+**31 improvements and bug fixes**
+
+* All controls now support the High Contrast mode when loading the application while in High Contrast mode.
+* In AvalonDock with Metro Dark accent theme, the resize splitter now uses a light color while dragging.
+* In AvalonDock, using the CacheDocumentTabItems/CacheAnchorableTabItems properties no longer creates a loading delay or removes the vertical scrollbar. Same thing in the ExtendedTabControl when using the CacheTabItems property.
+* In AvalonDock, a new event "ToggledPin" is now raised when a LayoutContent is pinned/unpinned.
+* In Chart, DataPoints with NaN coordinates can now be passed to a LineLayout series. These DataPoints won't be rendered in the chart, creating gaps between the valid DataPoints connections.
+* In MaterialHamburger, showing and hiding the MaterialHamburgerMenu contained in a UIElement, no longer clips the UIElement.
+* In MaterialHamburgerMenu with themes, a vertical scrollbar now appears when its content do not fit in the available space.
+* In ToggleSwitch and MaterialSwitch, the IsChecked property can now accept the null value, along with the usual true/false values.
+* In TokenizedTextBox, new overridable callbacks are now available(OnFilteredItemsChanged & OnCoerceFilteredItems) to manage the filtered items to be displayed in the popup.
+* In AvalonDock, pinning an auto-hide LayoutAnchorable now pins it on the appropriate side depending on its position in the children list.
+* In AvalonDock, creating and dropping a LayoutDocumentFloatingWindow now updates the remaining star sized LayoutElements.
+* In AvalonDock, resizing a star sized LayoutElement, which is part of a multi star sized pane, now keeps the proportional values. 
+* In AvalonDock, closing all floating windows now brings the focus back to the window containing the DockingManager.
+* In AvalonDock, the "X" button on a LayoutAcnhorableFloatingWindow now displays an "Hide All" tooltip, letting users know that all the floating LayoutAnchorables will be hidden on a click.
+* In AvalonDock, the method DockingManager.ShowNavigatorWindow is now "protected internal virtual", so it can be overriden in a derived DockingManager.
+* In AvalonDock, default texts are now localized for Japanese language.
+* In AvalonDock, Dynamically adding LayoutDocuments/LayoutAnchorables now displays the content of the newly added LayoutContent.
+* In AvalonDock, clicking on a label with a shortcut key no longer throws an InvalidCastException.
+* In AvalonDock, calling Float, Hide, Show and Dock (in that order) on a LayoutAnchorable now docks the LayoutAnchorable in the expected container.
+* In AvalonDock, hiding floating windows and reloading the layout no longer remove the focus from the DockingManager.
+* In CheckComboBox/CheckListBox, using a ValueMemberPath containing many parts (propA.propB.propC) now correctly updates the SelectedValue property. It also displays the first item selected in the TextBlock.
+* In CollectionControlDialog, using objects with cycling dependencies no longer throws StackOverflow exceptions.
+* In DateTimePicker, modifying the Value property more than once in code-behind (with different times) no longer keep the old time.
+* In DateTimePicker, DateTimeUpDown and TimePicker, when AllowTextInput is true, the "+" and "-" keys from the NumPad no longer increment/decrement the current value.
+* In DropDownButton and SplitButton, clicking on the arrow button when the popup is opened now closes the popup.
+* In Magnifier, setting the IsEnabled property to false now disables the Magnifier.
+* In MultiLineTextEditor, the default content is now a TextBlock, binding to the Text property with Text ellipsis.
+* In MultiLineTextEditor, disabling the control now grays out the text content.
+* In PropertyGrid, the PropertyItem's red invalid border is now displayed when a property is set to an invalid value from code-behind.
+* In RichTextBox, highlighting different portions of the text now displays the RichTextBoxFormatBar with the  corresponding values. 
+* In Wizard, when using a ShowDialog Window containing a Wizard, pressing the Wizard's cancel button and canceling the "cancel process" now only raises one OnClosing event.
