When planning your environments it is useful to know the current releases of D365FO that are supported.
Microsoft publish this information. The schedule for specific releases of D365FO is available at this link:
Note: As of the 10.0.38 update the naming convention changed to be more date specific.
e.g. the 10.0.45 update, which was released in early June 2026 is officially named CY26Q3 (meaning the 3rd quarter update for the Calendar Year 2026 release schedule).
D365FO Updates now release 4 times a year, and the odd numbered updates (the "Q2" and "Q4" updates for a given CYXX block, will be "major" updates, meaning they contain changes as well as fixes, whereas the even numbered updates (the "Q1" and "Q3" updates contain mostly bug fixes.
The above table normally lists the date for the next 4 updates.
Note: We at Farsight do not do any compatibility assessment or testing of any D365FO updates prior to the given update becoming Generally Available. And once a given update is Generally Available we will do any testing we believe is required for compatibility purposes only. And publish the results elsewhere in the Knowledge Base.
If you are planning on deploying a D365FO update prior to General Availability with Demand Forecasting you are strongly advised to ensure you do full compatibility testing with that preview D365FO update in a UAT system and repeat as needed using the Generally Available update once its released. Prior to deployment of the update to Production.
