During March 2026, Nineclue focused on maintaining and upgrading the test infrastructure for the com-lihaoyi/mill repository. They migrated the project’s test framework from the archived weaver-test to the actively maintained typelevel/weaver-test, updating dependency coordinates and tooling to align with the modern Scala testing ecosystem. This work, implemented in Scala and involving dependency management and testing frameworks, addressed the risk of deprecated tooling and improved CI stability. Although the migration did not introduce user-facing features, it enhanced long-term maintainability and testing reliability, ensuring the project remains compatible with current technologies and supporting future upgrades with minimal disruption.
