Changes aren't huge. If you didn't change existing classes you can save new versions to a package with different name, then add it to your session and delete/copy/paste new version of classes over old ones. If you modified them with your own patterns then I don't think it can be done without some manual merging.

Changes that I remember:
- expanded big ass "my damage" regex to not color "hitting a porcupine".
- added another color "Blood". Currently it hightlights rager's thirst.
- added/updated some defensive moves.
- fixed incorrect/obsolete patterns I found.
- merged some spell/skill/malediction/etc messages to reduce the number of triggers.
- maybe something else.
