Starsector 0.97a is out! (02/02/24); New blog post: Simulator Enhancements (03/13/24)
Well, IBB was just one of many things. I'm actually *nearly* to the point where I could release without IBB support. It has legitimately taken this long to get everything up to full 0.9 quality.
Like Bastion above, I'm not bothered if the IBBs were to be excluded in a first 0.9 compatible release. I mean, the IBBs are nice, but I use SWP primarily for the great variety (and quality!) of ships and weapons that it provides.
