Release notes:
http://arcengames.com/mediawiki/index.php?title=The_Last_Federation_Alpha_Release_Notes#Alpha_Version_.906Restart steam to force a quicker update if you like.
This is the first one to go out both as a steam release and as an independent-updater release. So if you haven't restarted steam yet, you can actually download it through the game itself; I gave it a shot and it worked just peachy.
That said, please do use Steam's servers when you can -- saves us a lot on bandwidth.
So what is new here?
1. Wowee was I able to get some impressive savings on RAM usage in there. 56%, to be precise -- or 1.5 GB of RAM usage savings when we're talking about all the textures being loaded at once (which is rare, but still).
2. We've split "Normal" difficulty into upper and lower normal halves. The default is lower, and that's what normal previous was. The new upper normal is halfway between that and Hard, more or less, and I think is appropriately named because it really is a good baseline version, but just for people on the more upper end of the spectrum. IE, experienced gamers could easily just start with upper normal and be perfectly happy.
3. Also, I've done some dial-tuning and some technology-blocking to really bring out the already-pre-existing uniqueness in the races. Some of the multipliers that were in there for things like technical prowess were too low to make a really practical difference, and so you wound up with everybody getting more same-y by the end of the game. Interestingly, this should actually help to make the outcomes of games even more varied, since the asymmetry is higher.
Enjoy!
