A conservative tracker for what is included at Early Access launch, what Unknown Worlds has now placed on the Early Access roadmap, and what still needs verification after each patch.
What the first Early Access build contains based on official store and launch-window reporting.
The 5/15 roadmap now gives the tracker concrete update buckets instead of only broad future categories.
How this site should handle claims before they become reliable wiki facts.

No official Hotfix 4 or EA1.1 patch note was found in the source pass. Hotfix 3 remains the latest patch baseline. The June 29 Steam review API still reads Very Positive with 108,954 positive / 10,624 negative / 119,578 total all-language reviews. Competitor sitemaps stayed stable except for subnautica2.gg moving to 666 URLs, mostly reinforcing item/blueprint breadth and its Farming Planner surface rather than justifying thin copied entity pages.
No official Hotfix 4 or EA1.1 patch note was found in the source pass. Hotfix 3 remains the latest patch baseline. The June 16 Steam review API still reads Very Positive with 106,228 positive / 10,306 negative / 116,534 total all-language reviews. Recent English review samples still point at broad content-length, optimization, and co-op expectation themes, while tracked competitor sitemaps showed no newer entity wave.
No official Hotfix 4 or EA1.1 patch note was found in the source pass. Hotfix 3 remains the latest patch baseline. The June 13 Steam review API still reads Very Positive with 105,270 positive / 10,209 negative / 115,479 total all-language reviews. Recent review samples still point mostly at optimization/FPS and Early Access content-length complaints, while tracked competitor sitemaps showed no entries modified since June 11.
No official Hotfix 4 or EA1.1 patch note was found in the source pass. Hotfix 3 remains the latest patch baseline. The June 10 Steam review API still reads Very Positive with 104,307 positive / 10,093 negative / 114,400 total all-language reviews, and Steam appnews also surfaced the June 2-9 SteamDB top-sellers list with Subnautica 2 still in the top ten.
No official Hotfix 4 was found in that source pass. Hotfix 3 remained the latest patch baseline, the June 4 Swimming Forward dev vlog remained the latest roadmap-cadence signal, and the June 7 Steam review API was the newest verified review checkpoint for that pass.
Sub2Wiki added a source-backed news summary for the June 4 Swimming Forward dev vlog so "Subnautica 2 next update", "EA1.1 update", and "Swimming Forward" searches land on a clear page instead of a patch-note guess.
Unknown Worlds says the team is pivoting from frequent rapid hotfixes toward the EA1.1 update, expected in a few weeks. Treat this as a roadmap and cadence signal, not a new patch note.
