Update 19.03 for Azure Sphere public preview now available for evaluation

Published date: March 15, 2019

We now support both a Retail Evaluation feed and a Retail feed for the Azure Sphere OS. The 19.03 release will initially be available via the Retail Evaluation feed. The regular Retail OS feed will continue to deliver version 19.02; we plan to upgrade it to 19.03 in two weeks.

To install the 19.03 update on your devices before we release it on the Retail OS feed, you'll need to change its OTA update configuration to receive updates from the Retail Evaluation OS feed. For more information on how to change the configuration, see Set up a device group for OS evaluation.

As a reminder, if your device is still running a release older than 18.11, it will be unable to authenticate to an Azure IoT Hub via DPS or receive OTA updates. See the release notes for how to proceed in that case.

As always, we thank our preview customers for your comments and suggestions. Microsoft engineers and Azure Sphere community experts will respond to product-related questions on our MSDN forum and development questions on Stack Overflow. We also welcome product feedback and new feature requests.
