Xenonauts has a new development update on the games official forums.
More information.As V19 Stable has just been released, this development update is mostly concerned about what's been going on in the background recently and what we have planned for the immediate future. I think the first thing to do is to remind everyone of the huge amount of progress that has been made over the last three months since V18 Stable - there's been massive improvements to almost every aspect of the game (balance and AI most obvious amongst them), and it's easy to forget quite how much has been done.
The V20 series of builds is intended to be mostly polish, with an emphasis on getting the new UI installed / fully functional. The rest of the game will see more tweaks, but it's not likely to change quite as much as it did from V18 to V19. There will be further balance work, further AI improvement, new maps, reworking of the way jetpacks work and probably the Geoscape UFO intelligence too.
