CI is currently setup. Is the publishing part still missing and in which cases should it be triggered?

Uhm... actually not sure about that. The flow described in the electron builder project works excellent though.

I'm using it in netlify-menubar.

The functionality is as follows:

• whenever a push happens travis builds the artefacts
• if the version number defined in the package json is not a release on GitHub yet, CI will create a draft and upload the artifects
• you only have to hit publish on the releases panel

Auto-updates work automatically with artifacts on GitHub, too.
