Arcline Desktop v0.3.0

[0.3.0] - 2026-07-12

Added

• A full-stack Robotics discipline with robot platforms, perception and navigation sensors, real-time compute, independent safety control, protected power, drives, encoders, operator controls, ROS 2 nodes, and dedicated semantic connectors.
• Professional robot system-stack and wiring starters with continuous power, safety, fieldbus, motion-command, and feedback paths.
• Chip-aware electrical schematic symbols and starters, plus ISO-oriented mechanical drafting symbols for holes, slots, dimensions, datum, GD&T, surface finish, welds, and title blocks.
• Animated marketing workflow stories that demonstrate system modeling, linked specifications and backlinks, and guided presentation paths.

Changed

• Expanded the professional engineering catalog to 167 symbols and 54 discipline-aware connector presets across Networking, DevOps, Electrical, Mechanical, Robotics, and Machine learning.
• Reorganized the shape browser into eight focused disciplines: Software, Cloud, Data & AI, Networking, DevOps, Electrical, Mechanical, and Robotics.
• Improved terminal-aware connector placement, orthogonal routing, symbol proportions, template fidelity, and label clearance for professional schematics.
• Updated Arcline's public identity to “Diagram the system. Any Discipline. Explain the architecture.” with stronger search metadata and a matching social preview.
• Improved desktop packaging reliability on macOS and kept platform-specific downloads routed through the public release repository.

Verified

• Production builds, static-site checks, desktop transport tests, template architecture checks, and marketing animation regression tests pass for the release.

Arcline Desktop v0.2.1

Desktop downloads

Choose the installer for your platform:

• macOS (Apple silicon): Arcline.Desktop-0.2.1-arm64.dmg or the ZIP alternative.
• Windows: Arcline.Desktop.Setup.0.2.1.exe for the installer, or Arcline.Desktop.0.2.1.exe for the portable build.
• Linux: Arcline.Desktop-0.2.1.AppImage for a portable app, or the .deb package for Debian and Ubuntu.

The macOS packages were rebuilt on July 12, 2026 to correct an invalid app-bundle signature. They are integrity-checked and ad-hoc signed, but are not yet Apple-notarized. On first launch, drag Arcline Desktop to Applications, Control-click it and choose Open. If macOS still blocks it, open System Settings → Privacy & Security and choose Open Anyway for Arcline Desktop. A fully silent first launch requires an Apple Developer ID certificate and notarization.

Windows may show SmartScreen until an Authenticode certificate is configured. Choose More info → Run anyway only after verifying the checksum. On Linux, make the AppImage executable with chmod +x Arcline.Desktop-0.2.1.AppImage.

Verify every download against SHA256SUMS-v0.2.1.txt before installing.

0.2.0 - 2026-07-12

Added

• A first-class architecture specification workspace with Visual and Markdown editing, starter documents, code blocks, and Word, Google Docs-ready, Markdown, HTML, and text exports.
• Stable @{name} references from specifications to diagrams, nodes, connectors, and other specifications, including live previews and bidirectional canvas backlinks.
• An editable presentation storyboard with path-by-path animation, reorderable beats, simultaneous one-to-many connector groups, autoplay, focus framing, and reduced-motion support.
• 56 semantic architecture, UML, cloud, data, and agent shapes; 338 AWS and Kubernetes provider icons; six editable agentic patterns; eight UML connector semantics; and four user-pinnable toolbar shortcuts.
• A distributable Arcline agent skill for Codex and Cursor, validated result envelopes, patch audits, and a browser-agent import bridge that requires no model API key in Arcline.
• Mermaid import and export for flowcharts, class, sequence, state, and ER diagrams, plus PlantUML import and live import previews.
• Full-fidelity SVG, PNG, and print/PDF export with semantic shapes, routed connectors, arrow markers, embedded images, annotations, and active visual themes.
• Point-in-time review and editable-copy share links that keep the compressed project in the URL fragment.
• Twelve nondestructive visual modes: Professional, Midnight, Ocean, Cat, Dog, Technical, Patent, Sloppy, Grayscale, Black & White, ASCII, and Animated.
• An Electron desktop shell with encrypted offline collaboration over local Wi-Fi or a phone hotspot, plus Bluetooth Low Energy transport on macOS.
• A crawlable marketing site, structured product and FAQ data, sitemap, robots directives, and an LLM-readable product summary.

Improved

• The canvas is effectively unbounded, with large-diagram Fit support and connector layers that expand around content.
• Connector arrowheads, labels, route dragging, double-click point creation, direct label movement, and export parity.
• Pattern layouts, grouping, inspector scrolling, project previews, architecture checks, checkpoints, reusable subsystems, themes, and the primary shape toolbar.
