  • Removed the Splash Screen scene. Now the game starts loading as soon as the application starts.
  • Rewrote and organized many scattered game events into a single coherent GameEvents System, which plugins can use.
  • If you crash/explode, focus now shifts to the nearest controllable vessel (if any) instead of going straight to the End Flight dialog.
  • Many more small bug fixes and tweaks.
  • Decoupled vessels now properly inherit the action group state of the original vessel.
  • "Root-dropping" decoupling now properly preserves the staging count for the new decoupled vessel.

v0.18.0

Released 1st December, 2012

New

  • Docking: Connecting vessels together is now possible! Build space stations, surface bases, or assemble huge spacecraft in orbit.
  • Flight Planning: Getting to other planets and moons just got a lot simpler. Place maneuvers along your orbit to create a flight plan, and then just follow the guidance cues. No need to figure out angles or hold a protractor to the screen!
  • Improved Map UI: New map icons show close approaches, intersections with other orbits, and a lot more, so you can focus on getting where you want to go, instead of worrying about how to get there.
  • New Vessel Types and Vessel Renaming: Building a station? You can now rename and set your vessel as one of several new types, so it'll show on the map with the appropriate icon and name.
  • Automatic Fairings: Rockets now look like proper rockets! Several parts now have automatic fairings that pop up whenever something is stacked below them, and then jettison away during flight.
  • Much Improved Models and Textures: Many of the old parts have been completely redone, with carefully constructed meshes and hand painted textures, to give KSP a new look.
  • A slew of new part types: solar panels, docking ports, batteries, trusses, ion engines, electric lights, side-mounted parachutes (or "radial parachutes"), crew cabins, new science parts, and a heap more!
  • Unmanned Probes: New unmanned pods for building probes and unmanned missions, plus a huge amount of new probe parts.
  • Action Groups: A new way to control your ships! Instead of having everything done through staging, you can assign parts to groups that are controlled with a keypress. Set up Abort systems, or rig up complex contraptions. Or just let the game handle it automatically.
  • New Input Modes: No need to have two hands on the keyboard and a third one on the mouse anymore. New input modes make for much more ergonomic controls, and it's all remappable!
  • Two new celestial bodies: New places to explore, with interesting and varied terrain.
  • New Resources System: Watching fuel drain has never been so much fun! New resources allow for completely new possibilities. Energy, Fuel, Oxidizer and other resources now flow through your ship. Manage them as you fly, and pump them across parts.
  • Electricity: More power to the Kerbals! Many new functional electrical parts added, like Solar Panels, Batteries, and even a Nuclear Reactor!
  • Lights: Landing on the nightside just got a lot less deadly, with new landing and floodlight parts.
  • Functional Air Intakes: Turbines now properly require air to run, and Intakes can provide it for them, as long as there is an atmosphere around you.
  • Music: KSP now has its own soundtrack, featuring many cool tracks, from smooth jazzy tunes to build ships by, to wondrous spacy themes as you explore the solar system.
  • Much improved planets: Kerbin looks a lot better now, with hand-built terrain features. Moho and Eve also got major overhauls, and many others have also been improved.
  • Performance Tweaks: New terrain optimizations and a system to prevent lag by slowing the simulation make for a significant improvement in performance.

v0.16

Released 20th July, 2012

New

  • Kerbal crewmembers in Extra-Vehicular Activities, both at the surface and in orbit.
  • Kerbal scientists, mechanics and ground crew all around the Space Center Facilities.
  • New Internal Cockpit models, with full modding support.
  • New (Much lighter on performance) Particle Effects and Explosions
  • Several new, larger rocket parts.
  • Added a Launch Clamp part. It holds the ship in place at the pad so it doesn't crumble to pieces before you get a chance to launch.

