The development of this SABnzbd-based version of LottaNZB began over 1 year and 8 months ago, when it became more and more clear that the original HellaNZB backend was not a viable choice for the future. During this time, a couple of suggestions related to SABnzbd's API have been implemented by the SABnzbd crew. The SABnzbd developers really deserve credit for the great piece of software they've created! Compared to previous versions, the user interface of LottaNZB has been polished considerably and the setup process has been made smoother. This is how the main window looks like:

Packages for both Ubuntu and Fedora are available, as well as a source tarball. Please note that 0.6 is the very first release of LottaNZB which is based on SABnzbd and even after months of testing by the developers and people who have used the daily builds, you might still encounter bugs or crashes. For instance, some users are reporting random crashes due to segmentation faults, which are still being investigated. You’re encouraged to report any bugs you find at https://bugs.launchpad.net/lottanzb/+filebug
I'd love to hear from you what you think about it and how it could be improved. Have fun with LottaNZB!
