Azure Sphere OS version 22.04 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 22.02 until we publish 22.04 in two weeks.
This evaluation release includes enhancements and bug fixes for the OS only; it does not include an updated SDK. We recommend using the Azure Sphere SDK version 22.02 Update 1 for compatibility testing.
Areas of special focus for compatibility testing with 22.04 should include apps and functionality utilizing:
- TLS and certificates with non-Azure hosts
- TLS 1.3 connections with any host
- Any data structure containing time_t
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.
