0.5.7 (2026-06-16)¶

Optimized diagram export system (PDF/PNG/Markdown) and AI model availability audit.

✨ Features¶

PDF export file size reduced from 150–200 MB to ~1–5 MB using high-quality 2x PNG rasterization instead of uncompressed bitmap capture.
Markdown export now includes diagram description and project metadata when the corresponding options are selected.
PDF and PNG exports include a corporate-styled header with diagram title (always), project/folder/author info (when selected), and a footer with export date and "Powered by Diagramahub" branding.
PDF description sections render Markdown as formatted HTML (headings, bold, lists, tables, etc.) instead of showing raw Markdown syntax.
Export buttons show individual loading spinners per format instead of all buttons changing to "Exporting" simultaneously.
jsPDF is now lazy-loaded for faster initial page load and smoother PDF export experience.

Export logic extracted from DiagramEditorPage.tsx into dedicated utility modules: ExportService, PDFGenerator, MarkdownExporter, DescriptionRenderer, MetadataHeader.
Export state management changed from single boolean to per-format tracking for cleaner UX.
