In general, the client now has an acknowledgment system that will cause block changes made by the client to be reverted correctly.
Essentially:
The client enters a "prediction" stage, where any block changes made will have its old blockstate captured (this is referred to as "server state").
If you update blocks during this stage, the client will update this captured server state as long as they're still currently predicting.
After prediction is done (via an ack packet) all captured blockstates are reverted to their captured server state.
This means that if the server actually updated a block and send a block update packet, it's correctly set, while if a block wasn't updated on the server but WAS updated on the client (server state wasn't updated), that change will be reverted.
It should be noted that this system does not yet support block entities, so those still need to be resynced when needed.
I discovered this when noticing that blocks broken outside of the player's valid interaction distance are still properly reverted, even though the server doesn't send any block updates, only an ack packet.

For each player on each tick, enter block triggers are invoked, and these create loot contexts that are promptly thrown away since the trigger doesn't pass the predicate
To avoid this, we now lazily create the LootContext if the criterion passes the predicate AND if any of the listener triggers require a loot context instance

The existing EntityPickupItemEvent fixes patch moves the call to LivingEntity#onItemPickup for piglins after the respective EntityPickupItemEvent calls, which is correct.
However the patch moved the call so far down the line that the existing logic already mutated the picked up item entity, leading to faulty state being passed to the onItemPickup method.
To prevent logic in LivingEntity#onItemPickup to read from an ItemEntity that was already mutated, this commit moves the calls prior to the two respective mutations (either gold_nugget or rest).
This was chosen above taking a copy of the original item and restoring state later on to avoid a full item stack clone.
Upstream did not account for different hands when storing
the breed item for later use in the event. Also they only
stored a reference to the stack, not a copy so if the stack
changed after love mode was started, the breed item in the event
also changed. Also in several places, the breed item was stored after
it was decreased by one to consume the item.

Cost is a property of individual enchantments, and is used by vanilla in combination with environmental aspects like tool enchantability and bookshelf count to determine the final cost of an enchantment as shown in an enchanting table.
Having access to the base cost of an enchantment using these vanilla methods can allow plugin developers to determine the "value" of an enchantment, and use it in custom logic where needed. I came across this recently when trying to assign an economic value to enchantments during tool repairing, and noticed these values don't seem to be obtainable under the current API.

When ChunkAccess was converted to an abstract class some versions
ago, the code to initialise nibble arrays should have been moved.
However, the code was not moved and so now mods constructing their
own implementations of ChunkAccess would not have the nibble arrays
initialised.
This is ported to Paper from Starlight to keep the code base in sync,
not because it fixes anything known.
During feature generation, light data is not initialised and
will always return 15 in Starlight. Vanilla can possibly return
0 if partially initialised, which allows some mushroom blocks to
generate.
In general, the brightness value from the light engine should not
be used until the chunk is ready. To emulate Vanilla behavior better,
we return 0 as the brightness during world gen unless the target
chunk is finished lighting.
The regular light retrieval outside of WorldGenRegion remains
the same, as behaviorally chunks not lit should be at max
skylight and zero block light.
There is no point in initialising the sources in Starlight,
as we do not use them. Additionally, they are not saved to
disk so we do not need them.
Maintaining and initialising them is not a negligible cost,
which is why they are being removed.

Since the method is overloaded, the call to super (which is changed
to call the overloaded method) without the additional parameters
will result in recursion.
The correct logic to implement NOT_SAME with Shapes#block()
is to test whether any shape data exists outside of [0.0, 1.0]
and to test whether the shape is completely filled from 0.0 to 1.0
on all axis. This can be implemented by checking whether the
bounds represent the full block and whether everything within
the bounds is filled.

Instead of searching/testing every player online on the server,
we can instead use the nearby player tracking system to reduce
the number of tests per search.
The CHUNKY_FIXERS field is modified during the constructors
of the BlockFixers, but the code that uses CHUNKY_FIXERS does
not properly ensure that BlockFixers has been initialised before
using it, leading to a possible race condition where instances of
BlockFixers are accessed before they have initialised correctly.
We can force the class to initialise fully before accessing the
field by calling any method on the class, and for convenience
we use values().
When per-player mob spawning is enabled we do not need to randomly
shuffle the chunk list. Additionally, we can use the NearbyPlayers
class to quickly retrieve nearby players instead of possible
searching all players on the server.
