*** Emacs and emacsclient now default to "$XDG_RUNTIME_DIR/emacs"
as the directory for client/server sockets, if Emacs is running
-under an X Window System desktop that sets the 'XDG_RUNTIME_DIR'
+on a platform or environment that sets the 'XDG_RUNTIME_DIR'
environment variable to indicate where session sockets should go.
To get the old, less-secure behavior, you can set the
'EMACS_SOCKET_NAME' environment variable to an appropriate value.
