Worked on the smarty/changelog repository to deliver comprehensive migration documentation for the 10.0.0 release, focusing on the transition from HttpWebRequest to HttpClient. Emphasized asynchronous-by-default patterns in .NET, clearly outlining available blocking options and the rationale behind the migration. Utilized Markdown for changelog management and documentation, ensuring that SDK users understood the performance and scalability benefits of the new approach. The work prioritized clear communication to minimize friction for downstream developers, aligning documentation with modern .NET practices. No bug fixes were recorded during this period, as efforts centered on feature delivery and improving the overall developer experience through detailed guidance.
