     This change makes `@schedule` redundant with `@async`, so `@schedule` has been
     deprecated ([#27164]).
 
+ * `norm(A::AbstractMatrix, p=2)` computes no longer the operator/matrix norm but the `norm` of `A`
+   as for other iterables, i.e. as if it were a vector. Especially, `norm(A::AbstractMatrix)` is the
+   Frobenius norm. To compute the operator/matrix norm, use the new function `opnorm` ([#27401]).
+
+  * `dot(u, v)` now acts recursively. Instead of `sum(u[i]' * v[i] for i in ...)`, it computes
+    `sum(dot(u[i], v[i]) for i in ...)`, similarly to `vecdot` before ([#27401]).
