I sure love a glass cockpit. Haven't I seen those LCD displays before?

Fuck, it is a mod, my bad. Retarded morning posting.
But here, this is definitely in 0.23:
RAPIER (the KSP SABRE ripoff), you can set it to autotoggle so that it switches to rocket mode when your intake air runs too low to work in jet mode. The thrust limiter value is a tweakable on engines in the VAB. You can for example do a T shaped rocket with it that flies stable by limiting the thrust on the third odd engine enough to shift the center of thrust towards the center of mass. So launching something like the space shuttle is easier now.
Landing gear tweakables in VAB/SPH. Landing gear can now steer like rover wheels making taxing better. You can tweak other stuff as well like engine gimbal range, landing legs default deployment state etc.
Science archive screen in the R&D building, it will be in the game sans the ugly mustache streamer of course. Lets you track the experiments you did and the science you got.
Also minmus is getting biomes, not sure about other planets/moons. It would be a bit silly if just Minmus is getting them now. They should at least try to fit Duna and Ike biomes into the next update as well.
EDIT: Some more news on the focus of development after 0.23.
They want to make the game "scope-complete" in 2014. So basically add every necessary remaining feature at least at a basic level. Resource mining will probably not happen at all at least before any kind of expansion, lead dev said the system was too much of endgame content requiring mastery of the game, making the game top-heavy and thus "unfun". Major
However they changed their mind on multiplayer, kept it secret for some time, they would have kept the plans for it a secret longer as one mod already did it. Both for career mode and sandbox mode, after they finish the latter. It will work around timewarp by syncing timelines, possibly allowing you to share vessels and having your bros control other kerbals, have them EVA, drive rovers and do shit while you keep control of the ship. Would still prefer resource mining though.
Contracts for missions, cash, costs and reputation are coming in 0.24. Kerbonauts are supposed to get experience for missions in one of the future updates(tm) allowing them to level up skills.
Repairing your ships out in deep space is supposed to be possible in the future somehow.
Missions will be randomly generated based on your progress as tracked by the progress tracker they added in 0.21. Missions will have deadlines and it will be possible to fail them and pay fines. As an incentive to take them most of them will give cash up front.
If you run out of cash to pay for launches you will be able to trade prestige/reputation or science for it.
