Worked on packaging and release engineering for the coq/opam repository, focusing on MathComp library updates. Delivered new opam definitions, dependency specifications, metadata, and build instructions for MathComp v2.4.0 core libraries and v2.2.0 finmap, using OCaml and Coq. Emphasized reproducible builds and streamlined downstream integration by providing release-ready tarballs and explicit dependency management. All changes were tracked through documented commits, ensuring traceability and maintainability. The work centered on package management and mathematical libraries, with no major bug fixes during the period. This approach improved release clarity and facilitated smoother deployments for users relying on the coq/opam ecosystem.
