Subject: Add an ACL list for users connecting to the tmux socket. Users may be
 forbidden from attaching, forced to attach read-only, or allowed to attach
 read-write. A new command, server-access, configures the list. tmux gets the
 user using getpeereid(3) of the client socket. Users must still configure
 file system permissions manually. From Dallas Lyons and others.
