One request is to explicity explain the new mechanism so people don't have 
to read the diffs or extrapolate from the conversion scripts.

Please send a separate email with what API changes occured and include 
"API Change" in the subject so its pretty clear whats happening. Advance 
notice as to when it will be merged in is also a plus.

Thanks,
Tanya
