Please uncomment the line below (and provide explanation) if the changes fix
either (a) a security vulnerability, (b) a bug that caused incorrect or invalid
data to be produced, or (c) a bug that causes a crash (even when the API
contract is upheld). We use this to highlight fixes to issues that may affect
users without their knowledge. For this reason, fixing bugs that cause errors
don't count, since those are usually obvious.
