General availability: Azure Sphere OS version 23.05 expected on May 24

The Azure Sphere update 23.05 is now available for evaluation via the Retail Eval feed. The retail evaluation period provides 14 days for backwards compatibility testing. During this time, please verify that your applications and devices operate properly with this release before it is deployed broadly to devices in the Retail feed. The Retail feed will continue to deliver OS version 23.02 until we publish the 23.05 update in two weeks.

This evaluation release includes enhancements and bug fixes for the OS only; it does not include an updated SDK.  

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
