We wanted our Blue Green and Canary releases to be simple to use and I think we have found the sweet spot between flexibility and ease of use. Today we are also rolling out Preview deployments to GA for all our customers.

Over the past few months, many of our Hetzner customers reached out to us with complains of deployment failures.
