-## 🧐 Why QuickView?
+## 🚀 Introduction
 
-Most image viewers today are either **bloated** (slow startup, huge size) or **outdated** (GDI rendering, poor high-DPI support).
+**QuickView** is currently one of the fastest image viewers available on the Windows platform. We focus purely on delivering the ultimate **viewing experience**—leave the heavy editing to professional tools like Photoshop. 
 
-**QuickView is different.** It is a ground-up rewrite using **Direct2D** and **Modern C++**, discarding legacy baggage. We integrate the industry's fastest decoding engines—**Google Wuffs, libjpeg-turbo, dav1d, libjxl**—to deliver:
+Rewritten from scratch using **Direct2D** and **C++23**, QuickView abandons legacy GDI rendering for a game-grade visual architecture. With a startup speed and rendering performance that rivals or exceeds closed-source commercial software, it is designed to handle everything from tiny icons to massive 8K RAW photos with zero latency.
 
-* **Instant Start:** Opens in milliseconds.
-* **60 FPS Rendering:** Silky smooth zooming and panning on 4K/8K monitors.
-* **Technical Transparency:** See the *real* data behind your images (Subsampling, Q-Factor).
+### 📂 Supported Formats
+QuickView supports almost all modern and professional image formats:
+
+* **Classic:** `JPG`, `JPEG`, `PNG`, `BMP`, `GIF`, `TIF`, `TIFF`, `ICO`
+* **Web/Modern:** `WEBP`, `AVIF`, `HEIC`, `HEIF`, `SVG`, `SVGZ`, `JXL`
+* **Pro/HDR:** `EXR`, `HDR`, `PIC`, `PSD`, `TGA`, `PCX`, `QOI`, `WBMP`, `PAM`, `PBM`, `PGM`, `PPM`, `WDP`, `HDP`
+* **RAW (LibRaw):** `ARW`, `CR2`, `CR3`, `DNG`, `NEF`, `ORF`, `RAF`, `RW2`, `SRW`, `X3F`, `MRW`, `MOS`, `KDC`, `DCR`, `SR2`, `PEF`, `ERF`, `3FR`, `MEF`, `NRW`, `RAW`

-## ✨ Features Showcase
+# QuickView v3.0.4 - The Quantum Flow Update
+**Release Date**: 2026-01-16
+
+### ⚡ Core Architecture: "Quantum Flow"
+- **Unified Scheduling & Decoding (Quantum Flow)**: Introduced a "Fast/Slow Dual-Channel" architecture (`FastLane` + `HeavyLanePool`) that isolates instant interactions from heavy decoding tasks.
+- **N+1 Hot-Spare Architecture**: Implemented a "Capped N+1" threading model where standby threads are kept warm for immediate response, maximizing CPU throughput without over-subscription.
+- **Deep Cancellation**: Granular "On-Demand" cancellation logic allowed for heavy formats (JXL/RAW/WebP), ensuring stale tasks (e.g., during rapid scrolling) are instantly terminated to save power.
+- **Direct D2D Passthrough**: Established a "Zero-Copy" pipeline where decoded `RawImageFrame` buffers are uploaded directly to GPU memory, bypassing GDI/GDI+ entirely.
+
+### 🎨 Visual & Rendering Refactor
+- **DirectComposition (Game-Grade Rendering)**: Completely abandoned the legacy SwapChain/GDI model in favor of a `DirectComposition` Visual tree.
+    - **Visual Ping-Pong**: Implemented a double-buffered Visual architecture for tear-free, artifact-free crossfades.
+    - **IDCompositionScaleTransform**: Hardware-accelerated high-precision zooming and panning.
+- **Native SVG Engine**: Replaced `nanosvg` with **Direct2D Native SVG** rendering.
+    - **Capabilities**: Supports complex SVG filters, gradients, and CSS transparency.
+    - **2-Stage Lossless Scaling**: Vector-based re-rasterization during deep zoom for infinite sharpness.
+    - *(Requirement: Windows 10 Creators Update 1703 or later)*.
+
+### 💾 Memory & Resource Management
+- **Arena Dynamic Allocation**: Switched to a **TripleArena** strategy using Polymorphic Memory Resources (PMR). Memory is pre-allocated and recycled (Bucket Strategy) to eliminate heap fragmentation.
+- **Smart Directional Prefetch**:
+    - **Auto-Tuning**: Automatically selects `Eco`, `Balanced`, or `Performance` prefetch strategies based on detected system RAM.
+    - **Manual Override**: Full user control over cache behavior.
+    - **Smart Skip**: Prevents "OOM" in Eco mode by intelligently skipping tasks that exceed the cache budget.
+
+### 🧩 Infrastructure & Metadata
+- **Metadata Architecture Refactor**: Decoupled "Fast Header Peeking" (for instant layout) from "Async Rich Metadata" parsing (Exif/IPTC/XMP), solving UI blocking issues.
+- **Debug HUD**: Added a real-time "Matrix" overlay (`F12`) visualizing the topology of the cache, worker lane status, and frame timings.
+
+---
+

