- - QFileDialog::setDefaultSuffix() removes leading dot characters.
- - QSizePolicy got a retainSizeWhenHidden attribute.
- - [QTBUG-31602] QSpinBox size calculation will now be fixed when
-   stylesheets are used.
+ - [QTBUG-30255] Fixed a bug where spans across empty cells in a grid
+   layout got broken.
+ - [QTBUG-32788] Properly handles Qt::WidgetWithChildrenShortcut
+   shortcuts in MDI subwindows now.
+ - [QTBUG-33078] QWidget::setWindowOpacity() now works when called
+   before QWidget::show().
+ - [QTBUG-33247] Changed accessible trees and tables to always expose
+   hidden headers, instead of only exposing the visible headers.
+ - [QTBUG-34007] Fixed a crash in tablet support.
+ - Fixed a bug where the maximum size hint of a layout with spans was
+   wrong.
+ - Item delegates now cycle through all three states of tri-state
+   checkboxes, the same way QCheckBox itself does.
 
  - QAbstractItemView:
-   * [QTBUG-7232] QTBUG-7232 - In ItemViews scrollbars will now by default
-     only scroll 1 pixel when scrollMode is set to scrollPerPixel. That is
-     it will (when scrollMode is scrollPerPixel) do what is stated in the
-     documentation, and no longer automatically adjust the scrollbars
-     singleStep. The user can now control that value.
-
-  - QAbstractScrollArea:
-    * QAbstractScrollArea now has a SizeAdjustPolicy. If it is set to
-      AdjustToContents it will make use of the protected viewportSizeHint()
-      virtual function. This function returns a suggested size based on
-      contents. Note that although the viewportSizeHint() virtual function
-      was reserved in 5.0, user code was not supposed to be overriding it
-      (as the function was private and undocumented).  Code that was
-      overriding viewportSizeHint() needs to be recompiled against 5.2 for
-      this feature to work correctly.

+ - QColorDialog:
+   * Added a web color QLineEdit.
+   * [QTBUG-14332] Added a screen color picker button.
+   * [QTBUG-31998] Does no longer create widgets when using the
+     platform dialog.
+
+ - QComboBox:
+   * Added currentData() convenience function which allows to retrieve
+     the user data set for the current item.
+
+ - QCompleter:
+   * [QTBUG-3414] Added filterMode property.
+
+ - QDesktopWidget:
+   * [QTBUG-32567] Fixed emission of workAreaResized() signal.
+
+ - QDialogButtonBox:
+   * Added a (StandardButtons,QWidget*) constructor.
+
+ - QDockWidget:
+   * [QTBUG-31044] The position of a dock widget is now kept when
+     undocking.
+   * [QTBUG-32260] Fixed a bug where visibilityChanged was signaled
+     wrongly in certain multi-screen setups.
+
+ - QFileDialog:
+   * setDefaultSuffix() now removes leading dot characters.
+   * Introduced DontUseCustomDirectoryIcons. This improves the file
+     dialog performance under Windows for the case where there are
+     lots of folders. Went from taking 60 seconds to 2 seconds, on a
+     SDCard with 10k folders.
+   * Added setMimeTypeFilters() for mimetype-based filtering, as an
+     alternative to pattern matching.
+   * Fixed removing of directories containing hidden or system files.
+   * Added QUrl-based API for remote files.
+   * [QTBUG-13182] Improved performance on Windows by
+     + not resolving NTFS symlinks (15x speedup on pessimistic
+       workloads) and
+     + using extensions over calling GetFileAttributesEx() in certain
+       cases.
+   * [QTBUG-29403] Fixed potential crash in destructor of
+     ~QFileInfoGather in threaded applications.
+   * [QTBUG-34132] QFileDialog does no longer instantiate widgets if a
+     native dialog will be used instead.  Therefore some accessors
+     which previously returned unused objects will now return null.
+     As before, you can set the DontUseNativeDialog option to ensure
+     that widgets will be created and used instead.
+   * [QTBUG-33039] Does no longer create widgets when using the
+     platform dialog.
+
+ - QFontDialog:
+   * Now has finer-grained control over the types of fonts listed,
+     similar to what QFontComboBox already had.
+
+ - QGraphicsView etc
+   * Fixed a crash in QGraphicsProxyWidget.
+   * [QTBUG-8061] Allow handling of mouseDoubleClickEvent in
+     QGraphicsItems.
+   * [QTBUG-19036] Make QGraphicsScene::items(QPointF) work using
+     Qt::{Contains,Intersets}ItemBoundingRect with items that contain
+     the point in the bounding rectangle, but not their (custom)
+     shape.
 
  - QHeaderView:
    * [QTBUG-4346] A maximumSize for sections has been introduced. The
-     maximum section size is by default the largest possible section size
-     which in Qt 5.2 has been limited to 1048575 pixels.

+     (cf. displayIntegerBase property)

+     tooltip on Windows to what it was in Qt 4.
