SABnzbd Releases Version 2.3

SABnzbd continues to refine their popular Usenet browser.  The SABnzbd 2.3 release includes an update to SABYenc and performance improvements on CPU limited devices. Version 2.3 was released a few hours ago.  You can choose whether you want to wait for any bugs to be flushed out.  We’re comfortable with SABnzbd releases and this isn’t a beta or RC.  In this case you can expect fewer bugs since it’s a full release. We haven’t heard of any major issues with the yet. As of Thursday afternoon, SABnzbd 2.3 has been downloaded 2,693 times.  Those who haven’t tried SABnzbd in the past are welcome to grab the latest release from their downloads page or learn more about the project at

SABnzbd 2.3

SABnzbd is one of our favorite newsreaders along with NZBGet, Newshosting client, Newsbin and NewsLeecher.  All of them do a great job at downloading from Usenet.  If your goal is text newsgroups we would suggest Newsbin.  SABnzbd focuses on binary files.  The open-source client runs as a web server on your system.  You can access it through your favorite web browser.  They have versions available for Windows, Mac and Linux.

Since SABnzbd is open-source and has such a large following you will find a number of cool add-ons and services like CouchPotato, Sick Beard, Sonarr and SABMobile for iOS and Android devices.  Check out the SABnzbd forum to learn more about these add-ons and others available for the client.

Who said Usenet isn’t popular?  SABnzbd continues to grow and has now passed 9 million downloads.  Having so many popular extensions integrated with the Usenet browser will only help the project continue to grow.  If you have any questions or need help getting started the SABnzbd team has some nice guides.  The forum is also a great place to ask questions and learn about all the custom add-ons.
