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,

|
|
documentation is also available online:
|

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
|
|
