So now to the actual news:
IC2 builds for 1.8.9 are now available. It is available at the usual place.
No, it does NOT contain IC2 machines that are compatible with RF,
No, it still contains liquid UUMatter and
No, it is still called IC2.
It still contains bugs, but it should be mostly working.
Create backups of your world, when you're using it. (And I don't say that, because I made a mod, that will help you with exactly said thing)
Again, we're sorry for any inconvenience caused.
Thanks for everyone who helped - AlexIIL, asie, Chocohead, Direwolf20, estebes, Player and SpwnX
