2009 workflow changes

Does anyone know where I can find details on the changes inworkflows for 2009, specifically as it relates to ECN's?

I've done a ton of work with ECN's and I'm hoping I won't need toredo any work..however, if there is a more efficient way of doingthings, I'm all for it.

The notifications are a huge pain right now and I think they'vemade improvements but I haven't seen any specifics.

Thanks,!
