Important notes

Please note the following incompatibilities or caveats, but don't worry, this release has no impact on core RPC process. You can avoid all the potential impacts by simply adding dependencies or following configuration rules.

• If you are using AccesslogFilter, Telnet or Mock, remember add fastjson as a thirdpart dependency.
• If you are already using annotation config, we strongly recommend you upgrade to 2.5.7, in which verion we have changed the way annotation is used, and also changed the implementation.
• If check = true and registry can not be connected at start phase, the project can still be successfully started by degrading to use the registry cache.
• Current version will discard the monitor statistics when MonitorService is not ready yet。
