Some details on Kerbal Experience and Facility upgrades have emerged.
Ulminati you're going to love some of these.
First thing, probe cores will now have "levels", that is the more expensive and hi-tech cores integrate some, but not all, types of SAS lock-on that pilot kerbals can gain with exp. Stayputniks gonna have crappy SAS with basic functionality, Hex cores good ones.
Engineers repack parachutes, repairs landing legs and wheels. It was mentioned that in the future they will do more (Drilling for fuel when mining gets added? Placing parts in flight?), but those features are secret for now.
Scientists are pretty dull, increase science output, though hopefully the traits are specialized like "reduced transmission data loss" or "more science from atmo experiments".
KSC upgrades however look quite fun. You need to upgrade mission control to receive more contracts and to unlock maneuver nodes (first upgrade unlocks those). Without tracking station upgrades you have neither patched conics or orbital lines(!!). VAB/SPH levels limit max number of parts while launchpad/runway limit max tonnage of the craft, of course max level takes off part/mass limitations.
Research facility has a cap on maximum amount of science you can spend to unlock a node (basically you can't unlock nodes that cost more than X science until you upgrade).
Astronaut Complex limits your max kerbonauts and allows you to train them.
Supposedly difficulty options can make some stuff, like maneuver nodes, appear with higher upgrades (or may be disabled for good).
Pretty solid features, definitely a reason to fire up Career mode once again.
Fine Print mod guy talked about how he changed rover and aerial survey contracts for the mod's integration into the stock game in 0.90.
Basically now there is a single survey contract type. Waypoints may still require being on the ground or flying around but how you get there is up to you. That is you do not need a rover or plane, you can use an ion engine hoverbike if you wish (which reminds me that I need to build one some day). But they now require you to do specific experiments at points, which I think is pretty good. The above waypoints are color-coded to indicate which belong to which contract.
