What is SABnzbd?

SABnzbd is a free/open-source cross-platform binary newsreader written in Python.

It simplifies the process of downloading from Usenet dramatically, thanks to its friendly web-based user interface and advanced built-in post-processing options that automatically verify, repair, extract and clean up posts downloaded from Usenet. SABnzbd also has a fully customizable user interface, and offers a complete API for third-party applications to hook into.

0.7.11 bug fix release

Posted by shypike on February 7th, 2013 at 3:45 pm

Due to an error introduced in 0.7.10, verification of some NZB can seemingly take forever.
In order to support the current wave of oddly named files in NZBs, we changed the way that par2 verification works. Unfortunately, due to an error, all posts are treated this way. That’s OK for your average NZB, but some NZBs contain multiple sets of rar&par files. The bug means that the verification of each set will parse all files, potentially resulting in much longer verification/repair times. This is especially noticeable on slower systems.

The second bug occurs when some (rare) Usenet servers start sending odd articles. SABnzbd handles these as containing valid data. The result can be that downloads are corrupted beyond repair.

The third bug solved was just a nuisance. The Sort functions would not rename files when the RAR where they come from, contains an extra folder level.

0.6.9 maintanance release

Posted by shypike on September 10th, 2011 at 6:01 am

We just published a new maintenance release, 0.6.9, for the 0.6.x series.
It should be the last one for this series.
Now we concentrate on getting 0.7.0 ready for its first public Alpha.

Finally a 0.6.0 Beta

Posted by shypike on February 20th, 2011 at 4:03 am

We’ve been working on this for a year, during all the 0.5.x releases.
The release test group (with their infinite patience) has been a major contributor for this.
We are very proud on the end result.

Some highlights:
– A revamped Plush skin that we now promote as the primary UI
– Repair of failed jobs
– Stability of the queue
– True Windows Service support
– Overhaul of the RSS user interface
