Player Impact
Who should check first?
World rules, MOD compatibility, and old server settings need a second look.
| Audience | Main impact | Next check |
|---|---|---|
| Returning players | Expect a more configurable survival experience, new official presets, item progression changes, new POIs, and UI/crosshair improvements. | Read this brief, then open the official release notes. |
| Mod users | Major updates can break XML edits, UI changes, progression mods, and overhaul packs. | Use the mod compatibility checklist before loading an old save. |
| Server owners | Several old serverconfig-style settings now need to be recreated through sandbox options and copied as SandboxCode. | Review the server config guide before editing a live server. |
| MOD authors | V3.0 includes modding-facing changes around core assemblies, localization file naming, XML formats, and XUi internals. | Mark templates and XPath edits as version-sensitive until tested. |
| New players | The new sandbox choices can be helpful, but too many settings can distract from learning the basic loop. | Start with the guide board, then change settings gradually. |
