====== PoseStack -> GuiGraphics ======
All events related to gui rendering in Architectury API now all take in ''GuiGraphics'' instead of ''PoseStack''.

====== LootTables -> LootDataManager ======
''LootEvent'' now takes in ''LootDataManager'', as ''LootTables'' no longer exist.

====== Migrate creative tabs to the registrar system ======

Tip: You can also take a look at the [[api:creative_tabs|new Creative Tabs docs]], as it details how to create the tab in 1.20 as well.

Since Minecraft now registers creative tabs as a regular registry, previous ''TabSupplier'' interfaces used to defer creative tabs for Forge have been removed. All deferred methods now take in a builtin ''CreativeModeTab'', or ''ResourceKey<CreativeModeTab>'' or ''DeferredSupplier<CreativeModeTab>'' that ''RegistrySupplier'' now extends.

Which means to create a creative tab now, you can use the deferred register:
<code java>
public static final DeferredRegister<CreativeModeTab> TABS = DeferredRegister.create(TestMod.MOD_ID, Registries.CREATIVE_MODE_TAB);

public static final RegistrySupplier<CreativeModeTab> TEST_TAB = TABS.register("test_tab", () ->
            CreativeTabRegistry.create(Component.translatable("category.architectury_test"),
                    () -> new ItemStack(TestRegistries.TEST_ITEM.get())));
</code>

The ''TEST_TAB'' here acts like a regular register supplier like any other registry entry, moreover, ''arch$tab'' methods now take in ''DeferredSupplier<CreativeModeTab>'', that you can directly pass them in.
