 ### BuildKit support
 
-The enhanced functionality and performance provided by the [Docker BuildKit](https://docs.docker.com/build/buildkit/) is now fully available to be leveraged in your Pulumi programs. BuildKit comes with functionality to improve your builds’ performance and the reusability of your Dockerfiles. Cross-platform builds are now supported, enabling image building for a target container runtime that is different from the build environment. BuildKit is now the default builder version mode. The V1 builder can still be accessed by specifying `Build.BuilderVersion=V1`.
