Docking/MDI

• Improved the AdvancedTabControl tab layout logic when using shrink overflow to help ensure tabs fully fill the control extent.

• Updated when the DockingWindow.IsOpen property is changed during layout changes to more closely match the DockSite.WindowsOpened/WindowsClosed events.
• Fixed a bug where the DockSite.WindowsOpening/WindowsOpened events didn't fire when programmatically docking or floating a closed docking window in several scenarios.
• Fixed a bug where an AdvancedTabControl with left/right tab placement didn't always measure the tabs correctly.
• Fixed a bug caused by a previous update where tabs using shrink overflow might not fully render the tabs in a certain scenario.
• Fixed a bug where deserializing a layout containing a SplitContainer with no current visible children could incorrectly show a splitter.
• Fixed a bug where the StandardSwitcher allowed the selected window's header image to render at its default size instead of a fixed size.

Editors

• Added the AutoCompleteBox.SelectedItemChanged event.
• Added the AutoCompleteBox.InputMode property, which determines control usage behavior.
• Added a HasText property to the BrushEditBox and ColorEditBox controls, allowing the text portion of the edit box to be hidden for swatch-only display.

• Updated numeric edit boxes to support large incremental changes when holding Shift while pressing Up/Down or rotating the mouse wheel.
• Updated several numeric edit boxes to support custom format strings with semi-colon conditional format specifiers.
• Updated AutoCompleteBox to dispatch filter application after property changes, thereby ensuring all data-bound properties are updated when the filter executes.
• Updated the ColorPicker.Value property to be a nullable Color.
• Fixed a bug where setting DateTimeEditBox.Value to a DateTime that is out of range of the current calendar could throw an exception.

Grids

• Added the PropertyGrid.RequestRefresh method that can request that the property grid refreshes its contents.
• Added the PropertyDescriptorPropertyModel.PropertyDescriptor property.
• Updated PropertyDescriptorPropertyModel to watch for changes to non-value PropertyDescriptor properties like DisplayName when the descriptor implements INotifyPropertyChanged.

• Fixed a bug where using multiple TreeListView star-sized columns could result in the last column's right edge being cut off by a pixel.
• Fixed a bug where a tree node being edited wouldn't scroll into view.
• Fixed a bug where setting TreeListBox.RootItem to null while a filter is active would call into the filter with a null item reference.
• Fixed a bug where refreshing TreeListView items in code-behind could trigger extra layout cycles.
• Fixed a bug where resetting a PropertyGrid value wouldn't raise the PropertyGrid.PropertyValueChanged event.
• Fixed a bug where changing the PropertyModel.IsExpanded property wasn't properly updating the PropertyGrid in a certain scenario.

SyntaxEditor

• Added a new background that renders the search range when the search overlay pane is in Selection scope mode.
• Added the SyntaxEditor.HasSearchOverlayPaneKeyBindings property, which can be set to false when using external search UI to prevent access to the built-in search overlay pane.
• Added the ICompletionItemCollection.CreateBatch and AddRange methods, which when used to add completion items can dramatically improve item-adding performance. Updated all premium add-on completion providers to use the new methods.
• Added the SyntaxEditor.CanScrollPastDocumentEnd property back with a default of true. It should only be changed to false if the editors doesn't use multiple font families/sizes or intra-line adornments.
• Flipped the order of the Guides and Highlights adornment layers.
• Improved search overlay pane logic related to the selection scope range.

• Updated logic so that when changing the SyntaxEditor.IsVirtualSpaceAtLineEndEnabled property to false, a virtual selection will be moved to document offsets.
• Updated the 'Adornments 8 - Color Preview' QuickStart to render the adornments using a draw callback method instead of UIElements.
• Updated several static members on HtmlContentProvider to be methods that take a IHighlightingStyleRegistry parameter, thereby allowing the content provider to do highlighting style lookups in the same registry used by a target view.
• Updated the search overlay pane when opened to not auto-search for tabs that may surround a zero-length selection.
• Updated the search views to allow Ctrl+Enter to execute a Find All search operation when the Find textbox has focus and IsFindAllButtonVisible is true.
• Updated mouse wheel scrolling to still work when the related scrollbar is hidden. It is recommended to set SyntaxEditor.CanScrollPastDocumentEnd to false when hiding the vertical scrollbar.
• Updated the SyntaxEditor.PasteDragDrop event to fire for drops within the same control, so that the accepted operation can be forced to Copy if desired.
• Fixed a bug where collapsible region highlights didn't render in the correct vertical location in a certain scenario.
• Fixed a bug where using touch to make a selection wasn't working properly in all scenarios.
