The "Automated releases" entry was written under v0.3.0, but that commit landed after the v0.3.0 tag -- the CHANGELOG was claiming the release contained something it did not. Moved to its own version rather than left as a quiet inaccuracy. Bumps VERSION to 0.3.1 across all four scripts, which the new consistency check now enforces.
