Drop compat code for atan from #574

README.md

@@ -78,8 +78,6 @@ Currently, the `@compat` macro supports the following syntaxes:
 * `Compat.split` and `Compat.rsplit` accept `keepempty` keyword argument
   if `splitter` is given as second argument ([#26634])
 
-* `atan2` is now a 2-argument method of `atan` ([#27253]).
-
 * `realmin` and `realmax` are now `floatmin` and `floatmax` ([#28302])
 
 * `squeeze` is now `dropdims` ([#28303], [#26660]).
