Except for fine tuning, a new feature is here: Global settings (server settings) and Global roles.
This means that you don't have to configure your Deployify server on the host any more. All settings can be changed in Deployify with this new feature.
Deployify is now available for Docker on Ubuntu. If you are going to self-host Deployify server, this is the way to do it. Deployify for Docker has a feature that updates your Deployify server automatically.
