you are welcome to everyone, but the real thank you should go to nrapallo ! he did all the work making the dictionary. you might toss a little karma his way when you download.
i am not aware of a more recent edition available for the moment but i hope there will be one soon (i would buy an epub version of a recent dictionary in a heart beat). there are other free / open source dictionaries but i'm not sure whether they've been made available in epub format, for instance the GNU open source collaborative dictionary
available on mr but only in mobi format for the moment, and i believe the StarDict site has many dictionaries available but in their specific format ; i'm not sure how easy it would be to convert them.
if anyone DOES find other dictionaries, PLEASE post a link to them in this thread !
i will do the same of course.
