The main change in v3.0 was that we moved the custom statuses into tags. We thought that would be a good idea to automate the workflow and make use of the tags given it's agility. We did the migration but we didn't think it'll break anyone's workflow. That's why we didn't think that we should notify anyone before launching, and that was our mistake. We explained the logic behind the change after we launched but we should have done that before we launched.
