API changes/compatibility report for the Qt4 library

Qt is a cross-platform C++ application framework. Using Qt, you can develop applications and user interfaces once, and deploy them across many desktop and embedded operating systems without rewriting the source code. Qt is written in C++ and is fully object-oriented.
