 Runtime developers can build runtime implementations that run OCI-compliant bundles and container configuration, containing low-level OS and host-specific details, on a particular platform.
 
-## Releases
-
-There is a loose [Road Map](./ROADMAP.md).
-During the `0.x` series of OCI releases we make no backwards compatibility guarantees and intend to break the schema during this series.

 ## Contributing
 
 Development happens on GitHub for the spec.
