When running `./gradlew check`, minimal bwc checks are also run against compatible versions that are not yet released.

==== BWC Testing against a specific remote/branch

Sometimes a backward compatibility change spans two versions. A common case is a new functionality
that needs a BWC bridge in an unreleased versioned of a release branch (for example, 5.x).
