Release Notes: A dynamically-generated tabbed preferences window was added, including general options such as shadow and font and per-game options. The code was updated for RubyCocoa-0.11.1. Misspelled API names were fixed. For example, "centerized" was changed to "centered". The Tank-0.3.8 add-on game doesn't work on 0.4.0, so Tank-0.4.0 should be used instead.
