Applies to Dynamics 365 (online) version 9.0.x

Microsoft is modernizing version numbering to better reflect which changes are delivered. This should contribute to the transparency of product updates.

With the October update to Microsoft Dynamics 365 for Customer Engagement, one of the changes made is to increment the version number to 9.1 for our online service.

The update from 9.0.x to 9.1.x will happen automatically; you don’t need to schedule anything.

The new version number – Microsoft Dynamics 365 for Customer Engagement apps, Version 9.1, Online – will begin rolling out in-product starting October 1, 2018.
