We had initially planned to release CTP3 during MIX. However, we had to make some API changes to get it conformat to the .Net naming guidelines. We wanted to take this changes now so that the CTP3 and RTM bits don't diverge in their API. Current plans is to release end of this week.

 Here are the changes

  *  All classes related to Velocity are prefixed with DataCache . This makes it easier to look for Velocity classes in IntelliSense.

* The region parameter moves to the end to make it easy for overloading.  

Here's the list that I grabbed from the latest doc that will come with CTP3.

Name Change Overview: 

The following table provides a summary of the name changes that occurred in the "Velocity" API between CTP3 and the previous release. A new class, enumeration, and delegates for the cache notifications API are also listed.
