-------------------
- Added ``--all-sites`` option. This iterates over all sites and
performs the specified command on each of them. A failing command
for one site will stop the entire command. [maurits]
- Configure logging for the command line utility. By default print
only our own logging, on info level or higher. With the new
``--verbose`` option print all loggers (so also from other packages
like ``requests``) at debug level and higher. [maurits]
- Added ``plone_upgrade`` command to upgrade a Plone Site. This is
what you would manually do in the ``plone-upgrade`` view. [maurits]
- Added support for installing profiles. Profiles are only applied
once. Example command line: ``bin/upgrade install --site Plone
--profiles Products.PloneFormGen:default``. [maurits]
- Prevented UnicodeEncodeError when piping output of ``bin/upgrade
sites``. This would fail when a site had non-ascii characters in
its title. [maurits]
