    ///  - Perform a diff between latest supported version in MCC and new stable version to support on https://wiki.vg/Protocol
    ///  - If there are any changes in packets implemented by MCC, add MCXXXVersion field below and implement new packet layouts
    ///  - Add the packet type palette for that Minecraft version. Please see PacketTypePalette.cs for more information
    ///  - Also see Material.cs and ItemType.cs for updating block and item data inside MCC
