Track Github repo releases and post to slack. This doesn't require Github tokens, as it scans through ATOM/RSS feeds. The slack post view needs a bit more work, as slack still doesn't support table formatting.
The updater.py checks for new releases in last 24hours based on the content of the configuration file and sends a notification via slack.
You would need to add a new environment variable called SLACK_WEBHOOK. Which will be your slack destination to post the messages.
