✨ v0.17.0

🎨 Big Update: Smarter Color Comparison!

This release brings a major improvement to how Vizzly detects visual differences. We've upgraded from YIQ-based color comparison to CIEDE2000 (ΔE00) - the industry standard for perceptual color difference.

Why does this matter?

The old YIQ threshold was... kind of broken. A threshold of 0.1 let almost anything through, while 0.001 was so strict it flagged tiny run-to-run variance as failures. There was no sweet spot!

CIEDE2000 fixes this with an intuitive scale where 1.0 = the Just Noticeable Difference (JND). Colors that look different to humans will be detected as different, and colors that look the same won't trigger false positives.

⚠️ Breaking Change: New Threshold Scale

What	Before	After
Unit	YIQ normalized (0.0-1.0)	CIEDE2000 Delta E
Default	0.1	2.0

New threshold reference:

• 0.0 = exact pixel matching (strictest)
• 1.0 = Just Noticeable Difference - very strict
• 2.0 = recommended default (ignores sub-pixel rendering variance)
• 3.0+ = more permissive

What's Changed

• ✨ Upgrade to honeydiff v0.5.0 with CIEDE2000 color difference (#105)
• 🐛 Fix threshold propagation - comparison.threshold now properly passed to cloud builds (#104)
• 🔧 UI improvements - Hide view mode toggle on mobile, add firefox-mobile test config

Migrating

If you have a custom threshold configured:

• Default (0.1) → Use 2.0
• Very strict (0.01) → Try 1.0 (JND)
• Permissive (0.5+) → Try 4.0-6.0

Test and adjust based on your needs!
