Month: 2026-03 — Leonidas-from-XIV/dune. Delivered an error-diagnostics enhancement that clarifies build failures caused by directories excluded by a dirs stanza. When attempting to build a target in an excluded directory, dune now prints a clear hint indicating the exclusion and the location of the dirs stanza, guiding developers to the root cause and reducing debugging time. The change is isolated to the error path and does not affect normal build behavior, preserving performance.

Month 2024-11: Focused on improving build reliability by expanding regression coverage for Dune's cache behavior. Delivered a blackbox test that verifies empty directories are correctly restored from the Dune cache after a build, addressing cache restoration edge cases and preventing regressions. The change aligns with ongoing efforts to stabilize the developer experience around build caching and reproducibility.
