What everyone's been waiting for

I can suggest you to take a look on this mod if it can help you with end biomes. ;)

I just wondered if this feature will ever come one day, it seems to have been abandoned.

They're adding a few minor end biomes in vanilla 1.13 (They're basically just variations in terrain, with no additional features), so we're just going to wait for that so we don't have to rewrite even more stuff, and of course, so it'll be easier.

Hm ok I understand. Then you will have to wait a long time, 1.13 will take so much time before to be released, Minecraft is almost totally rewritten, Forge will take surely a long time to be rewritten too. I don't expect to see Forge 1.13 before the summer end.

@Hypsellis Welcome to the future, 1.14 is coming yet Forge 1.13 is still not ready. IT is not dead , just a long way to go.

And still most modders thought 1.13 was persuaded forge would be ready before the end of the year. And here we are, forge is still not released, and not close to be. It still remains so much to do. Forge devs themselves assure that forge won't be ready before some monthes. Surely enough time for 1.14 to be released.

Any hope this will actually be coming? The end is still super bland, and the biome changes in vanilla arent even noticable

Not happening at this point. They're problematic, and I wasn't happy with any of the concepts I came up with and tested.

That's quite a sad end :(
