Version 1.6.9

RawCull Changelog — v1.6.8 → Latest

Version 1.6.9 is submitted for update on Apple App Store

From: v1.6.8
To: latest commits

✨ What’s new

• Toggle zoom preview source with the J key
  • In a zoom window, press J to switch between:
    • cached thumbnail (fast default), and
    • embedded full-resolution JPG extracted from RAW.
  • Default now starts on cached thumbnail for faster initial interaction.
  • Reference: RawCull/Views/ZoomViews/ZoomOverlayView.swift (noted around lines 26, 103)

🔄 Changed behavior

• Zoom preview source is now per-window (not global)
  • Removed Settings → Thumbnail Sizes toggle: “Use Thumbnail for Zoom”.
  • Source selection is now done directly in each zoom window via J.
  • This enables side-by-side/per-image comparison without committing to a global app setting.

⚡ Performance & cache improvements

• Catalog scanning no longer evicts thumbnails you’re actively likely to browse
  • Previous behavior on large catalogs could overflow RAM cache during scan preload, evict many items, and cause heavy re-extraction on first browse.
  • New behavior:
    • scan path populates only the dedicated 200 px grid cache,
    • full-resolution RAM entries are admitted lazily on demand from user browsing.
  • Result: less cache thrash, fewer boomerang misses, and LRU order reflects actual user viewing patterns.

🧹 Removed / simplified settings

• Removed user-configurable “Cost per pixel” setting
  • Cache Settings tab no longer exposes this slider.
  • Value is no longer persisted/used.
  • RawCull now uses fixed 4 bytes/pixel (RGBA) for cache accounting.
  • Existing settings files remain compatible; legacy field is ignored.

📦 Dependency updates

• RsyncAnalyse → revision 8afefa6
• RsyncProcessStreaming → revision 70d6dc8

🔧 Internal changes (no direct user-visible UI change)

• SharedMemoryCache.costPerPixel is now a nonisolated let, reducing await hops on thumbnail hot paths.
• Removed dead/commented projected RAM diagnostic code in Cache Settings.

Summary:
