Subject: [PATCH] Cache DataFixerUpper Rewrite Rules on demand
Mojang precaches every single potential rewrite rule that could ever
exist on server startup. This includes rules from all the way back to versions from 6+ years ago.
This is the source of why the server hogs every CPU core at 100% every start.
For anyone who hard resets for updates or has force upgraded their entire world, this
results in completely wasted cpu cycles.
This massive CPU usage also delays server startup time.
We improve this by making "min version to precache" that defaults to a future version
so that no rewrite rules are precached.
someone who expects to be converting a lot chunks could theoretically set
-DPaper.minPrecachedDatafixVersion=<dataVersionConvertingFrom> as a startup
parameter and only build from that point on.
However this will likely never be needed as the server will still run
the same cache logic on demand when it's actually needed. The only
cost would be some delay on the FIRST chunk conversion, but paper already
runs chunk conversions on another thread so this will likely never be
a concern for TPS.
This patch will significantly reduce CPU use on startup, reduce memory usage,
and improve server startup time.

Subject: [PATCH] Lazily track plugin scoreboards by default
On servers with plugins that constantly churn through scoreboards, there is a risk of
degraded GC performance due to the number of scoreboards held on by weak references.
Most plugins don't even need the (vanilla) functionality that requires all plugin
scoreboards to be tracked by the server. Instead, only track scoreboards when an
objective is added with a non-dummy criteria.
This is a breaking change, however the change is a much more sensible default. In case
this breaks your workflow you can always force all scoreboards to be tracked with
settings.track-plugin-scoreboards in paper.yml.

Subject: [PATCH] Fix bell block entity memory leak
BellBlockEntity has a list of entities (entitiesAtRing) that was not being cleared at the right time, causing leaks whenever a bell would be rung near a crowd of entities.

Subject: [PATCH] Avoid error bubbling up when item stack is empty in fishing
loot
This can realistically only happen if there's custom loot active on fishing
which can return 0 items. This would disconnect the player who's fishing.

Subject: [PATCH] Fix client lag on advancement loading
When new advancements are added via the UnsafeValues#loadAdvancement
API, it triggers a full datapack reload when this is not necessary. The
advancement is already loaded directly into the advancement registry,
and the point of saving the advancement to the Bukkit datapack seems to
be for persistence. By removing the call to reload datapacks when an
advancement is loaded, the client no longer completely freezes up when
adding a new advancement.
To ensure the client still receives the updated advancement data, we
manually reload the advancement data for all players, which
normally takes place as a part of the datapack reloading.

Subject: [PATCH] Add Wandering Trader spawn rate config options
Adds config options for modifying the spawn rates of Wandering Traders.
These values are all easy to understand and configure after a quick read of this
page on the Minecraft wiki: https://minecraft.wiki/wiki/Wandering_Trader#Spawning
Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
in IWorldServerData are removed as they were only used in certain places, with hardcoded
values used in other places.

Subject: [PATCH] Optimize Dynamic#get Missing Keys
get was calling toString() on every NBT object that was ever asked for an optional
key from the object to build a string for the error text.
When done on large NBT objects, this was using a ton of computation time building the
JSON representation of the NBT object.
Now we will just skip the value when 99.9999% of the time the text is never even printed.
