Changes:

Is now designed for 1.21.9 and 1.21.10! (Ported from Version 21g1.)
Added 8 new heads for the Copper Golem!
- These heads are more Pumpkin than they are Copper, so they won't act like Copper Blocks.
- They're also not complete Pumpkin, so you can't use them to resurrect the Copper Golem.
Added new sounds for the Copper Golem heads!
Charged Creeper head source improvements:
- Turning off Charged Creeper head drop case now works on mobs that drop vanilla heads!
- Noisy variants of Vanilla Heads can now be obtained under the Charged Creeper source!
- Charged Creepers now drop Charged Creeper Head if killed by a Charged Creeper!
- I would've done these before, if Charged Creeper drops weren't hardcoded back then.
Changed background and icon to match current game drop's theme.

Head Texture credits:

I'd experimented with making the Copper Golem Heads act more like Copper¹, but I found that what the change ultimately did is that it asks more processing power from the game in order to make what would otherwise be 8 distinctive heads feel like they're just 1 head.
So to preserve the heads' collectible value, these heads will be the sole exception when it comes to Copper stuff.
- Think of the heads as being more Pumpkin than Copper - I mean, you made them with a Pumpkin, there still has to be some of it in them somewhere, right?

1: Oxidizing normally, can be waxed and scraped.

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 Decapitation!
