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.
