See the Version 2.4 Feature Overview Video article for a video introduction to some of these new features.
New Features
Assessment Management
A number of new features make it easier to manage assessments, including the ability to:
- Delete unused data definitions;
- Modify any fields currently used in an assessment;
- Select a new data definition for an unlaunched assessment;
- Delete a launched assessment type and all its data; and
- Delete an individual assessment object and its instances (evaluations).
Note that only administrators with Delete permissions enabled on the assessment type can delete launched assessments and assessment objects.
Email Daily Digest
The Messaging action on a workflow now offers a nightly delivery frequency to queue all the email notifications a user would receive for the transition in a single email. If the same role and email template are selected for additional Messaging actions, users will receive one email with a consolidated list of all the objects that require their attention, even if they're from multiple object types. For added convenience, admins also have the option to include a link in the email to the user's homepage (My Tasks or starred reports).
Workflow State Variables
Administrators can use workflow states as relationship/reference variables in conditions or formulas. Depending on the sub-type selected, these variables will check if some or all of the objects are in the specified state or provide a count of the objects in that state.
Identify Form Conflicts & Set a Priority
When a user belongs to two or more roles that have permission to view the same object, Core will automatically display the most recently created standard form for that object, which could create a form conflict. Now, using the Impersonate feature, administrators can navigate to a particular form to check if a conflict exists. 
If a form conflict does exist, a number can be entered into the new Priority field when editing the form, so that the form with the higher assigned priority is displayed to the user.
Heat Map Display
Two new options in the heat map settings allow administrators to show or hide decimals for assessment objects as well as the field or formula names selected for the X and Y axes.

UI Improvements
The user interface for objects displayed in search results, the assessment scoping screen, and the advanced relationship/reference palette have been streamlined with a more intuitive design. This includes hiding references to assessments if no assessment data exist, automatically displaying existing objects that can be added to a relationship or reference through the palette, and displaying a message when a search yields no results.
