I wasn't aware that it's been that long since we did a release of edtFTPj/Free.  I queried my colleague (who's in charge of releases) about it and he said that he feels that, although there have been many changes in the commercial version, edtFTPj/PRO, the code-base for edtFTPj/Free has been largely unchanged through this period.  I suppose we will do one soon.  If you e-mail us (support@enterprisedt.com) we can send you the latest code.
