+- 1 minor enhancement:
+
+  - Robb Shecter changed the default log level for duplicate type variant from
+    `warn` to `debug` in [#170][]. This works because `MIME::Types.logger` is
+    intended to fit the `::Logger` interface, and the default logger
+    (`WarnLogger`) is a subclass of `::Logger` that passes through to
+    `Kernel.warn`.
+
+    - Further consideration has changed cache load messages from `warn` to
+      `error` and deprecation messages from `warn` to `debug`.
