Thread:Help talk:Special properties/Backward compability! Backward compability! Backward compability!!!

As of 1.9.1, special property Subproperty of again requires the prefix. Long ago, we had to write. Then it changed to . Now  again points at Superproperty in the main namespace rather than Property:Subproperty, so we have to rewrite all property pages, thank you very much.

Is it a bug or a feature?
