@@ -74,8 +74,6 @@ Currently, the `@compat` macro supports the following syntaxes:
 
 * Single-argument `permutedims(x)` for matrices and vectors ([#24839]).
 
-* `isbits(t::Type)` is now `isbitstype(t)` ([#26850]).
-
 * `something` to get the first argument different from `nothing`, unwrapping those
   of the `Some` type ([#27258]).
