Small tip for all who have trouble with forced updates, just copy the folder ...\Steam\SteamApps\common\Kerbal Space Program somewhere else, and start it from there. Even if there is an update you will still have your copy, and as there is no DRM you can still use it. Also use a copy to try out instable modcombinations, if it does not work just delete the copy and try again.
Nexts steps are to add more Boosters, and then mod it till it breaks.
The only bad thing about this update is that they still didn't readd the ability to shut down wheels by action groups, and the extendable radiators are still off center.
