Here is a list of (major) changes in Qt from 0.92 to 0.93.

Bug-fixes, optimizations and much improved documentation, of course.

There are not many changes in the API interface.

Here's a list of the most important changes.

-------

  setCursor(), restoreCursor() now uses a stack of cursors.

  quit() is now a slot.

  exit() replaces the old static quit() function.

    like this: QColor(320, 255, 240, QColor::Hsv)

  Compatible with old code.
