Hello, I received the long awaited 1390 release but I could use a little clarification on a paragraph in the technical bulletin

These releases bring
support for InfoPath and SharePoint 2010 Service Pack 1, performance and
stability enhancements, and for K2 blackpearl the ability to integrate with
SharePoint 2010 claims-based sites. 

Is claims support limited to blackpearl? For months I've been assured by K2 staff at conferences and in support calls that the next update to blackpoint would support claims, but this seems to indicate otherwise. I've installed the update on a claims environment and I'm getting errors in the My Tasks webpart that the SAML token could not be verified.
