 * `erikarvstedt`_ contributed a pull request (`#328`_) to add ``--noreload``
   to the default server start process.  This helps reduce the load imposed
   by the running webservice.
+* Through some discussion on `#253`_ and `#323`_, we've removed a few of the
+  hardcoded URL values to make it easier for people to host Paperless on a
+  subdirectory.  Thanks to `Quentin Dawans`_ and `Kyle Lucy`_ for helping to
+  work this out.
