Azure Sphere OS version 22.02 is now available for evaluation in the Retail Eval feed. The evaluation period provides 2 weeks 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 21.10 until we publish 22.02.
The evaluation release of version 22.02 includes an OS update only; it does not include an updated SDK. When 22.02 is generally available later in February, an updated SDK will be included.
Compatibility testing with version 22.02
Areas of special focus for compatibility testing with 22.02 should include apps and functionality using:
- Timestamps or structs that contain time
- Manually configured DNS entries
- Wired Ethernet connections
Notes about this release
- The most recent RF tools (version 21.01) are expected to remain compatible with OS version 22.02.
