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.
