Before we ship the new release, we should adjust the default settings for the new generations validations:

• ends on... validations should be set to Ignore for now
• has ended on... validations should be set to Hint for now

This is a little bit less aggressive from the perspective of adding potentially lots of markers to existing workspaces. We will publish a blog post and short videos in order to spread the word about these settings in addition to that to make users aware.
