+# QNDroidRTC Release Notes for 6.1.0
+
+## 简介
+
+QNDroidRTC 是七牛推出的一款适用于 Android 平台的音视频通话 SDK，提供了包括美颜、滤镜、音视频通话等多种功能，提供灵活的接口，支持高度定制以及二次开发。
+
+## 版本
+
+- 发布 qndroid-rtc-6.1.0.jar
+- 更新 libqndroid_rtc.so
+
+## 优化
+
+- 优化弱网下的音频连麦体验
+
+## 缺陷
+
+- 修复特定场景下偶现的崩溃问题
+- 修复订阅统计信息失效的问题
+
+## 注意事项
+- 混音的使用姿势发生了改变，详情可参考[背景音乐混音](https://developer.qiniu.com/rtc/8771/background-music-mix-android)、[多音效混音](https://developer.qiniu.com/rtc/11965/android_audio_effect_mixing)、[音频裸数据混音](https://developer.qiniu.io/rtc/12581/android_audio_source_mixing)使用指南
+- libqnquic.so 用于优化弱网下的信令传输，为非必需依赖项
+- libqcrash.so 用于搜集 SDK 的崩溃信息，为非必需依赖项
+- 从 5.2.4 开始，org.webrtc 包被重命名为 org.qnwebrtc，请注意适配修改
