User experience

This release includes the following enhancements to the user experience.

Area	Enhancement
Scripts	You can group scripts by Type and Author. This enables you to apply bulk updates, such as deletions, to particular groupings. For details, see Scripts.
Licenses	The latest allocation snapshot is now stored for each VU/VUH license, including expired licenses. This gives administrators visibility into how the license was recently allocated to projects, making it easy to reassign allocations after adding a new or renewed license. You can also export allocation details for active and inactive licenses. For details, see License allocation. Note: The system does not link new licenses to prior licenses, so snapshots are not carried over between licenses.
