commit cf64a04f05fed86cf04f3713da1efd230f8d7608 Author: Sven Eckelmann sven@narfation.org Date: Mon Nov 20 17:27:26 2017 +0100

batman-adv: Convert CHANGELOG to reStructuredText

The current format of the file is not well defined. The reStructuredText format (as used by other batman-adv related files) has the benefit that it is similar easy to read and write. And it allows other tools to parse the content of the file and convert it in a sensible way to a different file format.

Multiple git repository web-based management software also can directly render these files as properly formatted HTML output.
