Dear adddthis_matt,
good news. Looking forward to a new version.
I′m not that firm with WP to install a newer/older Version of something. Better not to try&error in WP, its behaviour is to unpredictable.
I dont′s bring in any kind of tags, actually, I don′t know what that is, so I think no.
thanks for your help and have a good time.
w/regards
Michael
