| 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. |
