 * Document secret `HOOK_BANNER`, the first hook point before the banner
+* Document slightly confusing `initctl reload foo` command.  It does

+* Log changes; all instances where previously the `basename cmd` of a
+  service was used to identify the service, now the proper `name:id` is
+  used instead.  Meaning, a service without a custom `:ID` or `name:`
+  will display the same as before, but with any of those customizations

 * The `name:id` tuple is now more consistently used in all log and debug
