 ### Additions
-
-- Added ability to rename PC Boxes by clicking on the name of a box
-- Added ability to set wallpapers per PC Box by clicking the button right to the box name
-- Added sorting by Name, Level and type by clicking the button left of the box name (shift reverses order)
-- Added filtering/search functionality in PC UI, which also supports pokemon properties (e.g. shiny=yes shows all shinies)
-- Added /changewallpaper <player> <boxNumber> <wallpaper> command to change a wallpaper through commands
-- Added /renamebox <player> <boxNumber> <name> command to rename a PC box through commands
+- Added ability to rename PC Boxes by clicking on the name of a box.
+- Added box options buttons for boxes, toggleable by clicking the right icon button in the bottom bar.
+  - The button on the right allows for changing the box wallpaper.
+  - The option buttons on the left side allow for sorting the box by name, level, Pokédex number, gender, and type. Shift clicking allows for sorting in reverse order.
+- 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.
 
 ### Developer
+- Added `RenamePCBoxEvent.Pre` and `RenamePCBoxEvent.Post` events to prevent players from renaming a box or changing their input.
+- Added `ChangePCBoxWallpaperEvent.Pre` and `ChangePCBoxWallpaperEvent.Post` to prevent players from changing wallpapers or changing their selection.
+- Added `WallpaperCollectionEvent` which gets called when clients connect to a server, allowing the server to handle which of the client-found wallpapers it's allowed to move (collected wallpapers can be removed for example to make it "vanish" client-side).
+- Added `WallpaperUnlockedEvent`.
+- Renamed `SetPCBoxPokemonPacket` and the respective handler to `SetPCBoxPacket`.
 
-- Added RenamePCBoxEvent.Pre/Post events to prevent players from renaming a box or change their input
-- Added ChangePCBoxWallpaperEvent.Pre/Post to prevent players from changing to a wallpaper or change their selection
-- Added WallpaperCollectionEvent which gets called when clients connect to a server, allowing the server which of the clients found wallpapers it's allowed to move (collected wallpapers can be removed for example to make it "vanish" client-side)
-- Wallpapers are loaded from `assets/<namespace>/textures/gui/pc/wallpaper/` and all wallpapers in this folder are available to the client to  choose by default
-- Renamed `SetPCBoxPokemonPacket` and the respective handler to `SetPCBoxPacket`
+### Addons
+- Added Flows for `player_tick_pre`, `player_tick_post`, `advancement_earned`, `right_clicked_entity`, `right_clicked_block`, `player_died`, `wallpaper_unlocked`.
+- Flows now have `q.` for any context properties in addition to the `c.` properties, making it a bit more convenient when calling other scripts from Flows.
+- Added `unlockable_pc_box_wallpapers` datapack folder for wallpapers that need to be unlocked before they're usable.
+- Wallpapers are loaded from `assets/<namespace>/textures/gui/pc/wallpaper/` and all wallpapers in this folder are available to the client to choose by default.

 ### Changes
 - Renamed `chargeGainedPerTick` config to `secondsToChargeHealingMachine`.
+- Made Blocks of Gold count as Big Nuggets when held by a Pokémon (for Fling functionality)
+- 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.
 
 ### Fixes
 - Fixed Particles sometimes facing the wrong direction (looking at you, Swords Dance)
@@ -34,6 +38,12 @@
 - Fixed owned Pokémon sometimes being un-interactable after the player relogs fast
 - Fixed field name in evolution requirements for Spewpa Pokeball.
 - Fixed LevelUpCriterion logic to correctly check that the Pokémon is a preEvo.
+- Fixed `hide_additional_tooltip` vanilla flag not properly hiding tooltips on pokerod and bait items
+- Fixed NPCs using Pokémon outside of their pool when a Pokémon name had a typo.
+- Fixed an issue with datapacked species features not being applied properly when relogging.
+- Fixed Pokémon marked as silent still playing shiny sounds and effects.
+- Fixed an issue with newer versions of Fabric API where underground Pokémon were spawning in The End.
+- Fixed spawning not working well when you're at high points surrounded by lower altitude spawning areas, such as flying.
 
 ### Developer
 - A finished battle now has winners and losers set inside of `PokemonBattle` instead of them always being empty.
@@ -44,9 +54,10 @@
 - Removed the NbtItemPredicate class, all the mod usages now use the vanilla item predicate solution, this causes breaking changes on Fossil, HeldItemRequirement & ItemInteractionEvolution
 - Renamed Cobblemon's creative tabs to start with "Cobblemon: " to distinguish Cobblemon's tabs from tabs for other mods.
 - Various items now have a rarity value.
-
-### Changes
-- 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.
+- Reworked observable handling in `Pokemon.kt` to cut down on RAM usage and clarify the file.
+  - Note: This will break mods that used our observable functionality there or in MoveSet, IVs, EVs, or BenchedMoves. 
+  - Using `Pokemon#onChange()` is now the way to mark a Pokémon as needing a save.
+  - Using `[Pokemon].changeObservable` is now the way to get an `Observable` for any save-worthy changes.
 
 ### MoLang & Datapacks
 - The following usages for item predicates can now use item conditions like advancements do, you can learn about them in the [Minecraft wiki](https://minecraft.wiki/w/Advancement_definition#minecraft:filled_bucket)

   - The `fossils` for a fossil entry
 - Added MoLang flows for `poke_ball_capture_calculated`, `evolution_tested`, `evolution_accepted`, `evolution_completed`

+- Fixed species additions not being capable of changing implemented status.
