQt for pr1.3 with QT4.7 I have to install the package which is indicated for pr1.2 and PyQT4.6 which sometimes was linked to QT4.6.
But now the package provides also some features of PyQt4.8 which is linked to QT4.7.

Am I right?


And what is the package PyQt4.7 experimental for and how do I install it?
