## 0.9.0

{{< release-date date="2022-08-17" >}}

### New

- Support for a new [`remote` driver](/manuals/build/builders/drivers/remote.md) that you can use
  to connect to any already running BuildKit instance.
  [docker/buildx#1078](https://github.com/docker/buildx/issues/1078),
  [docker/buildx#1093](https://github.com/docker/buildx/issues/1093),
  [docker/buildx#1094](https://github.com/docker/buildx/issues/1094),
  [docker/buildx#1103](https://github.com/docker/buildx/issues/1103),
  [docker/buildx#1134](https://github.com/docker/buildx/issues/1134),
  [docker/buildx#1204](https://github.com/docker/buildx/issues/1204)
- You can now load Dockerfile from standard input even when the build context is
  coming from external Git or HTTP URL. [docker/buildx#994](https://github.com/docker/buildx/issues/994)
- Build commands now support new the build context type `oci-layout://` for loading
  [build context from local OCI layout directories](/reference/cli/docker/buildx/build.md#source-oci-layout).
  Note that this feature depends on an unreleased BuildKit feature and builder
  instance from `moby/buildkit:master` needs to be used until BuildKit v0.11 is
  released. [docker/buildx#1173](https://github.com/docker/buildx/issues/1173)
- You can now use the new `--print` flag to run helper functions supported by the
  BuildKit frontend performing the build and print their results. You can use
  this feature in Dockerfile to show the build arguments and secrets that the
  current build supports with `--print=outline` and list all available
  Dockerfile stages with `--print=targets`. This feature is experimental for
  gathering early feedback and requires enabling `BUILDX_EXPERIMENTAL=1`
  environment variable. We plan to update/extend this feature in the future
