Claudio Bernasconi updated the documentation for the reqnroll/Reqnroll repository to declare .NET 9.0 as a supported platform, clarifying compatibility with the latest .NET versions. Focusing exclusively on Markdown-based documentation, Claudio improved the README to enhance transparency around platform support, aiming to reduce onboarding friction and minimize potential support questions. No code changes were introduced, as the update centered on communication rather than implementation. The work demonstrated a targeted approach to developer experience, leveraging documentation skills to address support and compatibility concerns. The depth of the contribution was limited to documentation, with no direct impact on the codebase or feature set.
