Just in time for the holidays! I'm very pleased to announce the 23rd update to KSP is now available.
This update, as you all probably already know, was mainly focused in smoothing out the features we've added all through this year, patching up long-standing bugs, doing optimizations, and adding a few new features that were long awaited.
* The Science Archives:
Browse through all the science you've done in your Career games in this new section of the R&D Facility.
Several parts can now be tweaked individually by right-clicking them during construction, allowing for entirely new possiblities in spacecraft construction.
* Science Revisited:
We've revised the way experiments are performed, stored and transmitted based on the feedback we got from the last release, to make Science much more engaging and interesting. Endlessly-repeatable transmissions that would let you max out a subject in a single mission are a thing of the past now.
* The Lab Module:
With experiments and transmissions no longer being freely repeatable, we've added the Lab Module to let you process your science data on the field, increasing the science gained by transmitting it. The Lab also allows you to reset single-use modules such as the Goo Canister and Materials Bay, since those will now become inoperable if their data is removed for transmission.
* The R.A.P.I.E.R. Engine:
The new 'Reactive Alternate-Propellant Intelligent Engine for Rockets' is a hybrid propulsion system that can run on external intake air while flying through the atmosphere, and will switch to internal oxidizer supply as you leave the atmosphere behind.
* EVA Data Collection:
Kerbals on EVA are now able to collect and store data from experiment modules and other science containers, including other EVAs.
* Part Tooltips Overhaul:
The old tooltips seen when hovering over part icons in the R&D or construction facilities have been completely overhauled. The new layout is a lot easier on the eyes and organizes information much more efficiently, making it easier to compare stats between parts and seeing what does what.
* All-Around Optimizations:
We've gone over a huge amount of code this time, to make sure the game is doing things as efficiently as possible. The optimizations were mainly focused around sources of lag with high part counts, so the game should be smoother around large ships. (Your mileage may vary, as no hardware setup is quite the same).
* 6-DOF Device Support for Windows:
Few games can benefit from a 6-degrees-of-freedom input device such as the Space Navigator like KSP. Seamless transition/rotation camera control on all scenes, plus pitch-roll-way and linear XYZ inputs in flight control mode, allowing for an unprecedented level of control. This feature is Windows-only for the time being, but we're ready to implement OSX and Linux support as soon as the drivers become available.
Plus a heap of other additions and fixes. Check out this article for the complete changelog.
Steam players should be automatically updated. (Might be a few minutes. Restart Steam if it's taking too long).
Compatibility with previous versions:
We haven't had to bump the last-compatible versions on this update, so all previous saves and craft files should work just fine through the update. Do keep in mind mods may not work correctly, so it's always advisable to start out with a clean, unmodded install.
Happy Launchings, and Happy Holidays!
