Worked on the simonmichael/stackage repository to enhance build stability by addressing dependency compatibility issues. Focused on build system configuration using YAML, the developer delivered a targeted fix that constrained the inf-backprop package to a version of isomorphism-class compatible with newer library releases. This approach reduced the risk of build failures in continuous integration and future releases, supporting smoother upgrades and improved dependency hygiene. The work involved careful analysis of dependency relationships and validation of changes through documentation and commit messaging. Although no new features were added, the contribution strengthened the reliability of the build process for ongoing development.
