Please be aware that due to some heavy internal changes this version
requires a full install. Online update just won't work. Sorry about that.
Also, please be sure to backup any old patches you have before
installing, and, if you've made a track, bounce the karmafx parts to
audio to make sure you don't loose anything.If you run into bugs,
please report it to: firstname.lastname@example.org, and I'll provide a fix ASAP !
