Charts & Diagrams: Native support for geml-chart and inline Mermaid diagram rendering. Math Equations: Beautiful mathematical typesetting using KaTeX. Diagnostics Banner: View build-time reference checking and validation errors directly in the browser. Version History: Visualize .gemlhistory sidecar files to understand document evolution. [Version 1.3.7 Update] bundles the GEML 1.12.3 parser and tightens how links, media and translation are handled. Transclusions now follow up to 16 levels, and very large documents no longer freeze the tab. some bug fix.
