Full release notes(18 changes)

New features

6
  • 11th Edition missions: Each army can select only the Force Dispositions provided by its detachments. The matchup automatically resolves a different Primary Mission for each player and a legal terrain layout.
  • Secondary missions: Play without secondaries, choose two Fixed missions for the battle, or use a Tactical deck that draws two new cards during each Command phase.
  • Modern mission cards: Browse complete, readable mission rules and choose Fixed secondaries from the same updated card modal used across GrimSlate.
  • Live battle dashboard: Track the active player, battle phase, Primary and Secondary VP, objective control, Command Points, rounds, and game timer.
  • Local and multiplayer battles: Control both armies on one device or share a join code for synchronized play on separate devices.
  • Quick Battle: Start a lightweight VP and round tracker without mission, CP, objective, or event-log overhead.

Improvements

5
  • The creation wizard now validates edition, battle size, points, army contents, Force Dispositions, and terrain compatibility before creating or joining a game.
  • Fixed secondary selection now stays inside Mission Setup instead of adding another wizard step, with a final configuration summary before battle.
  • Quick Match selects a legal Force Disposition automatically and resolves random battle roles once when the game is created.
  • Battle card images are delivered as text-legible AVIF assets optimized for fast loading.
  • Battle Mode loads stratagems and rules from every selected 11th-edition detachment.

Bug fixes

3
  • Fixed multiplayer joins creating an active game before its mission configuration was ready.
  • Fixed starting Command Points, random first-turn resolution, guest editing permissions, and leaving an 11th-edition game.
  • Fixed stale or incompatible rosters and Force Dispositions remaining selected after changing battle size or army.

  • Command Search: A new global search palette brings together factions, datasheets, rules, your army lists, community lists, and player profiles in one place.
  • Keyboard-first navigation: Open search with ⌘ K / Ctrl K or the / shortcut, then use the keyboard to find and open a result.
  • Search health analytics: Privacy-safe, consent-aware metrics now measure search adoption, zero-result searches, and result selection without collecting search terms.

Improvements

4

  • Responsive navigation: The compact drawer and bottom navigation remain available through compact laptop widths, preserving space for content and actions.
  • Mobile search: Search and notifications are grouped as global actions, Command Search has safe side margins, and navigation controls have more comfortable touch targets.
  • Scrolling: The toolbar now stays legible over rich page content with an opaque background and subtle elevation after scrolling.
v4.0.2

Smarter Roster Building

Full release notes(9 changes)

New features

2
  • Maximum points filter: Enter any points limit in the unit picker to show only datasheets whose cheapest configuration fits that budget.
  • Use remaining points: Apply the roster's current remaining allowance directly from the Filters panel, including the separate allowance for allied units.

Improvements

2
  • Active filters display the current points ceiling and empty results explain which points limit excluded the available units.
  • Clearing filters now also resets both custom and remaining-points limits.

Bug fixes

2
  • Fixed The Silent King not being recognized as a Character and Supreme Commander, preventing automatic Warlord selection.
  • Improved generated Epic Hero data so combined character units retain the Character keyword when it is stored only on a nested model.
v4.0.1

  • Keyword conditions: Set whether the attacker charged, remained stationary, is within half range, is beyond 12 inches, or cannot see the target for Lance, Heavy, Melta, Rapid Fire, Conversion, and Indirect Fire.

  • Random characteristics such as D6+2, Rapid Fire D6, and Sustained Hits D3 now use their correct statistical averages.
  • Permanent invulnerable saves are preferred over temporary or conditional defensive abilities.
  • 11th Edition Cover now applies −1 to Hit, each attack uses one save roll checked against InSv and modified armour, and Psychic weapons ignore negative Hit modifiers.

Bug fixes

4
  • Fixed Anti weapon abilities being applied even when the defender did not have the required keyword.
  • Fixed Cover and Stealth incorrectly modifying melee attacks.
  • Fixed Torrent attacks showing a hit-roll target despite hitting automatically.
  • Fixed source-data formatting variants such as Twin Linked, Anti Vehicle 3+, and Anti-fly 2 not being recognized.
