Azure Sphere OS version 21.10 is now available for evaluation in the Retail Eval feed. The retail 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's deployed broadly via the Retail feed. The Retail feed will continue to deliver OS version 21.09 until we publish 21.10.
The evaluation release of version 21.10 includes an OS update only; it does not include an updated SDK. When 21.10 is generally available later in October, an updated SDK will be included.
Compatibility testing with version 21.10
Areas of special focus for compatibility testing with 21.10 should include apps and functionality using wolfSSL.
Notes about this release
The most recent RF tools (version 21.01) are expected to remain compatible with OS version 21.10.
