pack v0.28.0-rc1

This is a beta pre-release of the Cloud Native Buildpack local CLI. This platform implementation should be relatively stable and reliable, but breaking changes in the underlying specification may be implemented without notice.

Prerequisites

• A container runtime such as Docker or podman must be available to execute builds.
