• Improved: The control will clear its current text source when using set_controlToCheck/set_controlsToCheck client API methods

• Improved: RadSpell compatibility with other Telerik controls (RadEditor, RadComboBox, RadTextBox). No additional code needs to be added to the page when spell-checking a RadControl

• CDN support --Starting with the Q3 Service Pack 1 release you will be able to load the control scripts and skins from the Telerik CDN

• New Windows7 skin

• Added a LocalizationPath property (similar to editor and file explorer), which allows to load .resx files from any location in the web application

• Implemented automatic selection of server controls for the design time support of the ControlToCheck property of RadSpell

• Now using RadFormDecorator in the RadSpell dialog.

• Properly propagate all skin/scripts related properties to the dialog handler/window controls

• Added OnClientLoad property for RadSpell

• Added client boolean property useClassicDialogs for RadSpell - use spell.set_useClassicDialogs(true) to disable RadWindow dialog.

• Added a new property - ControlsToCheck. It allows checking multiple HTML elements without the need for custom client code.

• Added a new property - DialogsCssFile. It allows using custom skins with the spell dialog. Changed current dialog implementation to no longer use Default skin when EnableEmbeddedSkins is false.

• Added a new property – SpellCheckProviderTypeName. When set, the spell checker will use the custom provider instead of the default.

• Made the SpellCheckProvider base class public, so it will be possible to create custom spellchecking providers.
