Apr 1, 2026April 2026 monthly summary for cybozu/neco-containers focused on build determinism and registry compatibility. Implemented a reproducible Docker build workflow by pinning Dockerfiles to exact commit hashes for gitleaks, registry, and spegel, and upgraded the registry to 3.1.0 to align with the latest tooling. This reduces build non-determinism, lowers CI flakiness, and improves interoperability with upstream registry versions. No major bugs were reported or fixed this month; the primary value came from stability and reproducibility gains enabling faster releases and safer rollbacks. Key commits include 9670c42ae5fd000c0b528deb492048594a227d3c and c15a351d17071e41e81713e40758b1d4d314f85a.
