General availability: Azure Sphere version 21.07 expected on July 21, 2021

Published date: July 01, 2021

Azure Sphere OS version 21.07 is now available for evaluation in the Retail Eval feed. The retail evaluation period for 21.07 provides 3 weeks 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 21.06 until we publish 21.07 in 3 weeks. For more information on retail evaluation see our blog post, The most important testing you'll do: Azure Sphere Retail Evaluation.

The evaluation release of version 21.07 includes an OS update only; it does not include an updated SDK. When 21.07 is generally available later in July, an updated SDK will be included.

Compatibility testing with version 21.07

The Linux kernel has been upgraded to version 5.10. Areas of special focus for compatibility testing with 21.07 should include apps and functionality using kernel memory allocations and OS dynamically-linked libraries.

Notes about this release

  • The most recent RF tools (version 21.01) are expected to be compatible with OS version 21.07.
  • Azure Sphere Public API can be accessed programmatically using Service Principal or MSI created in a customer AAD tenant.
