The roadmap items are broken into the following broad categories:

  - container runtimes
  - hypervisor base support
  - build system / workflow
  - container stacks / management
  - container images / applications / artifacts
  - container base / support components (tools, plugins, etc)

Legend: [x] = done, [ ] = TODO, [~] = partial/in-progress
