Nobody touched the code. What happened is that a comparator matched <code>2.0.0-rc.1</code> against <code>&gt;=1.0.0 &lt;2.0.0</code>, a resolver decided the release candidate was good enough, and the deploy bot rolled it out. Version comparison is one of those problems that looks like string manipulation and behaves like a parser spec: six mainstream ecosystems each implement it slightly differently, and the differences are exactly where production breaks.</p>
