No new features, just bugfixes and refactoring. Where possible I'm trying to simplify the code to make it work more consistently and easier for new developers to understand. There are still a lot of anti-patterns in the code base which make my fingers itch, but I do want to get this 1.9.4 release stable enough for production use, so I'm holding off some of the bigger changes for 1.9.5 and beyond.
