PermaEfe Extreme Survival

For the PermaEfe datapack, the 1.21.9 update changes the pack format to 88 and introduces minor version backward compatibility, eliminating the need to constantly update your pack.mcmeta file. Your custom dimension generation now strictly requires the preliminary_surface_level field in the_dark.json, removing older variables. Recipe validation is also much stricter, meaning files like your tablillaop.json will completely fail if any pattern letter is left undefined. Additionally, setting an Enderman's AngryAt tag to 0 will now flood your console with errors, requiring you to use data modify to inject your actual UUID instead. Finally, if you use the flash particle in any of your functions, the command will now crash unless a mandatory color parameter is included.

The 1.21.10 update brings absolutely no technical changes for PermaEfe. The pack format remains 88, and your datapack will function natively without modifying a single line of code. This release is strictly a Mojang hotfix designed to patch vanilla game engine bugs related to pistons, teleportation rendering, and water physics.
