+**Performance Optimizations & Memory Management**
+
+This release focuses on workflow efficiency and backend stability improvements for ComfyUI users:
+
+**Frontend Performance Enhancements**
+- **Smart API Node Execution**: Fixed frontend behavior to prevent unnecessary re-execution of API nodes when inputs remain unchanged, significantly improving workflow performance for complex node graphs
+- **Updated Frontend Version**: Bumped to v1.20.7 with patch improvements for better user experience
+
+**Memory System Improvements**
+- **Enhanced Memory Estimation**: Memory estimation algorithms now properly account for conditioning data, providing more accurate memory usage predictions and preventing out-of-memory errors during complex workflows
+- **Better Resource Management**: Improved memory handling ensures smoother execution of resource-intensive workflows with multiple conditioning inputs
+
+These optimizations make ComfyUI more responsive and reliable, especially when working with large-scale workflows or resource-intensive models. The frontend improvements reduce unnecessary computational overhead, while the memory enhancements provide better stability for advanced AI generation tasks.

+**性能优化与内存管理**
+
+本次发布专注于改善ComfyUI用户的工作流效率和后端稳定性：
+
+**前端性能增强**
+- **智能API节点执行**: 修复了前端行为，防止在输入保持不变时不必要地重新执行API节点，显著提升复杂节点图的工作流性能
+- **前端版本更新**: 升级到v1.20.7，包含补丁改进，提供更好的用户体验
+
+**内存系统改进**
+- **增强内存估算**: 内存估算算法现在能够正确计算条件数据，提供更准确的内存使用预测，防止在复杂工作流中出现内存不足错误
+- **更好的资源管理**: 改进的内存处理确保包含多个条件输入的资源密集型工作流能够更顺畅地执行
+
+这些优化使ComfyUI更加响应迅速且可靠，特别是在处理大规模工作流或资源密集型模型时。前端改进减少了不必要的计算开销，而内存增强则为高级AI生成任务提供了更好的稳定性。
