Latest documented build1.21.0
Current statusVersion 1.21.0 documents support for The Swarm data
Patch-readiness noteVersion 1.21.0 adds The Swarm data mappings; narrow edge cases can still need follow-up fixes.
Known notesThe update adds current item, reward and JSON mappings without announcing a save-format overhaul.
Compatibility note
Patch-day gaps happen
Fresh updates can leave some rewards, parts or save fields incomplete for a while even when the core editor still works.
Compatibility note
Game Pass can change faster than Steam or GOG
If save detection breaks on Game Pass, check the current path before you assume the editor itself is broken.

Known limitations
Known limits and patch lag.
New rewards, items and platform quirks do not always arrive at the same speed.
- Major No Man's Sky updates can add items, rewards or JSON sections faster than the editor mappings are updated.
- Game Pass and Microsoft Store save paths can change, so save discovery is not equally stable across all platforms.
- PS4 editing still depends on Save Wizard and follows its own workflow.
- Raw JSON, mission repair and seed-level edits are advanced work.
- Community workarounds and hotfixes can exist, but they are not the same thing as official GoatFungus files.
