Several packages are blocking this effort, all have open bugs at [4], if you'd like some upstream involvement, go ahead and look at some, I won't be able to fix them all alone :)

I scanned through the list and found one (python-mccabe) where switching to 3.7.0b5 is likely to fix it, since it looks related to the docstring AST change that was just reverted (that late reversion is the reason we're making a 5th beta release).

The rest seemed to relate to async becoming a keyword, "raise StopIteration" now being converted to RuntimeError rather than being an alias for "return" in generator implementations, and the changes to the way deprecation warnings get handled (by default and in unittest), so those breakages are unfortunately intentional :(

Cheers,

Nick.
