Version 4 adds so many things it's hard to keep track of, but I'll try to list what I remember below:

Additions:
- Added new /partychat bugreport command for easier troubleshooting when errors occur.
- Added new message configuration for GUI messages.
- Added easier support for more languages.
- Added more config options and a new config file for command configuration.
- Added ability to block inappropriate words in party chat.

Changes:
- Switched from SQLite database to JSON for party storage.
- Rewrote the entire plugin to be cleaner.
- Changed in-text formatting for hover and click events.

And many more!
Try the new version out for yourself to see all that's changed. It should retain the same look and bring over existing parties.
