+# PLDroidPlayer Release Notes for 1.3.0
+
+本次更新:
+
+## 版本
+
+1. 发布 pldroid-player-1.3.0.jar
+2. 更新 libpldroidplayer.so
+
+## 优化
+
+1. 优化直播累积延时
+2. 优化首开时间
+3. 优化播放器退出耗时较长
+
+## 功能
+
+1. 支持带 IP 地址的播放 URL，支持的格式为：protocol://ip/path?domain=xxxx.com
+   目前支持的协议为：RTMP、HDL，暂时不支持 HLS 协议
+2. 新增 PLNetworkManager 类，提供 DNS 缓存管理服务
+3. 新增 AVOptions 累积延时相关的配置参数
+4. 新增多种新的回调信息，方便更准确地感知播放过程中的状态变化
+
+## 缺陷 
+
+1. 修复动态构建 PLVideoTextureView 导致崩溃的问题
+2. 修复 onError 回调 extra 为 0 的情况
+3. 修复了部分码流的时长解析不准确的问题
+4. 修复点播缓冲过程中，断网操作导致长时间无法恢复的问题
+5. 修复特殊网络情况下，退出播放器时的 ANR 问题
+
+## 更新注意事项
+
+1. 如果需要使用 SDK 提供的 DNS 缓存管理服务，则需要添加如下配置
+
+```
+// 添加 happydns 的依赖
+dependencies {
+    compile 'com.qiniu:happy-dns:0.2.+'
+}
+
+// 添加网络状态监测的权限
+<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
+
+```
