 Deprecated or removed
 ---------------------
 
+  * `ipermutedims(A::AbstractArray, p)` has been deprecated in favor of
+    `permutedims(A, invperm(p))` ([#18891]).
+
   * Linear indexing is now only supported when there is exactly one
     non-cartesian index provided. Allowing a trailing index at dimension `d` to
     linearly access the higher dimensions from array `A` (beyond `size(A, d)`)
