Microsoft Dynamics 365 - Service Update 159 Release Notes

Service Update 159 for Microsoft Dynamics 365 9.1.0 is now available. This article describes the hotfixes and updates that are included in Service Update 159.


Note: Service Update naming convention has been revised to clarify the link between the version number and Service Update number. For example, Service Update 150 will now correspond to version number 150xx. Occasionally a Service Update will be canceled and all associated fixes will be rolled into a subsequent Service Update. For this reason, Service Update numbers may not always increase incrementally.
