Get latest bugfixes

Weka is actively developed, that means that bugs are fixed and new functionality is added (only to the developer version) all the time. Every now and then (about every 6-12 months), when there was a sufficiently large number of improvements or fixes, a release is made and uploaded to Sourceforget.net.

If you don't want to wait that long, you can get the latest source code from Git and compile it yourself.

1. obtaining the source code from Git, either book or developer version
