Demo 7.0, in the 4 Jun 2026 news, reworked run settings, the settings menu, the pause menu, jump physics, the death screen, Discord rich presence, and item labels. 1.0.1's gameplay fixes are listed on the troubleshooting page. The same 1.0 news says the demo stays online without further feature updates.

When a patch changes a guide, I would rather update the guide than leave a stale number. The pages this 1.0.1 note touches are troubleshooting, the nanotech scanner step in the mercenary ending, and the lockpick behavior already changed in 1.0.
