Run Now has been added to the Test Library screen. This allows you to run a single test, bypassing the creation of a test set. Since it is controlled by a security setting, you can decide if this suits your team or not.
Along with Run Now, you can link tests directly to a release.
On the Ad Hoc Detail reports, you can now select linked items. The report returns the standard field selection and filtering for the core entity, and will include some basic information for the selected linked items by type.
