NEXT RELEASE

------------

Minor improvements and fixes.

New features/improvements:

* ``common`` role

  * Changed how the packages are installed in Python virtual

    environments used for performing pip requirements upgrade checks,

    making the process more reliable. The packages in those dedicated

    environments are now fully pinned, including system packages such

    as ``setuptools`` and ``pip`` itself.

  * Changed the pip requirements checks to now take into account

    unsafe packages as well (such as ``setuptools`` and ``pip``) if

    listed.
