Qt 4.3 introduces many new features as well as many improvements and
bugfixes over the 4.2.x series. For more details, see the online
documentation which is included in this distribution. The
documentation is also available at http://qt.nokia.com/doc/4.3
The Qt version 4.3 series is binary compatible with the 4.2.x series.
Applications compiled for 4.2 will continue to run with 4.3.
The Qtopia Core version 4.3 series is binary compatible with the 4.2.x
series except for some parts of the device handling API, as detailed
in Platform Specific Changes below.
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Task Tracker:
