We just updated from 4.8.3 to 4.9.1, which included a change to PGP - it added a checkbox to "Use default naming for destination file". By default, this was turned on after the upgrade. Since we already had a number of jobs using PGP set up, it caused the existing jobs to fail, since they were not set up with that feature in mind.
When a new feature, such as this, is added, is it possible to prevent it from affecting existing jobs (or to leave it off by default if it is potentially disruptive to existing jobs)?
