[docker/buildx#1559](https://github.com/docker/buildx/issues/1559) ## 0.10.0 {{< release-date date="2023-01-10" >}} {{< include "buildx-v0.10-disclaimer.md" >}} ### New - The `buildx build` command supports new `--attest` flag, along with shorthands `--sbom` and `--provenance`, for adding attestations for your current build. [docker/buildx#1412](https://github.com/docker/buildx/issues/1412) [docker/buildx#1475](https://github.com/docker/buildx/issues/1475) - `--attest type=sbom` or `--sbom=true` adds [SBOM attestations](attestations/sbom.md). - `--attest type=provenance` or `--provenance=true` adds [SLSA provenance attestation](attestations/slsa-provenance.md). - When creating OCI images, a minimal provenance attestation is included with the image by default. - When building with BuildKit that supports provenance attestations Buildx will automatically share the version control information of your build context, so it can be shown in provenance for later debugging. Previously this only happened when building from a Git URL directly. To opt-out of this behavior you can set `BUILDX_GIT_INFO=0`. Optionally you can also automatically define labels with VCS info by setting `BUILDX_GIT_LABELS=1`.
