Azure Sphere OS version 21.04 is now available for evaluation in the Retail Eval 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 is deployed broadly via the Retail feed. The Retail feed will continue to deliver OS version 21.03 until we publish 21.04 in two weeks. For more information on retail evaluation see our blog post, The most important testing you'll do: Azure Sphere Retail Evaluation.

 

This evaluation release includes an OS update only; it does not include an updated SDK.

 

Notes about this release

    • Any wolfSSL calls, as it has been upgraded to version 4.7.
    • Wi-Fi connectivity as the background scanning process had been upgraded.
  • 21.04 includes updates to mitigate against the following CEVs:
    • CVE-2021-28460
    • CVE-2021-22876
    • CVE-2021-22890
