The 21.06 Azure Sphere OS quality update is now available in the Retail feed. This release includes bug fixes in the Azure Sphere OS; it does not include an updated SDK. If your devices are connected to the internet, they will receive the updated OS from the cloud.
21.06 includes updates and enhancements in the following areas.
- Open-source code can now be built in a manner that better reflects its use in the Azure Sphere OS. Previously wpa_supplicant did not properly link to wolfSSL.
- When writing to flash devices over SPI from high level apps, corruption was possible under certain conditions due to using byte aligned writes instead of word aligned writes. This issue is resolved, and writes are now optimized for cases smaller and larger than 1 word.