Bug Fixes and Tweaks

  • Set all parts on the same vessel to ignore collisions with each other. Hopefully this will solve all part-to-part collision problems.
  • Reduced the minimum collider intersection threshold to much less than before. Should increase collision accuracy and hopefully solve issues like landing gear going through the ground. (all thanks to above fix)
  • [API Change] MemoryStream wrappers that were mistakenly not committed for 1.15.1 have been added to the code.
  • Packing/Unpacking ships is now done without affecting the ship's scene hierarchy. Now, vessels take care of keeping their own parts in place while packed, making for much more stable physics behavior when going in and out of time warp.
  • Improved vessel/part loading from persistence procedure, for more stable and accurate flight resuming.
  • Fixed a bug in the Tracking Station scene, which prevented scrolling the vessel list.
  • The Vessel Switching keys now only cycle between nearby vessels and won't cause the scene to reload anymore. To switch to far-away vessels, you must use the map view.
  • Added key and axis bindings for EVA controls. Reorganized the Input Settings screen a little.
  • Added separate control bindings for walking and jetpacking on EVAs.
  • Added 1:1 EVA rotation axes. Using them disables the automatic orientation system.
  • Fixed RCS and SAS toggling on other vessels.
  • Vessels take collision impact momentum into account whenever possible
  • Fixed a problem where vessels would be stuck as 'Landed' if boarding a part while in contact with another.
  • Fixed issues with the large Landing Leg colliders.
  • Added patcher auto-updater. Will redownload the patcher if a better version is available.
  • Tweaked Physics settings to reduce landed part wobble.
  • It is now possible to close the Flight End screen without leaving the flight scene (to switch vessels).
  • Tweaked part collision handling for better efficiency.
  • Landing Legs now use a much improved collision handling system, eliminating leg wobble on heavy ships.
  • PartTools can now serialize WheelCollider components.
  • Improved detection/response to vessels below terrain and much better terrain altitude detection for vessels.
  • It is no longer possible to save the game (or switch vessels) while very close to the ground and not landed (could cause terrain fallthrough).
  • Fixed the crew capacity values on the part.cfg files.
  • Fixed the Orbit initialization routine, to prevent NaN errors on landed craft
  • Fixed parts that use the Part class having a "Part Type not available" message on their descriptions at the VAB.
  • mbm texture files are now DXT compressed and cleared from RAM as soon as they're uploaded to the GPU. RAM usage is massively improved.
  • Fixed some issues with the patched conic solver not finding proper SOI transitions sometimes.

v0.14.1

Bug Fixes

  • Found and fixed the real cause of the staging issues that have plagued every release from 13.2 onward.
  • The debug console is no longer spammed with NaN errors. This could cause extreme lag in densely populated game worlds.

  • Landed or Splashed vessels now display their coordinates (or location, if available) when moused over on the Map View.
  • More Crew Members so you can launch missions while others are underway.
  • An External Module Loader, which enables mod makers to program their own part modules.
  • Added small fuel tank and small engine parts
  • Added Landing Gear
  • Added a more efficient input lock for when vessels are in physics-hold mode, to prevent staging during that period.
  • Made the Landing Gear action a mappable key.

Bug Fixes

  • The flight camera is no longer able to go upside down.
  • The ORBITAL camera mode will no longer change orientations when switching spheres of influence.
  • Fixed an issue with .craft file saving and loading, which makes it possible to save ship titles independently of the file name.
  • Un-warping a landed ship will no longer cause an unphysical jerk on it, which could possibly destroy it.
  • Landed/Splashed vessels no longer show an Apoapsis icon on the Map View.
  • The Map Camera now responds to the keyboard bindings for camera zoom.
  • Decouplers now obey the second law of physics (Acceleration = Force/Mass)
  • Decouplers now obey the third law of physics (every action has an equal and opposite reaction).
  • RCS Fuel Tanks now drain symmetrically if placed using symmetry.

Bug Fixes

  • Fixed a bug with symmetry in the VAB.
  • Fixed an issue with the main camera that would create sporadic moments of lag in map view.
  • Fixed a bug that caused symmetrical parts to lose the reference to one of their counterparts, leading to incorrect symmetrical placements.

Note: 0.13.3 is an additional free version with bug fixes.

v0.13.2

Released 26th January 2012

Bug Fixes

  • Fixed a bug with symmetry in the VAB.
  • Fixed an issue with the main camera that would create sporadic moments of lag in map view.

v0.13.1

Released 11th January, 2012

New on 0.13.1

  • Recompiled on the latest version of the Unity engine, to add multithreaded rendering support and better memory management.
  • Changed the Fuel Line flow direction, so fuel will flow from the first-placed end of the line to the second end.
  • Holding Ctrl and clicking on a part on the ship at the VAB will now automatically flip the parts list to the selected part's page.
  • Added in-game credits.

Bug Fixes

  • Fixed the custom part sounds loading system, which wasn't working on the last release.
  • The part loader will no longer freeze if it cannot find a part module to load. It will load the base Part module, and make it visible but unavailable on the VAB.

