Listview: sectionExpression has been replaced by section.property, section.criteria
=============================================================================
The changes below are pre-4.6.0 release.
QML API Review
==============
The QML API is being reviewed. This file documents the changes.
Note that the changes are incremental, so a rename A->B for example may be followed
by another subsequent rename B->C, if later reviews override earlier reviews.
