 - Players no longer get pullbacks when sprinting on slabs, stairs and various other blocks when `player.anti-cheat.allow-movement-cheats` is set to `false`. (This bug has been around for over 5 years, so many of you will be used to its existence.)
 - Fixed entity collision box calculation not taking clip distance into account.
 - Entities now step up the correct height of the target block, instead of jumping into the air 0.6 blocks and falling back down.

+# 3.15.2
+- Fixed issues with preloading `SubChunk`.
+- `/gc` and automatic garbage collection will now release unused heap blocks back to the OS. Previously, the PHP process might hold onto these blocks indefinitely even when not used, causing elevated real memory usage.
+- Added some documentation to `FurnaceBurnEvent`.
