 - Added filter functionality in PC UI, which supports `PokemonProperties` (e.g. `shiny=yes` shows all shiny Pokémon).
 - Added `/changewallpaper <player> <boxNumber> <wallpaper>` command to change a box wallpaper through commands.
 - Added `/renamebox <player> <boxNumber> <name>` command to rename a PC box through commands.
+- Added IVs and EVs stat displays in PC.
 
 ### Developer
 - Added `RenamePCBoxEvent.Pre` and `RenamePCBoxEvent.Post` events to prevent players from renaming a box or changing their input.

+- Added `/transformmodelpart (position|rotation|scale) <modelPart> <transform: x y z>` command that can add transformations to a pokemon's model part.
+  - The player executing the command must be facing the target pokemon entity. Transformations are not persistent and will revert when resources are reloaded.
+- Added lang keys for all moves and abilities up to Generation 9.
+- Fixed Moon Ball moon phase logic to actually work correctly
+- Added `translucent_cull` boolean option into resolver's layer to allow for translucent textures with culling

 ### Changes
 - Renamed `chargeGainedPerTick` config to `secondsToChargeHealingMachine`.
 - Made Blocks of Gold count as Big Nuggets when held by a Pokémon (for Fling functionality)
+- Players can now eat Sweet and Tart Apples, Whipped Dreams, and the Alcremie Sweets.
+- Updated Sweet and Tart Apple sprites
+- Updated the following recipes: Air Balloon, Assault Vest, Binding Band, Black Belt, Blunder Policy, Choice Band, Choice Scarf, Cleanse Tag, Covert Cloak, Destiny Knot, Eject Button, Expert Belt, Focus Band, Focus Sash, Magnet, Metronome, Muscle Band, Power Anklet, Power Band, Power Belt, Power Bracer, Power Lens, Power Weight, Protective Pads, Protein, Punching Glove, Reaper Cloth, Rocky Helmet, Room Service, Sachet, Safety Goggles, Silk Scarf, Spell Tag, Utility Umbrella, Weakness Policy, Zinc
+- 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.
