-    As `{admiral}` is still evolving, functions/parameters may need to be removed or replaced over time. In such cases, the function/parameter will enter the following 6-month deprecation cycle:
-
-    * In the first release (0-3 months), there will be a warning issued if you use the function/parameter, but it will still be available to use.
-    * In the following release (3-6 months), an error will be produced if you use the function/parameter.
-    * Finally, from the 3rd release (6 months) onwards, the function/parameter will be removed from `{admiral}` and its documentation completely.
-
-    *Note: Guidance on replacement functionality can be found in the warning/error message produced or in the function's documentation.*
-
-    Below, you can find a list of functions in the process of being deprecated:
+    Superseded functions have been replaced with better functions. However, we
+    will not be removing these functions from `{admiral}`.  We do strongly
+    encourage you to make the switch over.
