15 Commits • 5 Features

May 1, 2026

May 2026 saw multiple high-impact feature deliveries and reliability improvements across flox/flox and ECC. Key work includes adapting tests to the Catalog API's new system ordering and latest hello package version, refactoring publish deduplication with a dedicated rev extractor, and standardizing CLI output for a more consistent UX. Infrastructure enhancements improved type safety and URL handling, and we enabled the flox-forge-agent bot to streamline Claude code reviews. A new cross-platform development environments skill was added to ECC to enable reproducible workflows. Overall, these efforts reduced test fragility, improved developer experience, and strengthened the foundation for reliable publishing and tooling.
