 Upgrading
 =========
 
-From 0.6.3 or older
------------------
-
-- Apache's `X-Request-Start` header is now recognized, which if present
-  will trigger the default `wait_timeout` behavior (unless you have changed
-  those settings or disabled it).
-
-  Please review `wait_timeout` behavior in [doc/settings.md](doc/settings.md#wait-timeout).
-
-  TL;DR -> set `wait_timeout` to `0` or `'false'` to disable it and maintain
-  your Apache setup's current behavior.

 From 0.4 or older
