Other breaking changes: SpectatorInventoryView was changed from a class to an interface in order to support Bukkit's source-incompatible change (they converted InventoryView from a class to an interface). API consumers that made use of the SpectatorInventoryView, EnderSpectatorInventoryView or MainSpectatorInventoryView classes will have to recompile their code against this new version.
