+**Memory Optimization & Large Model Performance**
+
+This release focuses on critical memory optimizations for large model workflows, particularly improving performance with WAN 2.2 models and enhancing VRAM management for high-end systems:
+
+## WAN 2.2 Model Optimizations
+- **Reduced Memory Footprint**: Eliminated unnecessary memory clones in WAN 2.2 VAE operations, significantly reducing memory usage during image encoding/decoding workflows
+- **5B I2V Model Support**: Major memory optimization for WAN 2.2 5B image-to-video models, making these large-scale models more accessible for creators with limited VRAM
+
+## Enhanced VRAM Management
+- **Windows Large Card Support**: Added extra reserved VRAM allocation for high-end graphics cards on Windows, preventing system instability during intensive generation workflows
+- **Better Memory Allocation**: Improved memory management for users working with multiple large models simultaneously
+
+## Workflow Performance Benefits
+- **Faster VAE Processing**: WAN 2.2 VAE operations now run more efficiently with reduced memory overhead, enabling smoother image generation pipelines
+- **Stable Large Model Inference**: Enhanced stability when working with billion-parameter models, crucial for professional AI art creation and research workflows
+- **Improved Batch Processing**: Memory optimizations enable better handling of batch operations with large models
+
+These targeted optimizations make ComfyUI more reliable for professional workflows involving large-scale models, particularly benefiting creators working with cutting-edge image-to-video generation and high-resolution image processing tasks.

+**内存优化与大模型性能**
+
+本次发布专注于大模型工作流的关键内存优化，特别是改进了 WAN 2.2 模型的性能，并增强了高端显卡的 VRAM 管理：
+
+## WAN 2.2 模型优化
+- **减少内存占用**：去除了 WAN 2.2 VAE 操作中不必要的内存克隆，显著减少了图像编码/解码工作流中的内存使用
+- **5B I2V 模型支持**：对 WAN 2.2 5B 图像到视频模型进行内存优化，使这些模型对 VRAM 有限的创作者更加易用
+
+## 增强的 VRAM 管理
+- **Windows 大显卡支持**：为 Windows 上的高端显卡增加了额外的保留 VRAM 分配，防止在密集生成工作流中出现系统不稳定
+- **更好的内存分配**：改进了同时使用多个大模型的用户的内存管理
+
+## 工作流性能优势
+- **更快的 VAE 处理**：WAN 2.2 VAE 操作现在运行更高效，内存开销更少，实现更流畅的图像生成管道
+- **稳定的大模型推理**：增强了处理数十亿参数模型时的稳定性
+- **改进的批处理**：内存优化使大模型的批操作处理能力更强
+
+这些针对性优化使 ComfyUI 在涉及大体量模型的专业工作流中更加可靠。
