As part of our on-going work to improve workflow we've removed the Sticky Stages feature and replaced it with a new workflow rule, "Add label when issue is closed".
We removed Sticky Stages because:
- Few customers used it.
- Customers found it confusing.
- It suffered from a number of hard to fix bugs.
You can enable its replacement workflow rule via Project Settings > Workflow > Automated Workflow Rules > When an issue is closed.
You might find the workflow rule useful for scenarios like adding a 'to-verify' or 'release-notes' label automatically after an issue is closed.
Next up, making the "To Do" stage optional!
