Microsoft Dynamics 365 Business Central 2021 release wave 1 (version 18) will be available in April 2021 containing plenty of in-app improvements for better performance, usability, printing and more. However, a number of things that were marked as obsolete in Business Central 2019 release wave 2 (version 15) are removed in this version.

What does it mean for the AppSource apps and Per Tenant Extensions on Business Central Online? If solutions are not adjusted accordingly, their customers will be prevented from upgrading to the upcoming release of Dynamics 365 Business Central.

Why is it important to stay compatible?

As per Freddy Kristiansen’s message, Microsoft now validates all apps against major releases. If the app was not compatible by March 1, 2021, Microsoft did not fail it but instead got in touch to request submission of a compatible version or of a new version for the next major release. But from March 1, 2021, apps that are not compatible with Business Central 2021 release wave 1 will fail Microsoft validation.

In addition, from March 1 the customers that are running AppSource apps or Per Tenant Extensions that are not ready for Business Central 2021 release wave 1 will get Microsoft notification, as announced in the Microsoft mandatory update policy.

What can you do to make sure your apps are ready for Business Central 2021 release wave 1?

You can check whether your app or any of your dependencies are listed as not ready for Business Central 2021 release wave 1 by using this Microsoft-prepared URL:<yourappid>

In this URL, <yourappid> is the ID of your app to check. If you get a response such as ‘blob not found’ or ‘we did not find any problems’, your app is considered compatible, otherwise your app is not ready for the new release and there’s a short timeframe to fix the issues. This check ensures that your app compiles and can be installed but it does not test logic mistakes and cannot be relied on to find all the issues. For the full check-up, 1ClickFactory recommends using the automated testing and to test apps before each new release. 

If your app is not ready for 2021 release wave 1, you should fix the issues, test your app against Business Central 2021 release wave 1 and submit a new app for the AppSource validation process before the new release goes live on April 1.

However, there are even more functionalities with Obsolete Pending state indicating that will be replaced in the near future.  It becomes important not to postpone the adjustment to the last minute, when functionalities become removed. This is what 1ClickFactory takes care of with the Extension Maintenance service.
