| Qt 4.7.1 is a bug-fix release. It maintains both forward and backward |
| compatibility (source and binary) with Qt 4.7.0. For more details, |
| refer to the online documentation included in this distribution. The |
| documentation is also available online: |
| |
| http://qt.nokia.com/doc/4.7 |
| |
| The Qt version 4.7 series is binary compatible with the 4.6.x series. |
| Applications compiled for 4.6 will continue to run with 4.7. |
| |
| Some of the changes listed in this file include issue tracking numbers |
| corresponding to tasks in the Qt Bug Tracker, the (now obsolete) Task |
| Tracker, or the Merge Request queue of the public source repository. |
