0.21

Version 0.21 was released on 24^th October 2014.

New

The Space Center scene now uses the same terrain as in flight.
Time now passes in the Space Center scene, and day/night is consistent with in-flight.
The game terrain persists across scene transitions, making loading scenes much faster.

Completely overhauled the interior models for the VAB and SPH buildings, complete with animated trucks and cargo lifts.
All-new exterior models for the VAB, SPH and Tracking Station.
New Astronaut Complex building.
Added a description field where you can write up a few lines to describe your space-faring contraptions.

It is now possible to assign crew manually to missions before launch, both from the Construction Facilities and from Launch Sites.
Added completely new Launch Dialogs on the Runway and Launchpad at the Space center.
The new Astronaut Complex dialog allows you to hire crews from a list of Applicants, and view the status of all your crewmembers.
Revised the crew handling game logic, for a much more reliable and robust system.

Rewrote the SAS control logic from the ground up.
SAS is now enabled for the entire vessel, and requires actuators like winglets, RCS or others to actually have an effect.
Repurposed the old SAS modules are now Reaction Wheel Modules, that apply torque while consuming electricity.
The new SAS logic allows applying manual input while SAS is on, letting you set the ship's attitude without having to constantly toggle it.

Added a new module to generate craters procedurally on the Mun.
Largely revised Kerbin's terrain to produce much more interesting mountains, hills, valleys and coastlines.

Removed the physically-impossible "End Flight" button.
Added new options to "Revert" a mission back to launch or to construction.
Added new 'Recover' button on the Tracking Station, to allow recovering a vessel (as opposed to Terminating it) when possible.
Recovering vessels makes its crew available again, while Terminating kills them.
The 'Space Center' button now allows you to leave flight at any time, warning when necessary about saving restrictions.

The game now tracks your progress as you play, providing essential data for the upcoming Career Mode features.
Progress data is (optionally) uploaded to our servers,

Scenario Modules now properly save and load when the rest of the game saves and loads.
Scenario Modules can now have multiple target scenes set.
Improved the internal logic for switching to nearby vessels, it shouldn't refuse to switch with valid vessels nearby anymore.
Added a system to attempt upgrading incompatible save files if/when possible.
Tweaked PQS on other planets and moons to not initialize until approached. Improved performance a bit.
Added a new system on PQS to clamp terrain subdivision while moving very fast. Orbiting low near the surface is a lot smoother now.
Many more small tweaks and improvements.
