Update 1 of the Azure Sphere OS version 21.02 is now available for evaluation in the Retail Eval feed. This release fixes a security vulnerability discovered since the last release. This update will not restart the 21.02 evaluation period because the change will not impact any customer scenarios. The Retail feed will continue to deliver OS version 21.01 until we publish 21.02 later this week.
The evaluation release includes only an OS update; it does not include an updated SDK.
