1.4.2.0 has added several new hooks, Added two new modifiers: Attack Blasting: When attacking an entity, it will cause the entity to explode but consume more tool's durability. Ender Speed: Similar to the modifier with the same name in Tinkers' Construct 2, but only retains high-speed flight. After attacking a target, the final damage is almost unaffected by high-speed flight. Fixed a bunch of null pointer bugs that caused game crashes in 1.4.1.0.
1.4.1.0 fixes the logical error introduced during the bug fixes in 1.4.0.6, specifically the bug where unbroken arrows caused the game to freeze due to piercing enchantment or modifier. Two new hooks have been added to control projectile entity speed and projectile entity flight respectively.
1.4.0.5 fixes the bug where the modifier slots were not returned when removing modifers added by Tinker Transplant in the Modifier Worktable, fixes the bug where a crossbow with the "Reload Tinker Arrow" modifier couldn't fire the loaded Tinker Arrow due to a null pointer when reloading the game after fully exiting, and fixes the null pointer crash that occurred when reloading the game while Tinker Shuriken and Tinker Arrow entities were still in flight.
