Stackable
Stackable is a mod that increases all block stacking limits to any value less than 127 for Minecraft 1.20.4-1.19.2 and 2.147B for versions after 1.20.6
Quick answer
Which Stackable release should I use?
Stackable 2.1.1 targets 26.2 with Forge. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is Stackable required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Stackable 2.1.1 need?
2.1.1. Change the file and its required mods may change too.
Install Fabric API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it

What does Stackable add?
Stackable
Stackable is a mod that increases all block stacking limits to any value less than 127 for Minecraft 1.19.2-1.20.4 and 2.147B in 1.20.6+.
Why 127?
Effectively, I'm lazy, but in reality, Minecraft stores all items with a single signed byte which for our purposes only can be between -128 to 127, since negative values are invalid that leaves a maximum stack size of 127. Moreover, this mod is intended to be compatible with other mods which may also use signed bytes to store items.
Why make this mod
I don't know, other mods already exist that allow for stack sizes above 127. This was more for experimentation with creating mixins and understanding Minecrafts code a little better.
Will you update to X?
Maybe.
Will you backport to X?
Eh, not really.
There's a bug here?
I might fix bugs that are Vanilla specific, but mod compatibility is gonna be kinda hard to do
Mod support?
This mod should be compatible with most other mods, I've tested this mod in all of Fabric Orion, and it generally works, some blocks will limit their storage size to 64 but shouldn't crash. Most of my mixins to the code surround editing the interface that all inventory mods should implement to begin with, so if they call the stack size from that interface they should receive the appropriate value.