  • Fixed an issue with the part loader, which would crash if a binary mesh was found, but no .dae or .obj file was present.

v0.13

Released 16th December, 2011

Optimizations

  • Removed a lot of needless halts on the part processing routine during loading.
  • Restructured the sound loading system so the main loading thread doesn't wait for it to finish before moving on.
  • Deferred adding of several part components so they're only added when they're needed.
  • Mesh tangents can now be loaded from file, instead of being recalculated every time.
  • The mesh loader now ignores materials from file, because they were going to be replaced anyway later.
  • Meshes are now saved to binary files (serialized) when loaded for the first time, and loaded from those files when they're available.
  • Changed the rendering method for the part icons on the staging sequence. This can prevent thousands of objects from being created when flying large ships.
  • Ship parts now have adjustable levels of physics, so small parts are not as deeply simulated as large ones. This reduces the amount of physics objects and joints to simulate.
  • Reduced the amount of code components attached to each part, making for less calls on each frame.
  • Tweaked the part heat exchange model, for a considerable fps boost with very large ships.

New on 0.13

  • The part loader will check if the saved optimized meshes are out-of-date, and update them when necessary.
  • A new Fuel Line part, that allows fuel to be drained off external (side-mounted) tanks.
  • It is now possible to warp time freely when the ship is landed.
  • Added a progress bar for the loading screen.
  • Pressing F2 will hide the UI completely (so you can take UI-free screenshots).
  • Added a new icon for the Fuel Line parts.
  • Changed the icon grouping rule on RCS Blocks and Strut Connectors to group to all parts of the same type on it's stage.

Bug Fixes

  • Fixed the mission timer not getting started if the first stage was moved before launching.
  • Liquid Fuel now flows from the top attachment node, instead of from the parent part (unless there is no top node, in which case it flows from the parent part).
  • Parts now keep the references to the part attached in each attachment node. (makes top-node based fuel flow possible)
  • Fixed a bug which prevented the ship selection dialogs from receiving double-click events. Now it is possible to select a ship file by double clicking on it.
  • Improved rendering of hyperbolic (escape) orbits in the map view. The trajectory is now a constant size regardless of eccentricity, and isn't warped by the splines.
  • The Map camera will now remember it's last position, and return to it when the map is reopened.
  • Fixed a problem that made it possible to delete the command pod in the VAB by using Ctrl+Z.
  • Increased the heat conductivity and heat dissipation values for all parts, to compensate for the new heat exchange system.
  • Exposed a 'thrustVector' cfg parameter for Liquid Engines. This allows you to set the 'default' thrust direction for an engine, same as with SRBs

v0.12

Released 11th November, 2011

New on 0.12

  • Re-added the Mun
  • New Orbital Camera Mode. Like Free Mode, but aligned to the solar system plane, like the Map View Camera is.

Bug Fixes

  • Improved the way velocities are applied when resuming physics.
  • Fixed the Advanced SAS icon showing as a question mark on the VAB.
  • Fixed a bug where cloning parts by removing and undoing would cause them to receive duplicate IDs (and crash the game when loading the ship again).
  • Tidied up the flight statistics numbers formatting a bit, so they're easier to make sense of.
  • Time Warp will now smoothly increase/decrease towards the set time rate, for a much more fluid transition.
  • Made several improvements to the Map View orbit rendering.
  • Fixed the rails to physics transition, so that there is no significant change anymore in orbital parameters when going out of warp.
  • Made some significant improvements to the physical joints that hold the ship together. Ships will not wobble anymore when going back into 1x time after warping, and the joints themselves are more stable overall.
  • Made a small tweak to the part tooltips on the VAB, to prevent them from going off-screen on small resolutions. (was noticeable with the new command pod selection dialog)

v0.11.1

  • New "Atmosphere" Gauge in the UI, indicates how deep the ship is in the planet's atmosphere.
  • The Orbit system can now track and propagate hyperbolic (escape) trajectories.
  • Parts can now cast shadows on themselves.

Bug Fixes

  • Added a simple but hopefully effective stall simulation for winglets and control surfaces.

  • The MET display will now start counting on liftoff instead of on flight start.
  • Tuned the terrain system a bit, to improve visual quality at high altitudes.
  • Greatly improved the input lock system. Now, components that lock game controls won't override locks placed by other components.
  • Improved the flight camera code. On Chase mode the camera will not spin around at the poles anymore, and both modes are more stable overall.
  • Optimized the terrain system rendering, and got a nice boost in performance during flight.

v0.10.1

  • Option to Simulate in Background in the settings.cfg file
  • Undo/Redo actions in the VAB, by Ctrl+Z and Ctrl+Y
  • Fuel tanks are now stackable to increase fuel amount (and weight )
  • On-screen text popup to let you know the current camera mode
  • Cfg interpreter can now parse 2D, 3D, and 4D Vectors, as well as rotations (in angle-axis format)
  • Cfg-defined thrust positions and orientations, make retro-rockets and any other craziness open for addon parts.
  • Parts may now create new stages for themselves through the cfg (used to be decouplers only)
  • New texture for the Solid Rocket Booster
  • The game now checks for updates against the KSP site, and let's you know if there is a new version available
  • Loading screen moved to before the main menu appears.

