Core Rules Data Changelog

How the Core Rules data evolved, from the free PDF through every app data version.

The Core Rules shown in this app are generated from the official app data export. Each entry below is one data version; the changes listed are for the Core Rules only (most data versions only touch faction and points data). The PDF entry at the bottom describes how the first export differs from the freely available Core Rules PDF.

The Core Rules PDF

2026-06-18

Baseline: the freely available Core Rules PDF, superseded by the first app data export (version 867).

  • 103 numbered third-level sub-rules (NN.NN.NN) were introduced — 16 restructured from PDF sidebars and inline text, the rest new clarifications. In the rules browser they carry PDF/APP source badges accordingly.
  • Of the 162 PDF rules: 48 are unchanged, 44 gained additional content around the PDF text, and 70 were reworded or restructured.
  • Eight PDF sidebars were not carried over (Indirect Fire, Do Units Have To Fight?, Overrun Fights, New Foes To Face, Plunging Fire, Hold At All Costs, Where To Find Actions, Rapid Disembark). This app restores them as PDF-badged callouts on their rules.
  • Cross-references now use rule numbers (e.g. “(03.03)”) instead of the PDF's page positions (“see left/below/opposite”).
  • All 25 sections gained introductions, and every rule is provided in eight languages.
