Azure Sphere Preview—Update 19.09 is now available for evaluation

Published date: 25 September, 2019

The Azure Sphere Preview 19.09 feature release is now available via the retail evaluation feed. The retail evaluation is meant for backwards compatibility testing. Use the retail evaluation feed to verify production-signed applications against the new release before we deploy it broadly on the retail feed. If you encounter problems, please notify us immediately through your Microsoft technical account manager (TAM) so that we can address any issues. Microsoft engineers and Azure Sphere community experts will also respond to product-related questions on our MSDN forum and development questions on Stack Overflow. The regular retail OS feed will continue to deliver version 19.07 and we plan to upgrade the retail OS feed to 19.09 sometime in early October.

To install the 19.09 update on your devices during the evaluation period, you will need to set up an OTA configuration that receives updates from the retail evaluation OS feed, if you have not already done so. For more information on how to change the configuration, see Set up a device group for OS evaluation.  

Important: We have changed the name of the time server to (instead of Your network firewall settings must enable access to this host so that your device can continue to receive over-the-air updates and new certificates.

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. For information on how to proceed in that case, see the previous version’s release notes.
