     * [258526] Rotate the image if the tiff file contains an orientation tag.
     * [254317] Add support for mono and indexed format
 
+ - QPlainTextEdit
+    * Fixed crash when clicking on a text edit which was smaller than the 
+      height of the font used.
+	  
+ - QPrinter 
+    * [QTBUG-4497] Removed redundant SetPen command in the postscript code 
+      when reusing a QPrinter object.
+
+ - QTextLayout
+    * [QTBUG-4468] Count tabs as multiple characters when applying a fixed
+      column width.
+	* [176401] Take into account the negative right bearing of the last 
+      character in an item of text if the glyph extends beyond its ascent.
+	
+ - QTextDocument
+    * [207189] Support setting font size using short hand syntax in the 
+      CSS "font" property.
+	* [201228] Remove implicit margin on bullet lists when exporting to 
+      HTML.
+	* [240086] Fixed bug which caused floating objects which span several
+      pages to float into the second page of the document even when it's
+      the only existing object, causing the document to contain a blank
+      first page.
+	* [240325] Even when wrap mode is set to Qt::TextWordWrap, the layout
+      would sometimes break outside word boundaries when floating objects
+      affected the width available to the text. This has been fixed.
+ 
+ - QFontEngine 
+    * [QTBUG-2354] Support certain 'Microsoft' platform symbol fonts which 
+      also contain a regular unicode table for exactly the symbol range of
+      code points.
+	  
+ - QFontMetrics	  
+    * [176401] Account for right bearing in bounding rect.

  - Compilation fixes for OpenGL/ES 1.0 and OpenGL/ES 1.1 Common Lite.

  - EGL and OpenGL/ES
    * Protect the use of version-specific EGL symbols with #ifdef's.
    * Make sure an EGL context is current when resolving GL extensions.
