When are interface versions published?

Context

In order for a developer to understand when they should change an interface version, it is necessary to understand when an interface version is considered published (and intended to be immutable)

Given that many of our interfaces are currently defined within the same repository of the reference implementation, they are rarely updated in isolation.

Options

• The interface is published when the reference implementation is formally released
• The interface is published when the change is merged to the master branch of the reference implementation
