The release can be considered stable, and is in use behind several high traffic, public websites. It has been marked as a CTP release as it is not yet considered feature complete for a v1.0 release.
Bugs should be logged via the CodePlex Issue Tracker. Questions should be raised on the mailing list.
New in this release:
- Unity integration.
- Performance fixes. (N^2 presenters were being created when N instances of the same control and binding were placed on a page.)
- A more complete fix for issue 5737.
