28 changes by PROTOCOL_VERSION:
31 Base for writing changes here
36 Add TOCLIENT_CRAFTITEMDEF
38 Obsolete TOSERVER_CLICK_ACTIVEOBJECT
39 Obsolete TOSERVER_GROUND_ACTION
41 Make players to be handled mostly as ActiveObjects
43 Only non-cached textures are sent
46 Obsolete TOCLIENT_TOOLDEF
47 Obsolete TOCLIENT_CRAFTITEMDEF
48 Compress the contents of TOCLIENT_ITEMDEF and TOCLIENT_NODEDEF
50 Digging based on item groups
53 ContentFeatures and NodeDefManager use a different serialization
54 format; better for future version cross-compatibility
58 Version raised to force 'fly' and 'fast' privileges into effect.
59 Node metadata change (came in later; somewhat incompatible)
61 TileDef in ContentFeatures
64 TOCLIENT_INVENTORY_FORMSPEC
67 TOSERVER_INVENTORY_FIELDS
69 TOCLIENT_DETACHED_INVENTORY
71 InventoryList field "Width" (deserialization fails with old versions)
73 Added transfer of player pressed keys to the server
74 Added new messages for mesh and bone animation, as well as attachments
75 GENERIC_CMD_SET_ANIMATION
76 GENERIC_CMD_SET_BONE_POSITION
77 GENERIC_CMD_SET_ATTACHMENT
79 Serialization format changes
