After a while of having to deal with landmines that came with Mounts of Mayhem, the Datapack Series are finally here for the last game drop of 2025!

Changes:

Is now designed for Minecraft 1.21.11!
Admin Books have been removed and replaced with the Admin Settings menu.
- The Admin Settings menu lets you tweak all settings in one go, and apply them all at once!
- Accessing this menu is the same as getting the Admin Book, so it should be easy to get used to it.
New Presets Menu:
- This lets you view and edit a Custom Preset's values before applying them!
- Triggers each time you load a Custom Preset.
New Show Configs Menu:
- This lets all players read Admin Setting values in detail!
- Access by running /trigger tdp.readconfigs.
- Players will be notified on how to access this menu each time the Settings were changed.
The player who made changes to packs' Admin Commands are no longer announced in-game.
- Mainly because that job is meant for the server consoles, and that information doesn't help with the players' gameplay experience anyway.
IHF files now have their descriptions updated to reflect the recent set of changes.
Updated advancement background to match game update's theme.

Update notes:

Because the underlying system has to be reworked to support Admin Settings, your settings will be reset when you update to this version.
Don't worry though, you can bring your settings back instantly by loading a preset saved in the previous version, so be sure to do that before updating!

If you're wondering why I'm dropping the Admin Books now: Mojang secretly obliterated a hidden mechanic that I used to make Admin Books feel nice to use, this was on top of the forced confirmation screen they added in 1.21.6.
- Even if it's a bug that'll eventually be fixed, the damage has already been done, and I had to deal with it if I want to properly update all my packs to this release.
- The reality is, adding new tools to make stuff with proper care just takes this long, and I have to make sure that the tool I'd built won't cause pack clashes when it's used on my other packs that were also running on Book Binder.

Here's the real secret: I've been doing all this since 2018, but ad revenue alone is tiny compared to the time it took to research, develop, test, and maintain all this for free.
- As a result, most of my days are swallowed by other work just to keep the lights on.
- With your help though, I'll be able to go full-time: Faster updates, better tools, and many more features.
  Together, we don’t just keep this going, we build it into what it was always meant to be.
- So help me keep the lights on here, and have fun with BlockSeat!
