Worked on the mason-registry repository to upgrade the Haskell Language Server to version 2.13.0, focusing on maintaining compatibility with existing configurations while enabling access to new server features. The approach emphasized minimal disruption by targeting only the necessary changes, ensuring that users could adopt the update without extensive migration. Leveraged expertise in Haskell and package management to validate integration with current tooling and lay the groundwork for future enhancements. The work addressed the need for ongoing ecosystem updates, improving the developer experience and supporting continued project stability. No bug fixes were required during this period, reflecting a focused feature delivery.
