-#### 7/23/26
-  - Use `mp_printf()`, recently included in [MP-Test](4), in place of
-    `fprintf()` everywhere to allow redirecting of console output.
+#### 8/4/26
+  - Add support for redirecting console output via `mp.logger` by replacing
+    `fprintf()` and `warning()` everywhere with `mp_printf()` and
+    `mp_warning()`, respectively. Requires [MP-Test](4) 8.2 or later.
