Is a 1.20.4+ update in the radar?

I want one too

Forgot to update this issue, @DerpDerpling kindly did at my request a fork of this mod to 1.20.4:

https://github.com/DerpDerpling/ConnectibleChains/tree/1.20.4

I tested and seems to not trigger any errors. I think a release would be done!

I did have to remove some stuff from that port, so it may be a bit buggy

I am looking into updating it but I am the network changes made by the fabric api make it difficult.

From the blog to 1.20.2 (https://fabricmc.net/2023/09/12/1202.html)

There is one breaking change to Networking API: ClientPlayNetworking#createC2SPacket now returns Packet instead of Packet (and similar changes with createS2CPacket as well.)

I looked at the source code from @DerpDerpling to see what their attempt at fixing this was.
But I do not understand how they have done it, renaming the createSpawnPacket() function in the entity seems weird.
As that function is normally called when a new entity is created.

It seems the networking has changed a lot and I need to do a lot of work replacing it.

I have implemented some of the new networking changes and it seems to work.
I will do some more testing when I have time, hopefully this weekend.
If all works, then I will release the update.
When 1.21 is released I hope that time the wait isn't that long.
