We have a change [1] out there which will remove pep8 and use pycodestyle in global requirements. For this change to be merged we need all dependent projects to use the same and check if they have any conflicts. We are waiting for [2] for hacking and [3] for tackerclient to be merged so that we can merge [1] into global requirements. Requesting the cores in the hacking and tacker group to have a look into this and help us move further. Feel free to reply or drop by #openstack-requirements if you have any questions. Thanks in advance.
