* Career Mode: - Career Mode is now open! Although still very much under development, you can now start new Career saves. - Sandbox mode, of course, is also available from the start. * Research and Development: - Added the Research & Development Facility to the Space Center. - R&D allows players to unlock parts (and later other stuff) by researching nodes on the Tech Tree (In Career Mode). * Science: - Researching requires Science, which must be earned by performing experiments during your missions. - You can now collect surface samples while on EVA, and process them to do Science. - Science experiments return results, which are different for each situation in which the experiment is performed. - Experiments can (as all proper experiments must) be repeated over many different situations across the whole Solar System. - Added a new dialog to show the results of experiments when reviewing the collected data. - Added a new dialog to show a breakdown of all scientific progress made after recovering a mission. * Parts: - Added new scientific parts, like the Materials Bay and the Mystery Goo™ Canister. Also added experiments to many existing parts. - The old science sensors now have a purpose. They all have their own experiments which enable them to log scientific data. - The antennas are now functional, and can be used to transmit science data back to Kerbin, if recovering the physical experiments is not an option. - Antennas consume massive amounts of power when transmitting. Make sure you have fresh batteries in. - Added a new deployable antenna, which is an intermediate model compared to the two original ones. - Completely remodelled the Communotron 88-88 Comms Dish. The new mesh uses the same placement rules so it won't break ships that have it. - Nose Cones now actually help with improving stability during atmospheric flight. - Revised a lot of part values and descriptions, in preparation for them actually meaning something in the near future. - Overhauled the landing legs and gears, they now have proper shock-absorbing suspensions. * Editor: - Added a system to allow saving and loading of Sub-Assemblies. - Subassemblies are subsets of spacecraft, which can later be attached to other designs and re-used. * Space Center: - The KSC Facilities have all been revised, and feature new ground meshes and many other graphical improvements. - Greatly improved the Island Airfield. - Added lighting FX to several facilities. The Runway (among many other things) is now properly lit at night. - Added a new backdrop and soundtrack for the Astronaut Complex Facility. - Added a new music track for the R&D Facility. * Flight: - It is now possible to recover a flight after landing/splashdown on Kerbin without going through the Tracking Station. Look above the Altimeter. - The SAS system was again largely overhauled, based on all the feedback we've gotten from everyone. It's now stabler than ever. * Solar System: - Celestial Bodies now support Biome Maps, which are used to create different conditions for experiments. - Biomes are currently implemented on Kerbin and on the Mun, more will be added on later updates. * Launcher: - We've got a new launcher application for KSP, featuring a news bulletin, patcher management, and also allows you to tweak settings from outside the game.

==================================== v0.21.1 Bug Fixes and Tweaks: * Removed some unused assets from KSP/Parts. * Fixed an issue with some scenery meshes that could cause bits of the UI to become unresponsive in some cases (mainly in the VAB and SPH). * Tweaked some object scales slightly. * Tweaked the ocean color at sea level on Kerbin (was way too dark). * Fixed an issue that would cause lag while moving parts around the editor scenes if too many crews were hired at the same time. * Fixed an issue with the new SAS not properly maintaining attitude. Should be much better now. * Tweaked some parameters on the SAS to make it more responsive.
