Beyond fixes several issues, this new build also provides a new set of features:

• A new redirect control that is used by the teamroom template, to redirect request coming from a mobile device
• A new LPTA based endpoint to manage single sign-on between Domino and Connections in the social enabler. Thanks to Reed Gesteland for his contribution
• A new value picker option to allow full text search based retrieval of values

The list is in the readme.pdf.

Enjoy!
