Release Notes

docker/build-push-action (docker/build-push-action)

### [`v4.2.1`](https://togithub.com/docker/build-push-action/releases/tag/v4.2.1) [Compare Source](https://togithub.com/docker/build-push-action/compare/v4.2.0...v4.2.1) > **Note** > > Buildx v0.10 enables support for a minimal [SLSA Provenance](https://slsa.dev/provenance/) attestation, which requires support for [OCI-compliant](https://togithub.com/opencontainers/image-spec) multi-platform images. This may introduce issues with registry and runtime support (e.g. [Google Cloud Run and AWS Lambda](https://togithub.com/docker/buildx/issues/1533)). You can optionally disable the default provenance attestation functionality using `provenance: false`. - warn if docker config can't be parsed by [@​crazy-max](https://togithub.com/crazy-max) in [https://github.com/docker/build-push-action/pull/957](https://togithub.com/docker/build-push-action/pull/957) **Full Changelog**: https://github.com/docker/build-push-action/compare/v4.2.0...v4.2.1
