So, Puzzle Pirates gets an update about every few weeks adding new features. This latest one finally added some of the aspects involved in war between flags. Vessels can now be sunk. If you're on a vessel that goes down, you have a small chance of being injured. Injuries come in the form of getting a peg leg, hook, or eye patch.
The other nice addition this time is that tournaments support has been improved now for those that want to have sword or drinking tournaments. The previous incarnation wasn't very workable, so really, it's like a new feature.
I'll post future additions in this thread.
