Detailed patch notes for Conquer Online, from version 2.0 to 3.0, and excluding patches that only add new servers, new temporary events or fix bugs. When targeting a patch, take the highest before a feature you do not want. Also, note that † denotes protocol changes, but only patches between 5016 and 5078 are identified because that's the range I personally target in COPS X Emulator.
Later patches (above 5100) are a bit less exhaustive, because at that point, TQ were releasing a lot of daily quests, a lot of boxes and other pay-to-win content. So it would be quite bloated... I'm also less interested in those.
