Qt 4.5.2-tower
---------------
The Qt for S60 "Tower" release is the fifth pre-release from the Qt for
S60 porting project. "Tower" is based on the Qt 4.5 codebase (mostly Qt 4.5.2).
This list of changes lists S60 spesific fixes,
for general 4.5.x changes go to:
http://www.qtsoftware.com/developer/changes/changes-4.5.0
http://www.qtsoftware.com/developer/changes/changes-4.5.1
http://www.qtsoftware.com/developer/changes/changes-4.5.2 (partially in Tower)
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Task Tracker:
http://qtsoftware.com/developer/task-tracker
Each of these identifiers can be entered in the task tracker to obtain
more information about a particular change. Sometimes the task is internal
and cannot be viewed by the public, a lot of them are non-public for Qt for
S60 at the moment.
****************************************************************************
* New features *
****************************************************************************
New modules
-----------
- QtSql
* Implemented QtSql module with sqlite3 backend. For now backend is
provided only in binary format.
- QtWebkit
* Experimental webkit build for S60. Can be enabled by passing -webkit to configure.
- Phonon
* The Phonon library is now part of Qt, but it comes without a backend.
This means that applications can build and run against the Phonon
library, but there is currently no S60 backend plugin providing actual
multimedia playback. Possible alternatives such as Helix and MMF are
being investigated.

* Implemented CMdaAudioPlayerUtility based Symbian backend for QSound.

* Plugins *
****************************************************************************
