Some possible bugs are fixed.
The logging and error output is optimized.

On {{CUSTOM_COMMIT_MSG}} we are now using the latest commit message.

It's now possible to mention your teammates with @mate.
You can also use the {{CUSTOM_GITHUB_ACTOR_AS_SLACK}} to get a direct @mention in slack.

To use this you have to add the optional slack_mention_mapping_file input which has a path to a mapping file.

More information in the readme.md.

Added emoji / unicode support.
Thanks to @FeinesFabi.

First release with a lightweight {{custom_placeholders}} feature written in purely JavaScript.
