| ## 2.7.0 | ||
| 环境要求：需要Java 8及以上版本支持 | ||
|
|
||
| 请在[这里]()了解关于升级2.7.x版本的注意事项和兼容性问题 | ||
|
|
||
| ## New Features | ||
|
|
||
| - 服务治理规则增强。 | ||
| - 更丰富的服务治理规则，新增应用级别条件路由、Tag路由等 | ||
| - 治理规则与注册中心解耦，增加对Apollo等第三方专业配置中心的支持，更易于扩展 | ||
| - 新增应用级别的动态配置规则 | ||
| - 规则体使用更易读、易用YAML格式 | ||
|
|
||
| - 外部化配置。支持读取托管在远程的集中式配置中心的dubbo.properties，实现应用配置的集中式管控。 | ||
|
|
||
| - 更精炼的注册中心URL，进一步减轻注册中心存储和同步压力，初步实现地址和配置的职责分离。 | ||
|
|
||
| - 新增服务元数据中心，负责存储包括服务静态化配置、服务定义（如方法签名）等数据，默认提供Zookeeper, Redis支持。此功能也是OPS实现服务测试、Mock等治理能力的基础。 | ||
|
|
||
| - 异步编程模式增强（限定于Dubbo协议） | ||
| - 原生CompletableFuture<T>签名接口支持 | ||
| - 服务端异步支持 | ||
| - 异步Filter链 | ||
|
|
||
| - 新增Protobuf序列化协议扩展 | ||
|
|
||
| - 新增ExpiringCache缓存策略扩展 | ||
|
|
||
| ## Enhancements / Bugfixes | ||
|
|
||
| - 负载均衡策略优化，包括ConsitentHash(#2190) 、LeastActive(#2171)、Random(#2597) 、RoundRobin(#2586) (#2650) | ||
|
|
||
| - 升级第三方依赖：默认通信框架为netty 4、默认ZK客户端为Curator、Jetty 9k | ||
|
|
||
| - 增加地址读取时对IPV6的支持(#2079) | ||
|
|
||
| - 性能优化，链接关闭的情况下使得Consumer快速返回 (#2185) | ||
|
|
||
| - 修复Jdk原生类型在kryo中的序列化问题 (#2178) | ||
|
|
||
| - 修复Provider端反序列化失败后，没有及早通知Consumer端的问题 (#1903) | ||
|
|
||
|
|
||
| ## 升级与兼容性 | ||
|
|
||
| 此次版本发布我们遵循了保持和老版本兼容的原则，尤其是在一些可能会破坏2.7版本与低版本互操作性的问题上，我们增加了一些兼容性代码，典型如服务治理规则、Package重命名、注册URL简化等。 | ||
|
|
||
| 1. Package重命名 | ||
|
|
||
| com.alibaba.dubbo -> org.apache.dubbo | ||
|
|
||
| 2. 注册URL简化 | ||
|
|
||
| 3. 服务治理规则 | ||
|
|
||
| 4. 配置 | ||
