The Azure Sphere update 20.04 is now available for evaluation via the retail evaluation feed. The retail evaluation period provides 14 days for backwards compatibility testing. During this time, please verify that your applications and devices operate properly with this release before it's deployed broadly via the retail feed. The retail feed will continue to deliver OS version 20.03 until we publish the 20.04 update in 14 days. The evaluation release includes an OS update only—it doesn’t include an updated SDK.
For more information, please read our post on the Internet of Things on Microsoft Tech Community.
For more information on Azure Sphere OS feeds and setting up an evaluation device group, see Azure Sphere OS feeds.
If you encounter problems, please notify us immediately through your Microsoft technical account manager (TAM) so that we can address any issues. Microsoft engineers and Azure Sphere community experts will also respond to product-related questions on our MSDN forum and development questions on Stack Overflow.
