You can find the full list of changes here:
Download the plugin from the main webpage:
Please 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 immediatly, and I'll provide a fix ASAP !
Simply select "Check for updates now" in the right-click menu, and follow the instructions.
Note however, that this only updates the core plugins. Patches, etc. from the new version will not be downloaded. To get those, you have to download the full installer.
Let me know if this causes any problems.
