• Breaking: functions built on count_items (clear_and_execute_single, clear_and_execute_multiple, maintain_item_count, convert_items_to_xp) now take a {namespace} parameter as well;
• Breaking: dfl:child/smelt renamed to dfl:tick/smelt_item and dfl:tick/smelt renamed to dfl:tick/coal_smelt, both with adjusted parameters;
• Breaking: removed the dfl:lib/spawn_dummies function;
• Breaking: removed the tick entry point function and the minecraft:tick tag;
