Version 0.90, titled ''Beta ThenThan Ever,'' was released on December 15, 2014.<ref>{{Cite web|url=http://www.pcgamer.com/kerbal-space-program-beta-update-released/|title=Kerbal Space Program beta update released|website=pcgamer|access-date=April 29, 2016}}</ref> This was the first (and only) beta update to ''Kerbal Space Program''. The update featured a full rewrite of the entire editor code, and now allowed for the ability to offset parts, sometimes into empty space. The update made several other improvements to the editor, such as the ability to sort parts by company, module, and mass, as well as the ability to assign parts to custom categories. The update also updated the style of the "Mk3" plane components, which were changed to be similar to the [[Space Shuttle]].
This version also implemented upgradeable buildings in Career Mode. When the player starts, they only have basic facilities allowing for small rockets with low mass and part count. The player can upgrade each of the facilities to increase mass and size limits, or unlock various other capabilities; for instance, a non-upgraded tracking station does not allow for placing maneuver nodes or for trajectory prediction using patched conics.
