Leonhard Neuhaus worked on release management for the XanaduAI/MrMustard repository, focusing on preparing the project for downstream packaging and distribution. He updated the pyproject.toml file to bump the package version to 1.0.0-dev and revised the changelog in Markdown to accurately document the new release. Leveraging skills in build management and version control, Leonhard ensured that the repository’s metadata supported reproducible builds and clear release traceability. While the scope of work was limited to a single feature over one month, the changes addressed essential aspects of packaging readiness, enabling more reliable consumption and tracking for users and downstream projects.
