v0.2.3 Beta 6

We have just released the 6th beta of KSP2 Redux, which adds a large batch of new parts including SM+ decouplers, boosters, command pod, probe cores, cameras and decals, EVA parachutes, vessel categories and map icons, KSP1-style orbital camera behavior, expanded maneuver node controls, campaign flag changing, supersampling, major SDK tooling improvements, a Lua-powered Patch Manager rewrite, and as always, a ton of bugfixes and quality-of-life improvements.

To install, use the Redux Updater app, do not download any files from this page manually.

Mod Breaking Changes

Patch Manager scripting was rewritten to use Lua. All existing patches will need to be rewritten in Lua, but the new system is more powerful and easier to learn.
Config registration was moved to the newer Redux/SpaceWarp config system. Mods using low-level config registration APIs may need to update.
UitkForKsp2 package names, namespaces, assemblies and theme structure were reorganized. Mods directly referencing old control namespaces or theme paths may need updates.
Part size handling was revamped. Mods or patches relying on old legacy part sizes should update their part metadata.
