Azure Sphere 20.04 Update 1 is now available for compatibility testing

Azure Sphere 20.04 Update 1 is now available via the Retail Eval feed. This update fixes a bug that could cause a failure when the device tries to bring up the Ethernet interface after a reboot. The bug represented a regression from the 20.03 release and was reported by customers during the initial Retail Evaluation period. We are grateful to our customers for immediately reporting the problem, so that we could fix it quickly.

Because of this change to the OS, the retail evaluation period will start over. 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 final 20.04 release in two weeks. The 20.04 evaluation release includes an OS update only; it does not 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.
