Released on 2018-03-14
This release is mostly just a recompile to make kOS work with KSP 1.4.1, with the few changes that were needed to keep it working, and whatever bug fixes happened to already be implemented when when KSP 1.4.1 came out.
Released on 2018-01-25
This is NOT a release for the most recent KSP. It is a back-port for KSP 1.2.2 so people using Realism Overhaul can use it.
Note, Please take this into account if you are using RP-0 with Realism Overhaul: RP-0 by default does not "cost" the kOS parts properly, so if you have all non-costed parts banned, kOS parts are banned too. This leaves you with only the default disk capacity of 5000 in all avionics parts in RO, which is incorrect. To fix this problem and get reasonable disk capacity, change this line in:
name = kOSProcessor
diskSpace = 40000 // Edited by dunbaratu - was 5000 in defalt RO config which is wrong.

Built for KSP v1.3.1
This release is just to fix one bug introduced by v188.8.131.52 that was discovered post-release by the users, during the Christmas-NewYears time. The fix was quick but release was delayed for after the holidays.
None that we know of. This change shouldn't even require recompiling KSM files, presuming you had them recompiled already for v184.108.40.206.

This release was primarily focused on speedups and smoothness of execution. We welcomed a new developer (github username @tsholmes) who contributed a lot of bottleneck analysis and code speedups. The goal was to reduce the burden kOS causes to the physics rate of the game, and consequently also allow tech tree scaled performance by era for the kOS computer parts themselves (slow at first, faster later).

global, creating a variable that you could see from anywhere outside that program file.

global. (The variables magically created via the lazyglobal system will still be global just like they were before.)

For this release we instituted a rule partway through that only bug fixes should be allowed (some of the first few changes were enhancements rather than bug fixes, but after that, its all bug fixes). This was in a vain hope that doing so would get a release out faster than normal.
(Can't think of any.)

CKAN info inside the ZIP was wrong for v1.1.1 (it had a max version number smaller than current version number, so CKAN refused to pick it up). This corrects that problem.

This release is nearly identical to v1.0.2, except that it was compiled against binaries from KSP v1.2.2 (released just before we published) and the version numbers have been advanced. While it appears that kOS v1.0.2 is compatible with KSP v1.2.2, we wanted to err on the side of caution and provide an explicitly compatible release. Please review the changelog for v1.0.2 if you are upgrading from an earlier version.

We wanted to get the last bug fixes and new features into the hands of any users who might not update KSP to 1.2 right away. Traditionally there are some mods that take a while to update when KSP releases a new version, and many users choose to wait for all of their favorite mods to update before upgrading KSP. By releasing in conjunction with the update, we can ensure that as many users as possible have access to these latest updates. We will be releasing a version of kOS that is compatible with KSP 1.2 as soon as possible after the final build is released to the public.
stagecommand/function now implements the yield behavior, waiting until the next physics tick to return. This ensures that all vessel stats are updated together. (https://github.com/KSP-KOS/KOS/pull/1807)

