+If you desparately want the old behavior, please add the following to `/etc/plexupdate.conf` :
+
+```
+if [ -f ~/.plexupdate ]
+  source ~/.plexupdate
+fi
+```

+## Do I have to use the `extras/installer.sh` ?
+
+Of course not, anything you find under `extras/` is optional and only provided as a easier way to get `plexupdate.sh` up and running quickly.
