What's changed

Changes to Now Assist usage measurement

Starting with Yokohama Patch 5, Now Assist usage measurement is transitioning from a 365-day look-back model to a 365-day burn-down model, with usage resetting at the contract anniversary date. For more information, refer to KB KB2704710: Now Assist Usage - Overview & New Measurement Logic.

Some Now Assist skills, agents, and agentic workflows are turned on by default

The skills are automatically available to appropriate role users for the application, such as ITIL roles on incident forms or change forms. This change simply activates the skill and does not touch the roles that may be needed to use the skill. The new default behavior works as follows:

New customers: When you install a Now Assist product, designated skills and agentic workflows are turned on automatically.
Existing customers who are upgrading (starting with Yokohama Patch 11): Any previously unconfigured skill, agent, or agentic workflow is turned on automatically (the AI asset was never configured and turned on, then turned off again). Previously configured skills and agentic workflows that were turned on, then off, remain inactive.

Configure ACLs for AI agents and agentic workflows

Configure the access control lists for who can discover and trigger AI agents and agentic workflows in their guided setups in AI Agent Studio. You can determine whether an AI agent or agentic workflow behaves as a dynamic user or as an AI user. You can also specify if an AI agent or agentic workflow can be available to all authenticated users or publicly available.
