Unison is a carefully crafted, genuinely revolutionary Mac OS X Usenet newsreader. It offers all the expected newsreader functionality: easy-to-navigate threaded discussions, the ability to ignore annoying posters, multiple signature management, and easy, Mail-like posting with spell checking and all the trimmings. It also goes much further than any other Usenet client, starting with a unique four-view interface that lets you view and work with Usenet group content in four distinct styles: messages, files, images, or music. It lets you preview MP3 files directly off a Usenet server, view images in an elegant iPhoto-like thumbnail view, prioritize transfers with a flexible downloads manager, find Favorites quickly with a categorized column-view interface, smartly group files into metagroups (such as songs into albums), and show the download status in the dock.
New features in Unison 1.6 include: Added support for SSL (secure) NNTP servers. Added automatic MacBinary decoding. Loading message overviews is much faster now. Unison takes less memory, less disk space, and runs much faster overall. File grouping is smarter now. Printing is much improved. Download resuming now works better, picking up where it left off. Text encoding support is now much improved. Holding down "Option" and clicking Download sends files to top of queue. Added new groups to the list of default Favorites.
