1 Qt 2.0 Beta2 is not binary compatible with Beta1, this means that any

     2 programs linked with Beta1 must be recompiled.

     3 

     4 The most important fixes since Beta 1:

     5 

     6 configure

     7 	Fixed the libzlib typo.

     8 	Added -lflags argument.

     9 

    10 Platforms

    11 	Fixes for Borland C++, Solaris and AIX

    12 

    13 QFileDialog

    14 	Several user interface improvements

    15 

    16 QPrinter

    19

    22 

    23 

    24 Major changes since 1.4x:

    25 

    26 The Qt version 2.x series is not binary compatible with the 1.x

    27 series. This means programs compiled with Qt version 1.x must be

    28 recompiled to work with Qt 2.0.

    29 

    30 Qt 2.0 is mostly, but not completely, source compatible with Qt 1.x.

    31 See the document "Porting from Qt 1.x to Qt 2.0" in the Online

    32 Reference Documentation for information on how to port an existing

    33 Qt 1.x-based program to Qt 2.0.
