The updated OS has now been issued to Retail Eval and we expect to release the OS to retail after seven days, on 20 June.
Updated 30 May
The Azure Sphere 23.05 release, originally expected on May 24, is delayed. A compatibility risk concerning library version dependencies was found by quality assurance tests, and we will issue a new OS to fix this. We expect the new OS to go live in retail-eval on 5 June and we are planning to use a shorter retail-eval period of seven days.
The retail evaluation period provides a period for backwards compatibility testing. During this time, customers can verify that applications and devices operate properly with a new OS before it’s deployed broadly via the Retail feed. The Retail feed will continue to deliver OS version 23.02 until we publish the 23.05 update.
Areas of special focus for compatibility testing with the 23.05 release should include apps and functionality utilizing:
- Azure IoT Hub
- wolfSSL API calls (such as custom TLS Client or Server)
- TLS connections
- UART
