Material changes

  1. Evidence and review status

    Source records and review labels now distinguish retrieved originals, unchecked links, legacy content and publication on explicit instruction. The displayed status applies to the exact article version.

  2. Milestones and terminology

    The central FRMCS milestone dataset now drives public summaries. Planned dates are explicitly separated from releases, regulatory incorporation and operational rollout.

  3. Core reference content

    The GSM-R/FRMCS comparison and the principal knowledge guides were revised in English and German. Migration guidance, multi-vendor operations, architecture interfaces and standards status were made more precise.

  4. Public discovery and machine-readable output

    Site search, feeds, Markdown output, agent-readable files, language alternates and structured data were aligned with the same public, non-demo content.

  5. Mobile presentation

    Public tables use stacked records on smaller screens, and navigation and long-form reading were checked for narrow mobile viewports.

  6. Glossary and abbreviations

    Fifteen existing glossary entries were revised and 28 new entries were added, bringing the glossary to 45 entries in each language. Where the meaning is unambiguous, first mentions now receive a same-language explanation or link directly to a glossary or directory definition. Grouping, search and stable anchors make terms and profiles easier to find; context-dependent abbreviations are not resolved globally.
