Current Behavior

a diff between a non prerelease version like 5.5.0 and a prerelease version on the same patch now creates a major diff while it previously was prerelease

see https://github.com/npm/node-semver/pull/566/files

Expected Behavior

It should be either prerelease or mention the breaking change it the changelog and why you think it should be that way.

Steps To Reproduce

import semverDiff from 'semver/functions/diff'; // is major console.log(semverDiff('1.0.0-alpha.1', '1.0.0'));

Environment
