    Version 3.18.1
    
    * No longer stash environment in $XDG_RUNTIME_DIR/gnome/environment
    * Set SSH_AUTH_SOCK explicitly for wayland sessions
    * Set LC environment variables up front, so g-s-d doesn't have to do
      it and hand it back to us later
    * Set IBus environment variables too
    * Translation updates
