Full changelog

v0.21.6 - 2026-06-10

Added

  • Add registryService options to Container.from and Container.publish, allowing containers to pull from and publish to a registry provided by a Dagger Service. This supports local ephemeral registries without starting unrelated services attached to the container. by @grouville in https://github.com/dagger/dagger/pull/13305

Fixed

  • Fix image pulls from single-platform image tags so they can resolve correctly even when the image config reports a different platform than the requested platform. by @sipsma in https://github.com/dagger/dagger/pull/13409
  • Fix an intermittent module introspection/codegen cache error that could report add explicit dependency: dep result <id> missing from cache after implementation-scoped module results were reused across sessions. by @sipsma in https://github.com/dagger/dagger/pull/13412
  • Fix filtered host directory imports when excluded files disappear during sync, preventing layer copy errors for paths that should have been ignored by include/exclude filters. by @sipsma in https://github.com/dagger/dagger/pull/13414
  • Fix Dang v2 modules with private Map fields so map values are restored correctly between calls instead of failing with expected module type, got dang.MapType. by @vito in https://github.com/dagger/dagger/pull/13421
  • Fix .env user defaults for module constructors so passing one constructor argument explicitly no longer drops defaults for the other arguments. by @marcosnils in https://github.com/dagger/dagger/pull/13424
  • Fix a rare cache race that could return released directory snapshots and cause invalid immutable ref errors. by @sipsma in https://github.com/dagger/dagger/pull/13429
