In total 108 issues were resolved - including several important Teiid procedure and OData production issues.

Lots of great community feedback went into this release from the forums and with issues from Mark Addleman and team, Red Hatter Graeme Gillies, long time user Luca Gioppo, and others including several new faces.

Housekeeping as of late includes an on going overhaul of the examples/quickstarts and we've created new JIRA projects to track:
This will help keep the Teiid JIRAs as focused as possible - so don't hesitate to log issues as you find them with Teiid or any related component.

Also if you haven't seen it yet, we've pulled together a single Security Guide from documentation that was spread among the other guides.

Thanks and Happy Teiiding,
Steve and Ramesh
