- Layout cards have a toggle for the set-up measurements. It is off by default and the setting is saved on your device
- The Game Tracker setup has a new Create the Battlefield step (after Force Disposition) where you can select the layout in play; a map button on the board reopens it during the game
- Fixed the tracker's first-turn step to match the Chapter Approved rules: the roll-off winner takes the first turn, there is no separate choice anymore

Version 4.2
Released: July 3, 2026What's New:
- Made the website more accessible for all types of gamers: the mission card, rules and browsing pages now work fully with a keyboard and with screen readers, with visible focus outlines, a skip-to-content link, and animations that respect your system's reduced-motion setting (the Game Tracker is next)
- Every 11th edition primary and secondary mission card page has a new Card text section: the card's complete rules as readable, selectable text — including the Objective Actions printed on the back of double-sided cards
