## Key Features and Changes

* **New 2024 Schedule Engine (Xanadu):** Introduces an enhanced scheduling engine that improves managing schedules and shifts by resolving gaps caused by member changes, holidays, or extra time. It ensures continuity by verifying the last on-call member and offers improved performance when adding, removing, or moving members. This upgrade is automatic.
* **Email Link Redirection (Yokohama):** Enables control over where links in major on-call schedule and shift email notifications open. Instead of defaulting to the classic UI16 interface, links can now open in the Service Operations Workspace (SOW) if:
  * The relevant redirect properties are enabled (sowemailnotificationredirect and sowemailnotificationredirect.oncall)
  * The user has the snsowuser role
  * The ITSM Notifications Redirection plugin is installed and activated

## Activation Information

On-Call Scheduling is activated through the ServiceNow AI Platform On-Call Scheduling plugin (com.snc.oncallrotation) in both Xanadu and Yokohama releases. Activating this plugin also activates supporting third-party libraries such as FullCalendar and DHTMLX scheduler. For zBoot customers, this plugin is enabled by default.

## Additional Notes

* No features or functionalities were removed or deprecated between Xanadu and Yokohama releases.
* There are no additional specific browser, accessibility, or localization requirements introduced in these releases.
* Upgrade preparation includes reviewing and completing pre- and post-upgrade tasks to ensure smooth transition.

## Practical Benefits for ServiceNow Customers

* Improved efficiency and reliability in managing on-call shifts and schedules with the 2024 schedule engine.
* Greater flexibility in accessing on-call schedule details via email notifications by choosing UI16 or Service Operations Workspace, enhancing user experience.
* Simplified activation and upgrade process with clear guidance and automatic plugin activation for eligible customers.
