Drop compat code for parentmodule from #461

README.md

@@ -143,9 +143,6 @@ Currently, the `@compat` macro supports the following syntaxes:
 
 * `reprmime(mime, x)` is now `repr(mime, x)` ([#25990]) and `mimewritable` is now `showable` ([#26089]).
 
-* `module_parent`, `Base.function_module`, and `Base.datatype_module` are now methods of
