🚀 iPhoto v4.00 — MVVM Architecture & Advanced Editing

📸 MVVM architecture for smooth performance, color curves support, and cluster-based map browsing.

We're excited to announce iPhoto v4.00! 🎉
This major update brings a complete architectural transformation with MVVM design pattern, significantly reducing lag and improving system responsiveness. We've also added powerful color curve adjustments and cluster-based map navigation for a better photo management experience.

🌟 Key Updates in v4.00

🏗️ MVVM Architecture — Dramatically Improved Performance

Addressing user feedback: "Reduced lag and improved responsiveness"

  • Complete Architectural Refactoring: We have transformed the codebase to follow the Model-View-ViewModel (MVVM) design pattern.
  • Separation of Concerns: Clear separation between UI presentation, business logic, and data management layers.
  • Reactive UI Updates: The ViewModel efficiently manages state changes and automatically updates the View, eliminating unnecessary re-renders.
  • Reduced Operation Lag: Significantly lower UI freezing and lag during photo browsing, editing, and library management operations.
  • Enhanced System Fluency: Smooth scrolling, instant thumbnail loading, and responsive interactions even with large photo libraries.
  • Better Resource Management: Improved memory usage and CPU efficiency through proper data binding and lifecycle management.

    • Automatically groups nearby photos into clusters based on GPS coordinates
    • Dynamic cluster sizing adapts to zoom level and photo density
    • Visual cluster indicators show the number of photos in each location

  • Improved Navigation:

    • Zoom and pan to explore photo locations efficiently
    • Click on clusters to expand and view individual photos
    • Smooth transitions when navigating between clusters

    • Fast map interactions even with massive photo libraries
    • Reduced memory usage through intelligent cluster management

  • Enhanced User Experience:

    • Clear visualization of photo distribution across locations

    • Intuitive interaction with grouped photos on the map

🎯 Core Features (Carried Forward)

All beloved features from previous versions remain fully supported:

  • 🎥 Full Live Photo Support
    Automatically pairs HEIC/JPG + MOV files by content-ID or timestamp, with a "LIVE" badge and inline playback.

  • 🗂 Folder = Album
    Each folder becomes an album, managed by .iphoto.album.json (or .iphoto.album).

  • 🧠 Smart Albums
    Built-in "Library", "All Photos", "Videos", "Favorites", and "Recently Deleted" views.

  • 🖼 Immersive Detail Viewer
