Worked on the oxcaml/oxcaml repository to deliver a forward-compatibility feature focused on supporting OCaml 5.2.0 toolchains. Addressed version compatibility by updating the OCaml magic number from 552 to 553 and adjusting the build configuration to match the new version requirements. This change, implemented using M4 and build system configuration skills, reduced build failures with newer toolchains and enabled users to adopt features from OCaml 5.2.0. The update also contributed to more stable continuous integration and deployment pipelines, ensuring downstream compatibility and smoother development workflows for teams relying on up-to-date OCaml environments in their projects.
