The purpose of the rules is to give you a framework to operate in that is easily understood in the vast majority of situations, not to comprehensively define every aspect. You don&amp;#x27;t get any rewards for following the rules, after all. When things get weird, you just ask the DM, they make a ruling, and then you keep the game moving forward.&lt;p&gt;There&amp;#x27;s always going to be corner cases.

Like if a function called with certain parameters causes an unexpected crash, and a user decided to use that to quit the application, you can&amp;#x27;t reasonably be expected to maintain that behaviour.&lt;p&gt;If the bug was that a well documented function actually behaved differently than was expected but still consistently (like a string function that was supposed to return a number of characters but really returned a number of bytes) then yeah, that&amp;#x27;s a breaking change.&lt;p&gt;In practice the line can be fuzzy of course, but I find that it&amp;#x27;s not usually to hard to decide what constitutes a breaking change and what doesn&amp;#x27;t.</text><parent_chain><item><author>dariusj18</author><text>Something I&amp;#x27;ve never quite understood about semantic versioning.
