Hi Marco

yes there are (will be) also other changes, mainly:
- QgsVectorLayer + QgsVectorDataProvider: select(), nextFeature(),
rewind(), featureAtId() replaced by getFeatures(), feature request and
feature iterator classes
- QgsFeature + QgsField: attributes are stored in a vector instead of
a map (for more efficient access).

That means everyone who does something with vectors is affected (c++
or python). At some point I will start preparing a porting guide.
