AutoCompleteBox

• SelectedItem is now a settable property, enabling improved data binding.
• ValueMemberBinding is a new property of type Binding that can be used to set the binding used for determining the text value of a bound data object.
• Converter, ConverterParameter, ConverterCulture dependency properties have been removed, replaced by the single ValueMemberBinding property. Existing converters should easily work as the Converter property of the new binding property.

Theming

• Added 2 new themes: BubbleCreme & TwilightBlue
• Fixed bugs for the following themes: Expression, Rainier and Bureau
• Sample Theme Browser improvements to better highlight the themed controls.

TreeView

• Fixed issue where it was possible to get two items selected when setting selection state on TreeViewItems not yet expanded.
• Fixed issue where setting focus to the TreeView would cause the first item to become selected. (CodePlex issue 1360 with 17 votes and 1511, 5 votes).
• Fixed an edge case where attempting to scroll an item into view in a TreeView would give inconsistent results due to the wrong width values being used. (CodePlex issue 1583, 1 vote)

HierarchicalDataTemplate

• Has been moved to the System.Windows namespace.

Viewbox

• Fixed: Viewbox named child does not populate on InitializeComponent.

Calendar

• Fixed: ListBoxItem Accessibility: Browsers crash/restart when spying calendar that inside of a listbox
• Fixed: Under very rare circumstances it was possible to crash the browser when clicking on the Calendar. Issue was never reported by users, only discovered during stress tests.

DatePicker

• Fixed: DatePicker watermark text could get into an inconsistent state when date was set programmatically.
• Fixed: If the DatePicker is not the first control in a StackPanel, the Calendar stays open and covers other UI.
• Fixed: Under very rare circumstances it was possible to crash the browser when clicking on the DatePicker. Issue was never reported by users, only discovered during stress tests.

GridSplitter

• Fixed: GridSplitter default style has extraneous x:Key that Silverlight ignores but Blend considers invalid XAML.

TabControl

• Fixed: TabControl does not use ContentTemplate of tab items.

Charting Notable Changes

• Significant performance improvements to many parts of the Charting framework yielding noticeable speed-ups for scenarios dealing with large data sets.
• Added new Series type, AreaSeries, which is used just like LineSeries. The addition of AreaSeries means that we now support all of the major chart types offered by the top level of Excel's ribbon.
• Any Series can now use CategoryAxis as its independent value axis. Specifically, it is now possible to create a line chart with values on the vertical axis and categories (ex: Dogs, Cats, Fish) on the horizontal.
• Added Dependent/IndependentValuePath string properties to simplify the experience of binding to data object properties. Made these properties the defaults at design time due to their ease of use.
• Design-time enhancements for Blend, including default XAML for a newly dropped Chart, improved metadata, and a slightly improved workflow.
• Added Origin and ExtendRangeToOrigin properties to LinearAxis and DateTimeAxis to enable more scenarios where these axes are used for dependent values.
• Changed the types of the Chart.Series/Axis properties to improve the code- and design-time experience. When adding a new item to these collections, Blend now automatically filters the list and displays only valid types.
• ExtendRangeToOrigin not available on DateTimeAxis. We don’t support custom origins for DateTimeAxis…yet. We're not convinced anyone wants them. The IRangeAxis interface has a read-only Origin property which is null for DTA.
• Fixed a memory leak that could occur when a Chart was removed from the visual tree and had one or more Series with their ItemsSource properties set to an ObservableCollection<T> owned by the application.
• Improved the default Template of ScatterDataPoint to improve performance and provide more consistent behavior.
• Various architectural changes to improve the current and future programmability story for Charting.
• Various UI improvements and bug fixes for issues reported by customers or found internally.

Charting Breaking Changes

• Assembly name changed to System.Windows.Controls.DataVisualization.Toolkit.dll (part of a Toolkit-wide change)
• Namespace root changed to System.Windows.Controls.DataVisualization (part of a Toolkit-wide change)
• Switched AxisOrientation values from Horizontal/Vertical to X/Y for clarity and future-proofing.
• As a consequence of the above change adding more flexible axis support to Series, the Series's axis properties have been renamed to be more general (ex: IndependentRangeAxis -> IndependentAxis).
• Chart default template changes to make things a bit easier for designers to customize. New EdgePanel primitive makes this process more straightforward.
• Legend is now a TemplatePart of Chart; correspondingly its LegendItems property has been removed.
• Removed the MarkerWidth/MarkerHeight properties for Line/ScatterSeries; the defaults are now set by the default templates for Line/ScatterDataPoint and can be customized by re-Templating in the usual manner.
