How to read this
The timeline is newest-first. Patch numbers follow the in-game version (1.0 launch → 1.0.2 → 1.0.3 → 1.0.4). Verification milestones — like the all-nine Ultimate Perks confirmation — are listed alongside patches because they change what the guides can assert as verified.
When a patch touches a mechanic a guide covers, that guide's Verified on version stamp is bumped and the change is noted in the linked entry. If a number in a guide no longer matches your patch level, the about page explains the 60-day re-verification rule that flags stale guides automatically.
