 ### Redesign of the Relations tab in work packages
 
+The Relations tab in work packages has been completely redesigned, including a **new dropdown menu that allows you to directly choose the type of relation**, e.g. if the related work packages is a successor and necessarily needs to start after the selected one finishes. Additionally, you can now add a description to add further information about the relation. Please note that the description will be desplayed on both work packages, below the related other work package.

+> Important information: With this redesign, **you will no longer be able to create new work packages directly on the Relations tab**. Please tell us if you were using this feature a lot. If it will be missed by many users, we will find a way to bring it back.
