GNU nano 8.0 released

Restricted mode is frankly not very useful. If you want to let somebody edit a file, the proper way to do it is to copy the file into /tmp with permissions set so that they can read and write it, let them edit it in-place with an unprivileged editor, and then copy it back. If you need to do something more elaborate than that, then you probably should be reaching for a container or VM, not restricted mode.
