Hi Bruno,

thanks for all the work on pytest-2.8 and the release!

Was wondering -- did you conciously choose to not re-create and install
docs before releasing? 

FWIW I just regen'ed docs and pointed pytest.org/latest to 2.8 (it previously
had "latest" point to 2.7).  The regen did not run fully to the end
so some examples have not been regenerated yet but it's better than having
a fully outdated doc version i think.  Maybe ronny could take a look why
"tox -e regen" chokes?
