- type info as QString is now typeName() and setTypeName()
- added variant type (QVariant::Type) info: type(), setType()
- QgsFeature
- removed fields() - use QgsVectorDataProvider::fields()
- removed boundingBox() - use QgsGeometry::boundingBox()
- QgsVectorLayer - removed fields(), fieldCount(), getDefaultValue() - use directly QgsVectorDataProvider
- QgsVectorDataProvider - getDefaultValue() - field now addressed by id, returns variant
- QgsLabel - setLabelField() - field now addressed by id
