Worked on enhancing the release documentation for Jmix Studio 3.0.1 within the jmix-framework/jmix-docs repository, focusing on publishing comprehensive Release Notes and a detailed changelog. Leveraged AsciiDoc for structured documentation and integrated YouTrack to link resolved issues directly in the changelog, providing users with immediate insight into recent fixes and improvements. Utilized Git-based workflows to ensure all updates were traceable and auditable, supporting best practices in release documentation management. This work streamlined the onboarding process for the new release, reduced potential support inquiries, and established a clear, maintainable process for future documentation updates and changelog management.
