Azure Sphere typically issues one or two quality releases in between quarterly feature releases. Feature releases support new functionality and include both the Azure Sphere OS and the SDK. Quality releases include bug fixes and performance enhancements, and usually include only the Azure Sphere OS.
Quality release 21.11 will not be issued
No relevant bug fixes or performance enhancements have been identified during the 21.11 development period, and as a result Azure Sphere will not issue a 21.11 release. The Retail feed will continue to deliver version 21.10 until the next release. We will continue to publish updates to documentation, samples, and gallery projects.
