So. We've got some news.
Gregtech 6 is going to come out within a week, with it coming enormous API changes, and a total rewrite of the metaItem system. Greg was unhappy with the GT5 system he had in place, and decided it was best to simply scrap all that and start afresh. However, despite coming out within the week, it will be nowhere near full-featured. In fact, it will pretty much only contain metaBlocks and world gen. Because of this, and the fact that upgrading from GT5 to GT6 will require a total world reset, we had to make some tough decisions.
Learn Gregtech [Cub]
Cub will be shelved until GT6 is stable. Sorry. The modlist will stay mostly the same, but we will take this as an opportunity to rethink the map and the quest progression so that then GT6 is stable we can pump out a mappack as quick as possible.
Cat
Information on Cat will come in a bit. Just know that if we end up releasing this version, in the coming weeks/months until GT6 is ready, any progress you make will be reset after the update to GT6. However, if GT6 does indeed take a while, you should have plenty of time to play around with the final build of GT5.
Other packs
We may be able to take this time to work on other packs, possibly the Buildcraft pack. If you are interested in this, please comment below.
