We are still pre-1.0, but we need to give users a way to know when breaking changes are made and upgrade accordingly.

As discussed in the TUF community meeting, we intend to version pre-1.0 releases as v0.x.y, where x is incremented for breaking changes.

We will build release notes from a changelog file, updated in each PR as necessary. Changes will be tagged by sub-system, like [client], [cli], or similar.

A PR review checklist may help with the process.
