Vanilla Refresh
The server is equipped with a datapack called Vanilla Refresh
These docs are partially pulled and edited from the Vanilla Refresh Datapack page
Health Displays
Mobs will have their health displayed in the action bar (text directly above your hotbar).
Players will have their health displayed below their nametag.
Daycounter
After someone sleeps and the it becomes morning, there will be an animation displaying the current Minecraft day in your hotbar.
This is mostly a cool little thing, it does not show actual playtime in Minecraft days (days still advance even when no one is online)
Any day that is a multiple of 100 will play a special milestone animation.
Homing experience orbs
If you kill a Ghast, the experience orbs will fly towards you instead of them falling into lava.
Crafting sounds
When you craft something in a crafting table, it will play a woody crafting sound.
Certain conditions like the number of items crafted at once and the type of item might play different sounds!
A small particle effect that is mostly only visible to other players will show on top of a crafting table when something ins crafted!
Crops drop xp
If you break crops, there is a small chance that they will give a small amount of experience. This will not happend if you use effortless harvest. This is intentional because getting a small amount of xp from farming is a very early game feature.
Jukeboxes override game music
It's pretty self explanitory. Minecraft music will be stopped for you if you are in range if a playing Jukebox so it won't overlap with the Jukebox.
Loyalty tridents stay loyal in the void
Instead of a loyalty trident getting killed if it falls in the void, it will instead bounce off of y level 0 to come back to you!
Baby zombie changes
Health of baby zombies has been halfed, but they can now sprint jump!
Better and universal death sounds
Instead of the classic "splat" sound that Minecraft plays when you die, a special death sound will play based on how you died. This death sound is also played to all players to make your death more announced. Playing death sounds to all players may be considered annoying, please tell me what you think!
Better armour stands
The datapack page explains this better than I could so I'll just quote them.
[Armour stands] now have arms, and a bunch of different poses for you to display your armor, items, and weapons
Power a lever near them to swap their pose
You can add an item to an armor stand then right click it with a tripwire hook to turn it into a tool rack. They'll hook onto to the wall the armor stand is against, perfect for displaying your swords and tools.
Drop ladder
Again, quoted from the datapack page
Found yourself a big drop in a cave below you? Press sneak whilst on a ladder to extend its length down and create hanging ladders allowing you to descend down.
Totems work in the void
The datapack page also explains this very well
Falling into the void with a totem in hand/offhand will enter you into a controllable float mode of levitation till you reach land.
Player's heads drop on death
It is exactly what is says
Silence mobs with echo shards
Let's see what the datapack page has to say...
Drop an echo shard on top of a mob to silence it. You can get that echo shard back by placing water on top of the mob, or directly killing the mob.
F3 Day offset
Java Minecraft's day counter starts at 0 instead of 1, this is a little weird because you have to remember to add 1 to the day count to get the actual number of days that have passed. This simple tweak adds 1 to the day counter in the F3 screen.
Wither head drops
When you defeat the wither, it will drop a wither head as a trophy.
Equipable banners
Ever wanted to wear a banner on you head like a Pilliger captain?
-
Hold a banner in your hand
-
Crouch 3 times in quick succession (on Java click shift 3 times quickly)
Additional player animation
Quoted from the datapack page
New player animations for leveling up and splashing on water at different heights!
Special blocks have special animations
Quoted from datapack page
Blocks including Enchanting Tables, Brewing Stands, Beacons, Wither Skeleton Skulls, Dragon Eggs, and Jukeboxes will have improved block animations. Immersion x100!
Jukebox animations can be enhanced even more by placing a note block below a jukebox
Opening enderchests will also shoot out a cool ring of purple particles
Event subtitles
Quoted from datapack page
Major events like summoning the wither and entering the end will display a dramatic title on screen
When finding a new biome, it'll display the name/category name of the biome as a title on screen
Trimmed Armored Piglins
Quoted from the datapack page
Armored piglins now have a chance of spawning in with their armor pieces trimmed. About 8% of all piglins will have trimmed armor, and bastion remnants will have 16% of all piglins with trimmed armor.
Low Health Sound
Quoted from the datapack page
If you take damage at low health, a heartbeat amethyst sound will play once
Path Sprinting
Quoted from the datapack page
Paths now give you speed as an incentive to place paths around your towns
Armour Stands and Item Frames Invisibility
Quoted from the datapack page
Throw an invisibility potion on an armor stand or item frame to make it invisible
Use a splash water bottle to make it reappear!
Readable Clocks
Hold a clock to see the exact day and time it is in Minecraft in your action bar. Place it in an item frame and walk near it to achieve the same effect without having to hold the clock.
Party Cake
Quoted from the datapack page
Make your cakes more surprising by dropping a firework on them making them explode with confetti when eaten!
Server join/leave sound
Plays a sound whenever someone joins or leaves the server
