pull-requests: add merge check that detects WIP marker in title. This will prevent merges in such case. Usually WIP in title means unfinished task that needs still some work. This pattern is present in Gitlab/Github and is already quite common.

Diffie-Hellman Security
-----------------------
To secure your web server, the `Guide to Deploying Diffie-Hellman for TLS`_
contains important information worth reading. This link contains some good
`secure Apache configuration`_ examples.
To secure your deployment of Diffie-Hellman, configure the following:
1. Generate a strong Diffie-hellman group, 2048-bit or stronger.
.. code-block:: bash
# to generate your dhparam.pem file, run in the terminal
openssl dhparam -out /etc/apache/ssl/dhparam.pem 2048
2. Configure your server to only use modern, secure cipher suites in the
virtual hosts configuration file.
.. code-block:: apache
# Set the protocol to only use modern, secure cipher suites.
SSLProtocol all -SSLv2 -SSLv3
