as seen at gnome.org: "This version is only a minor bug-fixes release." Btw I've been using this a bit and I'm getting ready to let go of Endnote for good. Wooh-hooh... :)
bp is a freely licensed perl package for manipulating and accessing bibliographic information. It supports bibtex, refer, endnote, procite, inspec, medline and other formats for input/output/conversion. I emailed the author as the bp homepage does not seemed to have changed in two years... will post any response as a comment.
