Update 19.05 for Azure Sphere public preview now available for evaluation

Published date: May 16, 2019

The Azure Sphere public preview 19.05 feature release is available today via the Retail Evaluation feed. The regular Retail OS feed will continue to deliver version 19.04; we plan to upgrade it to 19.05 in two weeks. 

To install the 19.05 update on your devices during the evaluation period, you'll need to set up an OTA configuration that receives updates from the Retail Evaluation OS feed, if you did not already do so for the 19.04 release. 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
