FENForsty Pro v5.0.0 — Export Engine Overhaul

[BilgeGates]

FENForsty Pro v5.0.0

Highlights

This release delivers a complete overhaul of the export pipeline, major UI features, and significant codebase improvements. The most impactful change is a critical fix to the board export dimension system — for the first time, selecting a physical board size (4cm / 6cm / 8cm) now correctly determines the pixel output of all exported images.

Bug Fixes

• CRITICAL — Export Dimension Bug: Board size selection now correctly maps to pixel output across all quality tiers.
  • Print 8× @ 4cm → 3,776px
  • Print 8× @ 6cm → 5,664px
  • Print 8× @ 8cm → 7,552px
• Fixed incorrect property access in getExportInfo (baseSizeCm → physicalSizeCm, dpi → effectiveDPI)
• Fixed coordinate label borders appearing in exported images
• Fixed coordinate positioning to scale proportionally with board dimensions
• Resolved circular export dependencies across component index files
• Fixed React build errors caused by incorrect component export patterns
