- URL parser rewritten from using regular expressions to be a finite state machine. Greatly improves performance by guaranteeing linear time parsing and fixes long parse times in Safari in particular (which seems to have a slow regex backtracking implementation).
- IP addresses are now linked without a scheme like 'http://' prefixed to it.
urls.ipV4Matchesoption controls this behavior.
