Continuous delivery every single day

It has taken 20 years as a professional programmer to get to this point, but I have finally taken the final step to continuous delivery. We’ve been practising continuous integration for well over a year now. It seemed a logical step to deploy the software automatically. When a process is done manually you tend to make a lot of mistakes. I did anyway. I’d run the database upgrade script before the new one had been installed and of course I would take a long time performing the upgrade.
