General availability: Azure Sphere OS version 22.01 expected on Jan 26

This post has been republished via RSS; it originally appeared at: New blog articles in Microsoft Tech Community.

Azure Sphere OS version 22.01 is now available for evaluation in the Retail Eval feed. The retail evaluation period provides 14 days for backward compatibility testing. During this time, please verify that your applications and devices operate properly with this release before it is deployed broadly to devices in the Retail feed. The Retail feed will continue to deliver OS version 21.10 until we publish 22.01 in two weeks. 


This evaluation release includes enhancements and bug fixes for the OS only; it does not include an updated SDK.


Areas of special focus for compatibility testing with 22.01 should include apps and functionality utilizing:

  • Timestamps or structs that contain time
  • WifiConfig_getNetworkDiagnostics()
  • Manually configured DNS entries
  • DMA


For more information on Azure Sphere OS feeds and setting up an evaluation device group, see Azure Sphere OS feeds and Set up devices for OS evaluation.
