March 2025 monthly summary for Jij-Inc/ommx: Migration to Python ABI3, experimental Python 3.13 compatibility, and CI/dependency upgrades. Focused on aligning with newer Python versions, streamlining cross-environment build/test, and improving maintainability and forward compatibility.

February 2025 monthly summary for Jij-Inc/ommx focusing on delivering business value and technical achievements. Highlights include feature delivery for solver capabilities (SOS1 constraint support) and performance/quality improvements via CodSpeed benchmarking for the Rust SDK evaluate module, along with CI automation and dependency updates to enable sustained performance visibility.

January 2025 monthly summary for commercialhaskell/lts-haskell: Focused on restoring critical packaging functionality to maintain build stability in LTS 23. Re-enabled ghc-typelits-presburger and its transitive dependents by tightening build constraints to exact version ranges, ensuring compatibility and preventing breakages in downstream packages.

December 2024 – Jij-Inc/ommx: Delivered solver optimization and SDK improvements with clear business value. Implemented ConstraintHints to guide the solver and introduced a OneHot constraint type, including proto schema and code generation for Python and Rust. Enhanced the Python SDK with typing support (py.typed) and module exports (__all__) to improve type checking. Packaging and dev tooling received dependency bumps (pyo3-stub-gen, Windows support) to improve developer experience. These changes collectively reduce solve times on representative workloads, improve safety and usability, and accelerate integration into downstream workflows.
