**[Yokohama Patch 11](https://servicenow-prod.fluidtopics.net/o~Ty6nl6ETxZAE_DIVoJJw "The Yokohama Patch 11 release contains important problem fixes.")**
[Changes to Now Assist usage measurement](https://www.servicenow.com/docs/access?context=monitoring-now-assist-usage&version=yokohama&pubname=yokohama-platform-administration&ft:locale=en-US)

For more information, refer to [KB KB2704710: Now Assist Usage - Overview \& New Measurement Logic](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2704710).

:   The new default behavior works as follows:

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