Revision control
++ 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.
