  1. Is there any plan to release a new version of Office Online Server just like Microsoft did with the Workflow Manager? Or we will need to use the same Office Online Farm with SharePoint SE?


    1. Hi Ionut,
      Office Online server is already an evergreen product since year 2016.
      Similar to SharePoint Server Subscription Edition it will be updated every month but no new versions are planned to be released.
