"git push" logic changed?

As of the git development tree from last night, 'git push' seems to work a bit differently now.

When I do:
	$ git push parent
it responds with
	No refs given to be pushed.

This used to work before.
Now I have to do:
	$ git push --all parent
to get things to be pushed.

Or should I always be doing --all?

thanks,