+# QuickView v3.0.4 - 量子流更新 (The Quantum Flow Update)
+**发布日期**: 2026-01-16
+
+### ⚡ 核心架构："Quantum Flow"
+- **统一调度与解码 (Quantum Flow)**：引入了“快/慢双通道”架构 (`FastLane` + `HeavyLanePool`)，将即时交互与繁重的解码任务隔离。
+- **N+1 热备架构**：实现了“上限 N+1”线程模型，备用线程保持预热状态以立即响应，在不过度订阅的情况下最大化 CPU 吞吐量。
+- **深度取消 (Deep Cancellation)**：为重型格式 (JXL/RAW/WebP) 提供了细粒度的“按需”取消逻辑，确保过时的任务（例如在快速滚动期间）被立即终止以节省功耗。
+- **Direct D2D 直通**：建立了“零拷贝”管道，解码后的 `RawImageFrame` 缓冲区直接上传到 GPU 显存，完全绕过 GDI/GDI+。
+
+### 🎨 视觉与渲染重构
+- **DirectComposition (游戏级渲染)**：彻底放弃了传统的 SwapChain/GDI 模型，转而使用 `DirectComposition` 视觉树。
+    - **Visual Ping-Pong**：实现了双缓冲 Visual 架构，实现无撕裂、无伪影的交叉淡入淡出。
+    - **IDCompositionScaleTransform**：硬件加速的高精度缩放和平移。
+- **原生 SVG 引擎**：用 **Direct2D Native SVG** 渲染取代了 `nanosvg`。
+    - **能力**：支持复杂的 SVG 滤镜、渐变和 CSS 透明度。
+    - **2级无损缩放**：深度缩放期间进行基于矢量的重新光栅化，实现无限清晰度。
+    - *(要求：Windows 10 Creators Update 1703 或更高版本)*。
+
+### 💾 内存与资源管理
+- **Arena 动态分配 (智能内存)**：切换到使用多态内存资源 (PMR) 的 **TripleArena** 策略。内存被预先分配并循环使用 (Bucket Strategy)，彻底消除堆碎片。
+- **智能定向预读 (Smart Prefetch)**：
+    - **自动调优**：根据检测到的系统 RAM 自动选择 `Eco` (节能), `Balanced` (平衡), 或 `Performance` (性能) 预读策略。
+    - **手动覆盖**：用户可完全控制缓存行为。
+    - **智能跳过 (Smart Skip)**：在节能模式下，通过智能跳过超过缓存预算的任务来防止 "OOM" (内存溢出) 。
+
+### 🧩 基础设施与元数据
+- **元数据架构重构**：将“快速文件头窥视 (Fast Header Peeking)”（用于即时布局）与“异步富元数据 (Async Rich Metadata)”解析 (Exif/IPTC/XMP) 解耦，解决了 UI 阻塞问题。
+- **调试 HUD**：添加了实时“矩阵”叠加层 (`F12`)，可视化缓存拓扑、工作通道状态和帧时序。
+
