This document tracks all public releases of WireTuner, including version highlights, compatibility information, known limitations, and QA status.

Version 0.1.0 - Initial Public Release

Release Date: 2025-11-09 Iteration: I5 - Persistence, File Format, Import/Export, and Platform Parity Status: Release Candidate QA Report: Final QA Report

Highlights

WireTuner v0.1.0 is the first public release, delivering a complete event-sourced vector drawing application with professional-grade tools, unlimited undo/redo, and cross-platform support.

Core Features

  • Professional Drawing Tools

    • Pen tool with Bezier curve creation and handle manipulation
    • Selection tool with click, marquee, and multi-select capabilities
    • Direct selection tool for precise anchor point editing
    • Shape tools: rectangle, ellipse, polygon, and star
    • Sub-30ms tool switching with keyboard shortcuts (V, P, A)

  • Unlimited Undo/Redo & History

    • Operation-based undo grouping with <80ms latency
    • Visual history timeline panel for scrubbing through document operations
    • Infinite history navigation at 5,000 events/sec playback rate
    • Crash recovery with preserved undo/redo stack
    • Automatic snapshots every 1,000 events for fast document loading

  • Import & Export

    • AI Import: Tier-2 feature support (paths, shapes, basic transforms, fills, strokes)
    • SVG Export: Standards-compliant SVG 1.1 output validated with external viewers
    • PDF Export: Print-ready PDF/1.7 documents with vector fidelity
    • Native Format: .wiretuner file format with semantic versioning and SQLite-based persistence

  • Event-Sourced Architecture

    • Complete workflow reconstruction from immutable event log
    • 50ms sampling rate for continuous actions (drag, move, resize)
    • SQLite persistence with ACID guarantees and Write-Ahead Logging (WAL)
    • Automatic CRC32 checksums for data integrity validation

  • High Performance

    • 60 FPS rendering targeting 10,000+ objects
    • Optimized canvas rendering with viewport-aware culling
    • Real-time performance metrics overlay (toggle: Cmd/Ctrl+Shift+P)
    • Save/load operations <100ms on baseline documents

  • Cross-Platform Support

    • macOS 10.15 (Catalina) or later (Intel + Apple Silicon)
    • Windows 10 version 1809 or later (x64)
    • Platform parity validated via comprehensive QA checklist (Platform Parity Checklist)

Downloads

Platform Artifact SHA256
macOS WireTuner-0.1.0-macOS.dmg See release page
Windows WireTuner-0.1.0-Windows-Setup.exe See release page

Installation:

  • macOS: Download DMG, drag WireTuner.app to Applications, launch. Notarized for macOS 10.15+.
  • Windows: Download installer, run setup wizard, launch from Start Menu. Code-signed for security.

Verification: See README - Verifying Downloads for SHA256 checksum validation.

Compatibility & File Format

File Format Version

Forward Compatibility

WireTuner v0.1.0 supports opening files from legacy pre-release versions (v0.0.x) via automatic migration:

  • v0 → v1 Migration: Automatic conversion of unversioned snapshots to versioned format with CRC32 validation
  • Migration Transparency: Users are not prompted; migration occurs seamlessly during document open
  • Migration Log: Events logged to application logs for audit trail

Backward Compatibility

Files saved in v0.1.0 cannot be opened in pre-release versions (v0.0.x). Users must upgrade to v0.1.0 or later.

Downgrade Workflow: Not supported in v0.1.0. Future versions may introduce "Export to v1" functionality with data loss warnings.

Known Limitations

AI Import (Tier-2 Features Only)

Supported:

  • Paths with Bezier curves
  • Basic shapes (rectangles, ellipses, polygons)
  • Solid fills and strokes
  • Basic transforms (translate, rotate, scale)
  • Layering and grouping

Not Supported (Tier-3+ features):

  • Gradients (linear, radial, freeform)
  • Effects (drop shadows, blur, distortion)
  • Advanced path operations (compound paths, clipping masks)
  • Artboards and multiple canvas pages
  • Text objects and typography

Workaround: Pre-process AI files in Adobe Illustrator to expand/rasterize unsupported features before import. See Rendering Troubleshooting Guide for details.

Future Support: Tier-3+ features planned for v0.2 or later.

Platform-Specific Behavior

macOS:

  • Notarization required for macOS 10.15+. Unsigned builds will not launch without Gatekeeper override.
  • Apple Silicon builds use Rosetta 2 emulation (native ARM64 support planned for v0.2).

Windows:

  • Windows Defender SmartScreen may warn about unrecognized publisher. Click "More info" → "Run anyway" for first-time installation.
  • Code signing certificate validation may take 5-10 seconds on first launch.

Performance

  • Large Documents: Documents with >10,000 objects may experience frame rate drops during pan/zoom operations. Enable Level-of-Detail (LOD) rendering in Preferences (future feature).
  • Snapshot Storage: Documents with >100,000 events may exceed 100 MB due to snapshot overhead. Compact event log via "File → Optimize Document" (future feature).

Other Limitations

  • Collaboration: Multi-user editing not supported in v0.1.0 (reserved for future collaboration features).
  • Plugins: Plugin API not available in v0.1.0 (planned for v0.2+).
  • Linux: Linux builds not officially supported in v0.1.0 (community builds may be available).

QA Status

Release Readiness: CONDITIONAL GO - Pending completion of automated test suite and manual QA validation.
