We should do a better job of publishing this info, so sorry about that.  We're targeting Beta1 of 0.6 in two weeks.  I circulated a high-level feature list for 0.6 at JUDCon and neglected to post it here:

• Clustering and Distribution

• Remote Client API
• PicketLink integration
• Gateways : HTTP, JPA, RESTEasy

That list is accurate today with the exception of JPA, which will likely push to 0.7.  In addition to the above list, we've been busy on other fronts:

When 0.6 is Final (which should only be a few weeks after Beta1), I will publish details on what we expect in 0.7 and I'll also look to outline the remaining releases up to 1.0.
