System-by-system comparison
| System | Key update | Current consequence |
|---|---|---|
| Stealth | Update 12 | Lighting and gradual detection matter; crouched archery remains possible. |
| Perks | Updates 13–15 | Clearer menus lead into complete skill ladders and a much larger roster. |
| Alchemy | Updates 14–16 | Vendor cleanup, harvesting flow and ingredient filters reduce inventory friction. |
| Co-op | Updates 13–16 | Host settings, guest character saves and broader sync fixes define the current model. |
| Companions | Update 16 | Permadeath is optional and off by default; markers and persistence improved. |
What older guides commonly miss
- They may assume detection is binary or that bow aiming breaks crouch.
- They may reference the pre-overhaul perk menu or retired perk names.
- They may treat guest growth as disposable or companion death as mandatory.
