+Subject: [PATCH] Do not split query strings on `;` anymore.
+
+Using `;` as a separator instead of `&` was allowed a long time ago,
+but is now obsolete and actually invalid according to the 2014 W3C
+recommendations. Even if this change is technically backwards-incompatible,
+no real-world application should depend on broken behavior. If you REALLY
+need this functionality, monkey-patch the _parse_qsl() function.
