Worked on the JetBrains/intellij-plugin-verifier repository to prepare for the 1.398 release by updating and validating the release notes and changelog. Focused on ensuring that documentation accurately reflected new features and changes, which improved clarity for customers and streamlined the release process. Used Markdown for documentation and applied version control best practices to maintain traceability of updates. The work emphasized aligning documentation with actual product changes, supporting smoother communication and future maintenance. No bugs were fixed during this period, and the primary contribution centered on enhancing release-readiness through precise, well-organized documentation and careful management of release information.
