+- Players can now eat Sweet and Tart Apples, Whipped Dreams, and the Alcremie Sweets.

+- Added alternate ingredient options to the following recipes: Cell Battery, Charcoal Stick, Dragon Fang, Miracle Seed, Mystic Water, Never Melt Ice, Twisted Spoon, Damp Rock, Heat Rock, Icy Rock, Smooth Rock
+- Grouped together some recipes within the Recipe Book. Groups include: the seven basic Poké Balls, the seven basic Ancient Poké Balls, Gilded Chests, Pokedexes, and the Weather Rocks.
+- Updated some item tags to better integrate behaviours between Cobblemon, Vanilla Minecraft, and other mods
+  - Removed Cooked Meat, Raw Meat, Protein Ingredients, and Zinc Ingredients, the first two are now using `c` namespace tags, the latter have better integrated use of tags within their recipes which removes need for custom tags.
+  - Added our seeds tag into `#c:seeds`, which is now made use of for the Miracle Seed recipe. 
+- Tweaked the Natural Materials Vanilla file to fit with the changes to tags
 - Substantially optimised spawning checks mainly by front-loading biome filtering.
 - When using the `cobblemon` or `generation_9` capture calculators a critical capture with a single shake will always play for successful captures when you've already registered the Pokémon as caught in your Pokédex.
 - Improved the performance of saving Pokédex and player data.
+- Pokémon hitbox now scales with entity attribute `generic.scale`.
+- Removed Shulker aspect and replaced it with cosmetic_item-shulker_shell.
+- Shulker shell Forretress is now a cosmetic rather than a special evo and thus all shulker Forretress will revert back to normal until a shulker shell is put in their cosmetic slot.
+- Updated `doPokemonSpawning` gamerule to support per-dimension configurations.
+- The Pokedex now displays a form name of a "normal" Pokémon for when the base form is still a named form.
+- Improved the zoom functionality of the Pokédex Scanner by giving the levels logarithmic scaling.
+- Added a subtle rotation effect to the Pokédex Scanner's wheel when zooming.
+- Improved parity with vanilla mobs' drop behavior; loot and XP drop on death instead of after the entire death sequence finishes.
+- Quirk animations no longer play in the battle GUI since they were pretty distracting.
