Customer Engagement Online Timeline

Dynamics 365 Customer Engagement Online is expected to receive new features twice a year in April and October updates, although the team has struggled to maintain a consistent release schedule in the past. Current and upcoming versions of the online service are shown here. The latest major version, called 9.1, became generally available in Oct. 2018.

In the Aug. 2018 Business Applications Summit, Microsoft announced that it was modifying the existing support end dates for older versions and, beginning in Feb. 2019, will support only the latest generally available version of the service. Previously, the service allowed customers to remain on a major version as long as it was no more than one version behind the most current major version, which meant Microsoft was supporting the two most current versions. The new servicing model will require customers to accept updates twice per year, resulting in more testing of customizations and recertification of systems for regulatory compliance.
