V0.20.1

v0.20.1 - 2026-03-05

🔥 Breaking Changes

• Improved git remote fetch performance by defaulting to --no-tags while preserving SHA fallback compatibility. This includes a behavior change: GitRef.tree() now excludes local .git tag refs by default (includeTags=false). Callers that need checkout-visible tags must opt in with GitRef.tree(includeTags: true) by @grouville in https://github.com/dagger/dagger/pull/11909

Added

• Added container.WithDockerHealthcheck to support publishing images with a dockerhub healthcheck by @alexcb in https://github.com/dagger/dagger/pull/11911
• drivers: add TLS driver for engine clients by @matipan in https://github.com/dagger/dagger/pull/11916

Changed

• Service containers will now use docker HEALTHCHECK commands to determine when a service is ready. If no DockerHealthcheck is defined, then it will fallback to checking the ports defined with WithExposedPort() by @alexcb in https://github.com/dagger/dagger/pull/11951
