**New features:**
* [bugzillarest] API Key authentication\
A new authentication is available in the `bugzillarest` backend using
an API Key. This can be provided using the parameter `--api-key` on
the command line. Note that this parameter will invalidate `--backend-
user` `--backend-password`, and `--api-token` parameters. For
developers, this parameter is also available during the initialization
of the class `BugzillaRESTClient` under the name `api_key`.
* Confluence supports fetch by spaces\
This allows fetching confluence by specific spaces. By default it will
fetch the entire instance, but adding the `--spaces` argument will
fetch only these spaces.
**Feature removals:**
* Drop Python 3.6 support\
Python 3.6 reached the end of life at the end of 2021. This means it
won't receive new updates or patches to fix security issues.
Therefore, this package will only work with Python >= 3.7 from now on.
