You gotta decide.... 1.31. seems to work OK although there are always some issues reported (look around on the board). If you decide to go to 1.3x you need the new Shareport 1.10 (deinstall the old version first and remove all pieces/references). Also, do not use the saved config but set it up manually.
If you have no issues you can stay with this version. You can always upgrade to 1.3x later on.