Hey let's stop calling it Beta
@Dunbaratu Dunbaratu released this 3 hours ago About the name:
kOS has been around long enough that we figured it was long overdue for us to stop calling it 0.something. Lots of people are using it, and we're worried about backward compatibility enough that we're not really treating it like a Beta anymore. This version contains mostly a few things that we knew might break backward compatibility so we'd been putting them off for a long time. A jump to 1.0 seems a good time to add those changes.
Of course, it has lots of other changes for whatever else was being worked on since the last release. BREAKING CHANGES
As always, if you use the compiler feature to make KSM files, you should recompile the KSM files when using a new release of kOS or results will be unpredictable. New Subdirectories ability has deprecated several filename commands such as delete, copy, and rename. They will still work, but will complain with a message every time you use them, as we may be removing them eventually. The new commands deletepath, copypath, and movepath described below are meant to replace them. When using a RemoteTech antenna that requires directional aiming, in the past you could aim it at mission control with SETFIELD("target", "mission-control") and now you have to say SETFIELD("target", "Mission Control") instead, due to changes in RT's naming schemes. Previously the Y and Z axes of SUN:VELOCITY:ORBIT were swapped. (#1764) This has been fixed so it is now the same as for any other body, however scripts might exist that had previously been swapping them back to compensate for this, and if there were they would now break since that swapping is no longer needed.
Subdirectories: (http://ksp-kos.github.io/KOS_DOC/commands/files.html) You are now able to store subdirectories ("folders") in your volumes, both in the archive and in local volumes. To accomodate the new feature new versions of the file manipulation commands had to be made (please go over the documentation in the link given above). In the Archive, which is really your Ships/Script/ directory on your computer, these subdirectories are stored as actual directories in your computer filesystem. (For example, the file 0:/dir1/dir2/file.ks would be stored at Kerbal Space Program/Shipts/Script/dir1/dir2.file.ks on your real computer.) In local volumes, they are stored in the persistence.sfs savegame file like usual. (Pull Request discussion record: #1567) Boot subdirectory: (http://ksp-kos.github.io/KOS_DOC/general/volumes.html#special-handling-of-files-in-the-boot-directory) To go with Subdirectories, now you make a subdirectory in your archive called boot/, and put all the candidate boot files there. When selecting a boot file in the VAB or SPH, the selections are taken from there and need not contain the "boot_" prefix to the filename anymore. Old boot files will be grandfathered in that are named the old way, however. CORE:BOOTFILENAME is now a full path. i.e. boot/myfile.ks. PATH structure now allows you to get information about the new full subdirectories system from your scripts. (http://ksp-kos.github.io/KOS_DOC/structures/volumes_and_files/path.html) New RUNPATH command now allows any arbitrary string expression to be used as the name of the file to be run. i.e. set basename to "prog". set num to 1. runpath(basename+num, arg1). // same as run prog1(arg1). As part of the support for this, programs with a large number of RUN commands (or RUNPATH commands) should now take up a bit less of a memory footprint than they used to in their compiled form (and thus in KSM files too). (http://ksp-kos.github.io/KOS_DOC/commands/files.html#runpath-and-runoncepath) Communication between scripts on different CPUs of the same vessel or between different vessels. (http://ksp-kos.github.io/KOS_DOC/commands/communication.html) A new structure, the Message, contains some arbitrary piece of data you choose (a number, a string, a list collection, etc), and some header information kOS will add to it that describes where it came from, when it was sent, and so on. What you choose to do with these arbitrary chunks of data is up to you. kOS only lets you send them. You design your own protocol for what the data means. If RemoteTech is installed, a connection is needed to send a message to another vessel (but not to a CPU on the same vessel). And, the message won't actually show up in the other vessel's queue until the required lightspeed delay. To handle KSP's inability to have different vessels far away from each other both fully loaded and active, you do have to switch scenes back and forth between distant vessels if you want them to have a conversation back and forth. Messages that were meant to arrive on a vessel while it wasn't within active loading range will wait in the recever's vessel queue until you switch to it, so you don't have to hurry and switch "in time" to get the message. Added anonymous functions : (http://ksp-kos.github.io/KOS_DOC/language/anonymous.html) By placing arbitrary braces containing the body of a function anywhere within the script that an expression is expected, the compiler builds the function code right there and then returns a delegate of it as the value of the expression. New 3rd-party addon framework (https://github.com/KSP-KOS/KOS/tree/develop/src/kOS/AddOns/Addon%20Readme.md) allows authors of other KSP mods to add hooks into kOS so that kOS scripts can interface with their mods more directly, without kOS developers having to maintain that code themselves in the kOS repository. (Pull Request discussion record: #1667) allow scripted vessel launches KUNIVERSE:GETCRAFT(), KUNIVERSE:LAUNCHCRAFT(), KUNIVERSE:CRAFTLIST(), and KUNIVERSE:LAUNCHCRAFTFROM() allow you to script the changing of scenes and loading of vessels into those scenes. While this breaks the 4th wall quite a bit (how would an autopilot choose to manufacture an instance of the plane?), it's meant to help with script testing and scripts that try to repeatedly run the same mission unattended. (http://ksp-kos.github.io/KOS_DOC/structures/misc/kuniverse.html) eta to SOI change: Added SHIP:OBT:NEXTPATCHETA to get the time to the next orbit patch transition (SOI change). (http://ksp-kos.github.io/KOS_DOC/structures/orbits/orbit.html#attribute:ORBIT:NEXTPATCHETA) get control-from: Added SHIP:CONTROLPART to return the Part of the vessel that is currently set as its "control from here" part. (http://ksp-kos.github.io/KOS_DOC/structures/vessels/vessel.html#attribute:VESSEL:CONTROLPART) maneuver nodes as a list:( New ALLNODES bound variable that returns a list of all the currently planned manuever nodes (the nodes you could iterate through with NEXTNODE, but rendered into one list structure). (http://ksp-kos.github.io/KOS_DOC/bindings#allnodes) Several new pseudo-action-groups (akin to "panels on", that aren't action groups as far as stock KSP is concerned, but kOS treats them like action groups) were added. (http://ksp-kos.github.io/KOS_DOC/commands/flight/systems#kos-pseudo-action-groups) Ability to get/set the navball mode (surface, orbital, target) with the NAVMODE bound variable: i.e. SET NAVMODE TO "SURFACE".. UniqueSet structure. (http://ksp-kos.github.io/KOS_DOC/structures/collections/uniqueset.html) A collection intended for when all you care about is whether a equivalent object exists or doesn't exist yet in the collection, and everything else (order, etc) doesn't matter.
In some cases (#1661) the program wouldn't stop immediately when you execute a kuniverse command that reloads a save or switches scenes. It would instead finish out the remainder of the IPU instructions in the current physics tick. After the fix, causing a scene change (or reload) automatically stops the program right there since anything it does after that would be moot as the game is about to remove everything it's talking about from memory. If using "Start on archive", with Remote Tech, a misleading "power starved" error was thrown when you reboot a probe that's out of antenna range. (#1363) unchar("a") was apparently broken for a few months and we hadn't noticed. The root cause was that its implementation had to be edited to comply with the change that enforced the VM to only use kOS Structure types on the stack. The need for that change had been missed. (#1692) Previously Infernal Robotics allowed you to move servos that weren't even on your own vessel and you shouldn't have direct control over. This has been fixed. (#1540) Refactored previous non-working technique for quicksave/quickload to turn it into something that works. (#1372) There were cases where using CTRL-C to abort a program would cause some old cruft to still be leftover in the VM's stack. This made the system fail to clear out the names of functions that were no longer loaded in memory, making it act like they were still reachable and call-able. (#1610) Some types of Resource didn't contain the :DENSITY suffix like the documentation claimed they would. (#1623)
Released on 2016-05-16
The biggest reason for this release is to handle two game-breaking problems caused by recent alterations in the API that kOS hadn't adapted to correctly yet.
The "remit" of this release is purely to fix a few bugs, and patch up a few things where KSP 1.1 had changes we didn't catch. Mostly, that's cases where previously working code in kOS had now become a bug, but it also includes a few other bug fixes not related to KSP 1.1.
But any new features (rather than bug fixes) in the pipeline not directly related to that "remit" are not in this release.
