You can now connect multiple users to a single tasks, similarly as for documentation items previously.
You can use this feature e.g. when you have a large organization and need input from multiple units, or when you have e.g. a separate partner responsible for the technical implementation of a task, but your owner keeps the overall responsibility.
"Tasks you're participating in" will show up on the Taskbook for all users, but with a smaller emphasis than the tasks where you're the actual owner.
