Key Updates and Compatibility Recommendations

Microsoft notes that the operation of cURL-multi has undergone some changes, particularly regarding recursive calls. Despite efforts to maintain backward compatibility for applications compiled against previous versions, the company advises users to thoroughly test their applications to ensure their proper function under the new OS version. Microsoft emphasizes the importance of focusing on cURL-multi's behavior during the evaluation phase to avoid potential issues in production environments.

Background and Future Implications

Released to the public in February 2020, OS represents Microsoft's first foray into a Linux kernel-based operating system, and its second venture into Unix-like systems following the now-defunct Xenix. The development and release of Azure Sphere OS underscore Microsoft's ongoing commitment to security and broadening its technology ecosystem to include Linux-based solutions. This latest update not only addresses key security and functionality concerns but also reaffirms Microsoft's dedication to backward compatibility and long-term support. As Azure Sphere continues to evolve, it plays a crucial role in Microsoft's strategy to offer secure and versatile solutions for IoT devices and beyond.

For those interested in exploring the Azure Sphere OS feeds or setting up an evaluation device group, Microsoft provides dedicated resources to facilitate these processes.
