Sunny Yuan updated the Kubernetes compatibility matrix in the MicrosoftDocs/azure-stack-docs repository, ensuring documentation accurately reflected supported versions and OS image mappings. By removing deprecated Kubernetes version 1.32.9 and adding 1.33.6 and 1.33.7, Sunny aligned the documentation with the 4.9 Version Bundle, reducing ambiguity for operators and support teams. The work involved careful manual editing of Markdown files and close attention to DevOps best practices, particularly around Kubernetes versioning. Although the scope was focused, the update improved deployment guidance for users and maintained consistency with release changes, demonstrating a methodical approach to technical writing and documentation maintenance.
