Please see my blog post at http://www.angrydonuts.com for some discussion of the new features across the Panels 3 Suite.

Please be absolutely certain that you upgrade CTools and Panels at the same time!!!!!

• Experimentally introduced the In-Place Editor (IPE).
• Updated Panels Stylizer to use CTools' new Export UI.
