PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues.
Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong.
This is now resolved.
Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me.
Please as always, backup your worlds and test before updating to 1.16.2!
If you update to 1.16.2, there is no going back to an older build than this.

This fixes a bug with obfuscation helpers for attack cooldown
But every other change should stay the same.
Cleaning up a lot of helpers that pointed to already unobfuscated items.
Also adds final to many of the obfhelpers to assist with inlining.
This is pretty much a patch maintenance
Rewrites the Threaded task logic to no longer use 2 queues and instead
keep a single prioritized queue and do all of a chunks light tasks in a single batch
Fix a math issue in one place (Thankfully didn't seem to really be a common place since didn't notice anything)
Massive update to light to improve performance and chunk loading/generation.
1) Massive bit packing/unpacking optimizations and inlining.
A lot of performance has to do with constant packing and unpacking of bits.
We now inline a most bit operations, and re-use base x/y/z bits in many places.
This helps with cpu level processing to just do all the math at once instead
of having to jump in and out of function calls.
This much logic also is likely over the JVM Inline limit for JIT too.
2) Applied a few of JellySquid's Phosphor mod optimizations such as
- ensuring we don't notify neighbor chunks when neighbor chunk doesn't need to be notified
- reduce hasLight checks in initializing light, and prob some more, they are tagged JellySquid where phosphor influence was used.
3) Optimize hot path accesses to getting updating chunk to have less branching
4) Optimize getBlock accesses to have less branching, and less unpacking
5) Have a separate urgent bucket for chunk light tasks. These tasks will always cut in line over non blocking light tasks.
6) Retain chunk priority while light tasks are enqueued. So if a task comes in at high priority but the queue is full
of tasks already at a lower priority, before the task was simply added to the end. Now it can cut in line to the front.
this applies for both urgent and non urgent tasks.
7) Buffer non urgent tasks even if queueUpdate is called multiple times to improve efficiency.
8) Fix NPE risk that crashes server in getting nibble data
