Zero Downtime Deployment - I see the last 5 successful deployments, each of them with a Rollback button. However on the disk there are only 3 last deployments (as it is written in the documentation). I have no clue what will happen if I click on the 4th or 5th deployment's rollback button, but it's obviously impossible to rollback to physically not existent deployments so the button should be removed.

PS.: It rolled back successfully :) Have no idea which version in the reality.
