Requirements

In order to add or change a Python dependency requirement of an OpenStack project, it must first be added to the openstack/requirements repository.

Add it to the 'test-requires' or 'pip-requires' files as appropriate and submit it for review.

The requirement specification should usually include both a lower and upper bound. The lower bound should reflect the oldest known version of the package which has the APIs required. An upper bound should be added based on a package's policy of release versioning with respect to incompatible API changes so that we avoid problems caused a future incompatible release.

Once the change to openstack/requirements has merged, the local pypi mirror will be updated and then the requirements file for the OpenStack project may be updated. The new requirement specification must match exactly what is in openstack/requirements.
