Qt 2.0 Beta2 is not binary compatible with Beta1, this means that any
programs linked with Beta1 must be recompiled.
The most important fixes since Beta 1:
configure
Fixed the libzlib typo.
Added -lflags argument.
Platforms
Fixes for Borland C++, Solaris and AIX
QFileDialog
Several user interface improvements
QPrinter
Plain text printing works again.
Multiple page printing fixed.
QWidget
New widget flag WStyle_Dialog
Major changes since 1.4x:
The Qt version 2.x series is not binary compatible with the 1.x
series. This means programs compiled with Qt version 1.x must be
recompiled to work with Qt 2.0.
Qt 2.0 is mostly, but not completely, source compatible with Qt 1.x.
See the document "Porting from Qt 1.x to Qt 2.0" in the Online
Reference Documentation for information on how to port an existing
Qt 1.x-based program to Qt 2.0.
