We are pleased to announce that after many long hours of work Teiid 7.0 CR1 is available.
This candidate release refines our separation of the old connector API into light weight Translators and JCA components .
Text  and web service  integration has been redesigned from the ground up to simplify usage. Nearly all of SQL/XML 2003  support has been added, as well as XMLTABLE  and XMLQUERY  from SQL/XML 2006 which replace our old xml/relational logic and direct XQuery integration respectively.
See the examples for a Dynamic vdb that calls and processes REST and RPC webservices from the National Weather Service for getting started with some of the XML features.
Support for nested table references was added , which is a better alternative Teiid's procedural relational style queries. And finally the AdminShell now has both a command line and a graphical mode thanks to a redesign utilizing Groovy .
As you can see there is a lot of new and powerful features available. In details blogs, articles are coming soon. Check it out today - http://www.jboss.org/teiid/downloads.html
