The most important most obvious and easy and/or game breaking bug fixes first.
This is a huge patch, so the notes have been broken into sections based on themes. Merry (if not slightly late) Xmas.
This update takes the form of a list because I like lists. In it is every big new thing going into the next patch, followed by some paragraphs talking about what they are and how complete they are. The patch will be ready when all of these items are complete.
