    2 The Qt version 2.x series is not binary compatible with the 1.x
    3 series. This means programs compiled with Qt version 1.x must be
    4 recompiled to work with Qt 2.0.
    5 
    6 Qt 2.0 is mostly, but not completely, source compatible with Qt 1.x.
    7 See the document "Porting from Qt 1.x to Qt 2.0" in the Online
    8 Reference Documentation for information on how to port an existing
    9 Qt 1.x-based program to Qt 2.0.
