Version 0.2.0

The alert messages can now be customized by providing custom templates using the -text-template and -html-template flags.
The built-in default templates can be found in the documentation. The icons and colors now define the behaviour of the built-in icon and color templating functions, and they can be configured by providing a YAML file using -icon-file and -color-file respectively. Note that old JSON files should still work as JSON is valid YAML. See the documentation for the (unchanged) default values.

The underlying framework now uses matrix-bot for interaction with Matrix. This somewhat changes the interaction with the bot from Matrix (in a good way!).

Lastly, the project now uses the latest version of github.com/prometheus/alertmanager, including its parsing functions.

The latest builds (including vendored sources and RPM packages) can be downloaded from GitLab.
