Taking a look at the ZQuest.txt file, some of the information is outdated. For example, some of the features included in previous builds are no longer included in the current version, such as the Weapon Animation Fix Rule, which was never implemented, and the ability to flip screens and maps horizontally and vertically, although to be blunt, I don't think the ability to flip screens and maps should have ever been removed in the first place, because other than having to rearrange a few combos, I saw absolutely nothing wrong with those features whatsoever, and I kind of miss them too. Fortunately, I still have beta 18, which still has those features. However, there are some features in the current version that are not in some of the previous versions, such as newer quest rules like Log Script Errors to Allegro.log and Draining Rupees Can Still Be Spent, and the Compatibility rules.
