You've been able to create a task list or a checkbox list in Outline for a while, but this week brings a nice improvement - we added task summaries so you can see how many tasks a doc contains and how many are completed without even opening it!
This is great for simple checklists such as new employee onboarding or a release checklist that you wouldn't neccesarily put in an issue tracker. You can also create repetitive task lists in templates.
The history sidebar was rebuilt to shows more than just edits, it now also includes archive, delete, publish, moves, and other events that happen during the document's lifetime.
You can find the new sidebar by clicking on the last edited timestamp or under "History" in the document menu.
