<li><ph><b>优化虚拟背景内存占用</b></ph>
<p>该版本升级了虚拟背景算法，降低了虚拟背景功能的内存占用。 相比之前的版本，在低端机上使用虚拟背景功能时 App 运行占用的内存降低了约 4%~10%（具体数值取决于设备型号和平台）。</p>
<li><ph><b>Optimize virtual background memory usage</b></ph><p>This version has upgraded the virtual background algorithm, reducing the memory usage of the virtual background feature. Compared to the previous version, the memory consumption of the app during the use of virtual background feature on low-end devices has been reduced by approximately 4% to 10% (specific values may vary depending on the device model and platform).</p>

<li props="cpp android"><ph><b>Screen sharing scenario optimization</b></ph><p props="cpp">This release optimizes the performance and encoding efficiency in ultra-high-definition (4K, 60 fps) game sharing scenarios, effectively reducing the system resource usage during screen sharing.</p>
<p props="android">This version optimizes the video encoding configuration in screen sharing scenarios. When users customize the <codeph>width</codeph> and <codeph>height</codeph> properties of the video, the SDK rounds down the actual encoding resolution while maintaining the aspect ratio of the video and the screen, ensuring that the final encoding resolution does not exceed the user-defined encoding resolution, thereby improving the accuracy of billing for screen sharing streams.</p>
