PROFILE
Matthieu Sozeau
Matthieu Sozeau contributed to the coq/opam repository by engineering robust packaging and release workflows supporting the Rocq 9.0 transition and the renaming of Coq to The Rocq Prover. He upgraded MetaCoq and MetaRocq components, introduced new package definitions, and aligned dependencies across rocq-core, rocq-stdlib, and related modules using OCaml and opam. His work included refining build systems, improving dependency management, and ensuring compatibility with Coq’s dune extension. By addressing release integrity issues and cleaning up obsolete packages, Matthieu enhanced build reproducibility and migration clarity, demonstrating depth in release engineering, repository maintenance, and OCaml ecosystem tooling.

Apr 1, 2025April 2025 monthly summary for coq/opam focusing on packaging, release integrity, and development tooling. Highlights include cleanup of obsolete package definitions, staging the official release of metacoq 1.3.4+9.0, addition of MetaRocq development packages, and Rocq-verified-extraction packaging updates with improved URL handling, install targets, and OCaml constraints. A critical bug fix corrected release hashes caused by macOS tar usage across multiple MetaCoq packages.

Mar 1, 2025March 2025 was focused on packaging and release engineering for the coq/opam ecosystem to support the Coq renaming transition and the Rocq 9.0 release. Delivered user-facing transition messaging in opam to announce the renaming of Coq to The Rocq Prover with a porting details link, and completed MetaRocq 1.4 release packaging with dependency alignment across Rocq components. These efforts improve migration clarity, build reproducibility, and cross-package maintainability.

Jan 1, 2025January 2025: Completed critical Rocq 9.0 integration work for coq/opam and hardened packaging to support downstream users upgrading to Rocq 9.0. Key achievements include upgrading MetaCoq to version 1.3.4 for Rocq 9.0 and introducing new package definitions for common, erasure, pcuic, quotation, safechecker, and template modules to align with the Rocq 9.0 release. Implemented Rocq-equations packaging and compatibility with coq-equations (version 1.3.1+9.0), and added a dedicated rocq-equations.dev package to streamline development workflows. Updated development packaging to ensure compatibility with Coq's dune language extension and to improve opam dependency resolution. These changes enhance upgrade reliability, reduce downstream integration friction, and demonstrate strong packaging, dependency management, and Coq ecosystem skills.
