The milestones
- July to October 2025: demo builds v0.2 and v0.3, Steam Next Fest and Tokyo Game Show. The release date slipped from 21 November to 12 December.
- 12 December 2025: Early Access at $17.99 with the Dispatch Portal, Experimental Cauldron and Knowledge Altar new since the demo. 50,000 copies in six days.
- 23 to 30 December 2025: a week off Steam after a DMCA notice over a third-party music track, while v0.4.1 crash fixes were being rushed out.
- January to April 2026: Steam Workshop, Sandbox Mode, the Transmuter and Steam Boiler, night-time customers and the Ledger.
- June 2026: v0.5.4467 rewrote the conveyor system and rebalanced recipes around four catalysts; the previous build was kept as a rollback branch because cauldron outputs changed.
- 8 September 2026: Version 1.0 with Wagons, the Grand Portal, Brew Barrel, Shop Recognition, multi-storey customers and a multiplayer lobby, then Hotfix 1.0.4917 the same day.
Reading old guides against this table
Because two patches changed recipes (April preview, June rebalance) and 1.0 moved unlocks to the Workbench, the date on any video or post matters. Anything about cauldron outputs recorded before June 2026 may have changed; anything showing catapults or bridges in the research tree is pre-1.0. Every number on this site that came from a guide carries the version it was measured in for that reason.
