SABnzbd 0.5.0 RC3 is released

Thursday, January 21st, 2010

The journey to the 0.5.0 Final release is nearing the end. Thanks to the feedback from our more adventurous users, a lot of small and some bigger issues have been solved. There were no public RC1 and RC2, because our test group reported some issues that we wanted to solve first.

SABnzbd 0.5.0 RC3 is available for download from

      Progress in 0.5.0 Beta

      Monday, January 4th, 2010

      We finally managed to find out why some people complain about intermittent and sometimes frequent timeouts on their server connections.

      It turns out that on some systems for some Usenet providers, DNS resolving takes very long.
      On Linux systems it seems worse than on Windows.
      It’s probably a combination of the OS and the network library we use.

      The download section is designed under the assumption that DNS resolving takes a few seconds. If it starts taking between 10 and 30 seconds, already established connections will time out.
      This is especially true for unresolvable addresses (like those of free IPV6 servers that are often off-line).

      Anyway, discovery is 50% of the solution. It will take a few days to work out (and test) a proper work-around for this. As soon as it’s ready there will be a new Beta.

      After this is solved we’re very close to a final release of 0.5.0.
