I'm curious; will TiC, when added, get custom materials done with datapacks? Because I'm not sure that functionality is completely implemented, as I don't see any way of making new molten substances in the wiki. Does that have to be done with an actual mod?

We haven't discussed that atm :)

It's now possible thanks to the wonders of KubeJS: #2294

I might be missing it but I just see 1.12 versions in the downloads?

Look closer friend

Heres also some more proof that its not an april fools joke

Sneaky all files....
I swear.

Exciting news!

I'll have a look tomorrow if the file is still there :P

Bit unfortunate that they skipped the documentation. Seems like enough has changed that even cursory documentation would be very helpful.

That's not even in >.<

This is just a small error on their side. The mod just got released and it still has a way to go so better leave it like this for now.

Yeah, I'd vote for waiting, personally.

I don't think it should be added until phase two at least. A lot more content is being added, including some minor worldgen changes, and the documentation should be finished by then.

Temporary documentation is here.
And the roadmap for planned changes is here.

Is there any futher information on this?

It's being evaluated. It's still in alpha, so probably a little early for inclusion, but that will probably depend on how stable and functional an alpha it is.

We're gonna wait a bit :)
