Panic has announced the release of Unison 1.7.1, a significant update to its Usenet newsreader for Mac OS X. Unison 1.7.1 offers many improvements and fixes, but most importantly adds binary uploading / posting, a much-requested feature. Users can now post a file to Usenet with a single click, including the ability to easily split large files into smaller files, and automatically create PAR2 recovery sets if desired. Panic also announced that users who purchase Unison before December 30, 2005, will be automatically entered in a drawing to win an extremely rare Panic iPod nano — a 4 GB white iPod nano with the Panic logo factory engraved on the back.
