Silverlight Studio 2012.2 build 141 has been released and is now available for download.  Several very nice new controls and enhancements are part of this build.

This build has the following major new features:

• SyntaxEditor: Added a NavigableSymbolSelector.AreRootSymbolsSupported property, that can be set to false to only show the member drop-down.
• SyntaxEditor: Added new SyntaxEditor.HorizontalScrollBarVisibilty and VerticalScrollBarVisibility properties that can be set to Hidden to hide scrollbars.
• SyntaxEditor LL(*) Parser Framework: Added a new Grammar.AstLeftAssociativity tree constructor method that can provide left associativity on binary operator expressions.
• SyntaxEditor .NET Languages Add-on: Improved the parser and resolver.

See the announcement post for the detailed list of enhancements and updates.
