What is a Compatibility Family?

A compatibility family, (aka a compatibility island), specifies a set of strategies for discovering and using the services of participating devices. Full system compatibility is maintained only within compatibility families.

To have access to the full range of functionality of a system, all components in the system should have hardware and software that is on the same compatibility island.

Full functionality is not guaranteed if devices are on different islands. As a consequence, when introducing additional equipment into an existing system, all the components should be of the same island. Typically, this would be the latest firmware release for all products.

The LinnGui application supports control of products only within the compatibility family.

Beyond these guarantees, we seek to further maintain backward compatibility, but sometimes this is not reasonably possible.
