I've merged the pending new features into master and updated the version to
0.27a0. Travis will need a while to give feedback if everything worked out,
but the PEPs 525, 530 (async generators/comprehensions) and 489 (module
initialisation) are now implemented in master. See my comments on them in
the changelog. I'd be happy to see some testing on user side.

Have fun!
