+Qt 4.3.1 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 4.3.0.
+
+The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and
+4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to
+run with Qt 4.3.

+****************************************************************************
+
+General Improvements
+--------------------
+
+- Translations
+    * Updated the German translation to provide complete coverage of Qt.
+
+- QDBusView
+    * Added icons for Mac OS X and Windows.
+
+- Intel C++ Compiler for Linux
+    * Added support for version 10 of the compiler. See the Compiler
+      Notes documentation for known problems and work-arounds for this
+      compiler.
+    * Added linux-icc-32 mkspec, for building with the 32-bit compiler
+      on 64-bit hosts.
+
+Third party components
+----------------------
+
+- FreeType
+    * Security fix (CVE-2007-2754): Integer overflow in the
+      TT_Load_Simple_Glyph function in freetype 2.3.4 and earlier allows
+      remote authenticated users to execute arbitrary code via crafted BDF
+      fonts.
+
+- SQLite
+    * File descriptors are not inherited during spawn() anymore.
+
+Build System
+------------
+
+    * Fixed native builds on ARM architectures.

+    * [168974] Fixed problems with compilation that could occur when
+      QT3_SUPPORT and QT_NO_CURSOR were defined.
+
+- QComboBox
+    * [165130] Mac OS X only: Fixed bug that caused an editable combo box to
+      cut off list entries.

+      hide() had been called.
+
+- QFile
+   * [167217] Fixed regression that prevented the sequential bit from being

+      always returned as the transparent color in an overlay.
+    * [162143] Fixed a crash that could occur when calling renderPixmap()
+      with extremely large sizes. It now gracefully fails instead.

+      no longer cause a full viewport update when they are updated.
+
+- QGraphicsView
+    * [160828] Fixed bug in QGraphicsScene/View::render() which could cause

+      scroll bars are disabled (Qt::ScrollBarAlwaysOff).
+    * [163537] Scroll bar ranges are now correct also for styles with a
+      viewport frame only around the viewport itself (e.g., Motif and Mac
+      OS X style).
+    * [158245] Calling setScene(0) now recalculates the scroll bar ranges.

+      for the look-ups to complete.
+    * [167487] Fixed support for Unix platforms that allow IPv6 look-ups

+
+- QMainWindow
+    * [166004, 167651] Made the unified toolbar handle layout requests.
+    * Mac OS X only: Don't move the window's title bar when clicking on the
+      toolbar button.
+    * [164105] Made the unified toolbar handle showMaximized().
+    * [162555] Move OpenGL contexts when the toolbar button is pressed and
+      we are using the unified toolbar.
+    * [169063] Fixed a crash that could occur when setting a new menu bar

+      and QProcess::readAllStandardOutput() no longer clear any unget data
+      or buffered data.
+
+- QPixmap
