IBM has put out the latest BPM Blueprint update today.? It isn't the most exciting update they've ever made to Blueprint, but of course I'd rather see incremental and frequent updates than one big overhaul for a service like this.? The August release seems to focus on adding avatars (aka pictures), and has a security model tweak, and a much-needed update to the Word export.
I'm still looking for more support for expert features (not necessarily their target audience yet, but I think the time has come to include more expert functionality in a tool that also appeals to more general collaboration).? Part of the reason I think this support is needed is so that users can import or export BPMN2 XML.? Not that the users will care that it is XML, but this is the modeling format that they're going to expect BPM tooling to support.