Bug fixes

  • Liquid Engine particle effects responding to engine cutoff
  • Icon indicators for all parts that need to show information
  • Custom icons for all part types
  • VAB placement bug with tricouplers and fuel tanks (and decouplers)
  • Reposition the Navball and main camera focus, so the ship isn't obscured by the interface - this one is kinda moot now, since the new camera centers the ship better, and the navball doesn't hide the ship anymore.
  • Pause also affecting particle effects
  • Pausing the game no longer produces a G-force peak
  • SRB mesh normals correction
  • Complete rewrite of the flight camera code. No more jitters and a number of new options in the settings.cfg
  • Relaunch button on pause menu. No need to end flight to relaunch.
  • Version text on main menu resetting after returning to it from game.
  • Inverted the middle mouse button zoom. Now mouseing forward brings the camera closer.
  • The text on the stage indicators no longer appears over other interface elements
  • Fixed excessive wobbliness with side-attached parts
  • Radial decouplers now have their own module (they used to share modules with the stack decoupler)
  • Increased the inclination range for the VAB camera from 45° to 80°
  • Updated tutorial to reflect the changes made in this update (like the new cameras in flight).
  • Tweaked the Radial Decoupler separation. It can now eject lit SRBs safely away from the ship and not kill the crew everytime.

v0.7.3

Released June 24th, 2011

  • Initial Release[2]

Notable Features

  • Downloaded over 5000 times[3]
  • No SAS, although SAS module is implemented and generates torque
  • The only engine, the LV-T30 can only be fed by one FL-T500 attached on its top
  • The AV-R8 Winglet is just a fin and can't be used to control the vehicle
  • It is nearly impossible to achieve orbit
  • Kerbin is the only celestial object, does not rotate, and is a mirror reflection of the example planet from libnoise
  • The sun is a directional light source at infinite distance
  • The render distance is only 1500 km, and Kerbin will "sink" into the sky background, vanishing entirely as that altitude is achieved
  • The original Intercontinental Kraken had not been fixed (Moving far from the KSC will result in shaking and even Rapid Unplanned Disassembly due to floating-point precision loss.)

v0.4

Not released[4]

  • The disk terrain generator seen in early releases is implemented from the Libnoise library, giving Kerbin its current global topology (excepting a few later modifications.)

v0.3

Not released[5]

  • The (pre-0.90.0) parts tabs were implemented in the Editor
  • Some terrain was placed in the immediate vicinity of the pad, but Kerbin was still 20 km and smooth beyond it
  • The Mun was removed
  • The game featured an interface including an average propellant gauge, RCS propellant gauge, vertical speed and altimeter, kerbal portraits, g-meter and throttle indicator, most of which did not function
  • An electronic sign, possibly for mouse-over information, appeared; it showed quotes and countdowns in this version

v0.2

Not released[6]

  • Kerbin was a textured 20 km (radius assumed) sphere with no terrain, presumably with 1/900 of its current mass and an orbital speed of less than 442.9 m/s
  • There was a fixed Mun: another textured smooth sphere with little resemblance to the canonical Mun
  • Staging is added
  • Instead of the current vessel-origin rendering system (necessary to solve floating point jitters), the game used the center of Kerbin as the origin
  • The game is now in an early 3D like format

v0.1

Not released[7]

  • The Editor ran in the flight scene, the Vehicle Assembly Building not being implemented yet
  • The RT-10 solid rocket motor was implemented and looks only slightly different from today[outdated]
  • The Command Pod Mk1, TR-18A Stack Decoupler, LV-T30 Liquid Fuel Engine, FL-T500 Fuel Tank, and TT-38K Radial Decoupler are implemented, but barely recognizable
  • Kerbin was a flat, floating tile with generated terrain, and instead of achieving orbit, you could launch past its edge and fall forever into the "void"
  • While the graphics were 3D, the game was 2D, and one could fly and build vehicles only in the altitude-longitude plane, unable to turn north or south, and able to attach parts to only two sides

v0.0

Not released[8]

  • "Kerbal" comes from the name Felipe "HarvesteR" Falanghe gave small figurines he installed in modified fireworks as a teenager[9]
  • HarvesteR was hired by Monkey Squad in 2010 April; the company did not develop software at the time[10]
  • Development of Kerbal Space Program was authorized by Squad co-founder Adrian Goya in 2010 October, but deferred until HarvesteR could be released from marketing set projects in progress[10]
  • Kerbal Space Program first compiled on 2011 January 17[8]
