0.92 is out, with Spartans, greatly developed facility interdependencies, tons of new stuff and improvements, and a few requests granted. Enjoy.
The next step: quite possibly Sectoids, as they're important to the story. Then a major overhaul of pirate paperdolls (Extended allows for 128 variations of gals - so far we only have 8!). I'm also tempted to work on terrain, or maybe new Passengers... Something along these lines.
If your request wasn't explicitly denied, be patient. I have pulled Zharkov's Batman (any ideas on new guys, or female versions?), as for Roxis231's alternate sprites, no upgrade this time, I want to do this in one go (ideally when the major work on extra paperdolls is finished).
No upgrade to the latest Nightly/Extended either, as I haven't touched upon what they have to offer, and all the tests suggest everything is working fine. I will upgrade only when it becomes unwise not to. As for Hobbes' terrain, it takes me a lot of work to upgrade, so I will do so only when he reaches a major milestone (lots of new maps & fixes)
