+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 specific fixes only,
+for general 4.5.x changes go to:
+
+ http://qt.nokia.com/developer/changes/changes-4.5.0
+ http://qt.nokia.com/developer/changes/changes-4.5.1
+ http://qt.nokia.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://qt.nokia.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
+-----------
+
+- Input methods
+ * Added events to support opening and closing the virtual keyboard, called
+ software input panel in Qt.
+ * Added an option to QApplication to choose between single or double click
+ input panel activation.
+ * Added input method hints API to Qt. These can be used to instruct input methods
+ to only allow certain characters or tailor their appearance.
+ * Added Qt::ImAnchorPosition to support querying for selections through input
+ methods.
+ * Added QInputMethodEvent::Selection to support setting the selection through
+ input methods.
+
+- 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.
+
+- QtSql
+ * Implemented QtSql module with sqlite3 backend. For now backend is
+ provided only in binary format.
+
