Dubbo v2.7.1 Release Notes

Release Date: 2019-03-26 // about 5 years ago

  • ⚠ Warning: According to reports from the community, be aware of possible Service Discovery problems in certain circumstances. Check #4213 for details.
    风险提示：升级到2.7.1版本后，注册中心（多数是zookeeper）在某些特殊场景下会出现重复URL地址数据无法删除，导致消费方拿到的是失效地址，从而导致调用失败的问题，2.7.2版本里面会修复此问题，预计6月初发布。详细原因请参考#4213。

    🔔 Notice

    🚚 'zkclient' extension for 'org.apache.dubbo.remoting.zookeeper.ZookeeperTransporter' is removed from Dubbo 2.7.1, and 'curator' extension becomes the default extension. If you happen to config your application to use 'zkclient' explicitly, pls. switch to use 'curator' instead.
