v2.0 — Infoboard

Major rewrite: from a single-display PDF kiosk (Kundenstopper) to a full multi-display digital signage platform. No dedicated player software needed — the display runs in any modern browser.

What's new

Platform

• Renamed to Infoboard
• Multi-display — unlimited screens, each with its own URL (/display/<slug>)
• Multi-zone layouts — split a display into up to 4 zones (7 presets), each with its own playlist
• Migration system — numbered DB migrations for safe upgrades

Content types

• Images (single + galleries with batch upload)
• Local video
• YouTube embeds with configurable quality and options
• Websites via built-in proxy (strips X-Frame-Options/CSP)

PDF improvements

• Switched from client-side PDF.js to server-side rendering via poppler-utils (pdftoppm)
• Parallel rendering across all CPU cores (configurable via render_workers)
• Spread/book view — side-by-side page pairs, per playlist item
• Same-DPI render deduplication (copy instead of re-render)

Admin

• Playlist per display/zone with drag-and-drop ordering and per-item duration
• Tab split: Displays / Inhalte (Medien)
• Display preview thumbnails with zone layout
• Non-blocking PDF upload with background rendering progress
• Ambient blurred background option for image/gallery slides

Upgrading from v1.0

Run ./update.sh on an existing installation. The script will:

• Automatically rename kundenstopper.db → infoboard.db if needed
• Apply all database migrations
• Update dependencies
