 ## [1.7.2 (MONTH Xth, YEAR)](#1-7-2)

 ### Additions
- Added riding statistics: `Distance by Pokémon on Land`, `Distance by Pokémon in Air` and `Distance by Pokémon in Liquid`.
- Added the Partner Mark, which party Pokémon have a very small chance to earn as the player walks, provided they have enough friendship.
- Added trades for Saccharine Saplings, Hearty Grains, Chipped Pot, and Masterpiece Teacup to the Wandering Trader.
- Added brewing recipe for Throat Spray.
- Added mood particles! Pokémon now visually react to certain actions:
-    - Angry particles when attacking a mob.
-    - Annoyed particles when a player tries to feed them while they’re already full.
-    - Sweat droplets when they run out of stamina while being ridden.

 ### Changes
- Ride sounds have been separated into stereo for passengers and mono for other players. Riding will now sound more spacious.

 ### Fixes
 - Fixed orientation not getting reset after crashing while flying and getting back on the Pokémon.
 - Fixed Furfrou not being trimmable on NeoForge.
- Fixed shiny Pokémon not respecting the silent flag on spawn.
 - Fixed honey from Saccharine Leaves being harvestable at less than the max age.
 - Items given from interacting with Saccharine Leaves are placed in the active hotbar slot if possible.
 - Fix all Pokémon being saved to chunks and never despawning.
- Fixed PokeSnacks crashing if there was no available spawn.
- Fixed Pokémon spawn influences not being specific to regional forms
- Fixed crashing when viewing another player in spectator mode
- Fixed missing apricorn textures for Adorn blocks
- Fixed crashing when riding due to malformed json file, instead resetting it
- Fixed mochi items consuming two items at a time
- Fix item interaction sometimes not working properly when playing on servers.

 ### Developer
- Changed the `owner` parameter in the `OwnerQueryRequirement` interface from `ServerPlayer` to `Player`. This method is now also called on the client to verify whether a Pokémon interaction succeeded, so make sure to update your implementations to handle both server and client contexts. 

 ### Molang & Datapacks
- Ride sounds can now be set as exclusive to passengers
- Ride sounds no longer play when submerged unless specified with a new setting
