- Lighting is no longer guaranteed to be available on every chunk. It's now calculated on the fly as-needed.
- `/op`, `/deop`, `/whitelist add` and `/whitelist remove` no longer cause player data to be loaded from disk for no reason.
- Timings now use high-resolution timers provided by `hrtime()` to collect more accurate performance metrics.
- Z-order curves (morton codes) are now used for block and chunk coordinate hashes. This substantially improves performance in many areas by resolving a hashtable key hash collision performance issue. Affected areas include explosions, light calculation, and more.
- [`libdeflate`](https://github.com/ebiggers/libdeflate) is now (optionally) used for outbound Minecraft packet compression. It's more than twice as fast as zlib in most cases, providing significant performance boosts to packet broadcasts and overall network performance.
### Logger revamp
- Many components now have a dedicated logger which automatically adds [prefixes] to their messages.
