Minecraft wiki entry for Development_versions, associated text: Improved terrain building speed when flying with Elytra. (MCPE-85614).
Fixed a bug that would crash the game when using the crafting table on Creative mode.
Fixed an issue with a runaway block ticking queue that occurred on a looping data-driven block that changed itself to a different permutation. The bug could cause memory issues, increase load and save times, as well as stalling the game periodically.
