The Azure Sphere OS public preview 19.11 quality release is now available via the Retail feed. If your devices are currently running the 19.10 OS or an earlier OS release and are connected to the internet, they should receive the OS update from the cloud. However, if you have an older Seeed MT3620 Development Kit, you might need to update manually, as described in Update the OS on an early dev kit.
This quality release fixes an error in I2C reads that was reported on MSDN and an error in which SPI reads or writes may cause the system to crash. In addition, it includes changes to mitigate against CVE-2019-18840.
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.
