Qt 4.6.1 is a bug-fix release. It maintains both forward and backward
|
|
compatibility (source and binary) with Qt 4.6.0. For more details,
|
|
refer to the online documentation included in this distribution. The
|
|
documentation is also available online:
|
|
|
|
http://qt.nokia.com/doc/4.6
|
|
|
|
The Qt version 4.6 series is binary compatible with the 4.5.x series.
|
|
Applications compiled for 4.5 will continue to run with 4.6.
|
|
|
|
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.
