everything is working fine with libtorrent 1.1.1 here (had problems with 1.1.0), except for geoip. there is a patch for it so i'm not sure if you want to apply it to deluge 1.3.13 to have it fixed in stretch before freeze.
http://dev.deluge-torrent.org/ticket/2861 "Deluge currently uses libtorrent to get GeoIP data. In libtorrent-rasterbar 1.1+ GeoIP functionality has been removed so a direct implementation is required. This patch uses python-GeoIP bindings for the job (rewriting it using pygeoip or ctypes is not a problem). On libtorrent-rasterbar 1.0 or older new behaviour is to first try libtorrent's implementation then if failed to try bindings."
