Update Cadence and Developer Communication

Since Early Access launch, the team has maintained a predictable release rhythm. Major versions (0.x.0) arrive every six to eight weeks and typically center on a single headline system or world. Smaller hotfix patches (0.x.1 through 0.x.5) land between majors, addressing bugs and occasionally slipping in minor features.

Director Kjun and the community team post developer letters before each major release, outlining goals and soliciting feedback through the official Discord server and Steam forums. The April 17 and April 24 community letters formally realigned expectations for 2026: full 1.0 launch is now targeted for early 2027, the PlayStation 5 release is treated as a parallel priority alongside 1.0, and the May 2026 patch will not be a major content release. See 2026 Roadmap for the realigned plan and PlayStation 5 Version for the platform timeline.

Mod Compatibility After Each Patch

Every inZOI update auto-disables all installed mods on patch day. Players must re-enable mods through the in-game mod manager after each update. KRAFTON has confirmed this is permanent policy: incompatibilities surface explicitly rather than as silent crashes. The official ModKit supports custom meshes, textures, animations, accessories, and face presets, with Lua scripting support targeted for December 2026.
