   * `broadcast_zpreserving` has been deprecated ([#19533], [#19720]).
 
+  * `@test_approx_eq a b` has been deprecated in favor of `@test a ≈ b` (or,
+    equivalently, `@test ≈(a, b)` or `@test isapprox(a, b)`).
+    `@test_approx_eq_eps` has been deprecated in favor of new `@test` syntax:
+    `@test` now supports the syntax `@test f(args...) key=val ...` for
+    `@test f(args..., key=val...)`. This syntax allows, for example, writing
+    `@test a ≈ b atol=c` in place of `@test ≈(a, b, atol=c)` (and hence
+    `@test_approx_eq_eps a b c`) ([#19901]).
+
   * `convert` methods from `Diagonal` and `Bidiagonal` to subtypes of
     `AbstractTriangular` have been deprecated ([#17723]).
