It keeps backward binary compatibility +with Qt 2.1 and both forward and backward source compatibility with Qt 2.2.x. + +Qt 2.2.0 had a binary compatibility problem with the following: + + bool QRect::contains( const QRect &r, bool proper=FALSE ) const + +Qt 2.2.1 corrects this. Programs compiled with 2.1.x now continue +running with 2.2.1. Programs compiled with versions other than 2.2.0 +may not run with 2.2.0, so upgrading to 2.2.1 is additionally important. + + +**************************************************************************** +* General * +**************************************************************************** + +- Various compilation problems on particular platforms fixed + +- Many improvments in QThread.

This shows great effect in the designer, were you usually +operate on container subwidgets in the design phase, but get a +complete layout in the preview mode or the generated code. For +example, the influence of a spacer item on a sublayout's size policy +has been reduced.
