Dojo 1.2 was just released over at
www.dojotoolkit.org, and it's also available in Aptana Studio!

The Dojo 1.2 plugin for Aptana Studio provides code completion; code assist for Dojo Core, Dijit, and DojoX; sample code; project wizards; and more to support your Dojo development efforts.
The Dojo team is calling this their "sliced bread" release because each change or enhancement felt like the best thing since sliced bread. See for yourself what they've been up to in the
release notes, and then get started using Dojo 1.2 in Studio!
