-## Checklist
-- [x] Make sure there is a [GitHub_issue](https://github.com/apache/dubbo/issues) field for the change (usually before you start working on it). Trivial changes like typos do not require a GitHub issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
-- [ ] Each commit in the pull request should have a meaningful subject line and body.
-- [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
-- [ ] Check if is necessary to patch to Dubbo 3 if you are work on Dubbo 2.7
-- [ ] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add sample in [dubbo samples](https://github.com/apache/dubbo-samples) project.
-- [ ] Add some description to [dubbo-website](https://github.com/apache/dubbo-website) project if you are requesting to add a feature.
-- [ ] GitHub Actions works fine on your own branch.
-- [ ] If this contribution is large, please follow the [Software Donation Guide](https://github.com/apache/dubbo/wiki/Software-donation-guide).

-## 2.7.0
-
-Requirements: **Java 8+** required
-
-Please check [here](https://github.com/apache/dubbo/blob/2.7.0-release/CHANGES.md#upgrading-and-compatibility-notifications) for notes and possible compatibility issues for upgrading from 2.6.x or lower to 2.7.0.
-
-### New Features
-
-- Enhancement of service governance rules.
-  - Enriched Routing Rules.
-    1. Conditional Routing. Supports both application-level and service-level conditions.
-    2. Tag Routing. Newly introduced to better support traffic isolation, such as grey deployment.
-  - Decoupling governance rules with the registry, making it easier to extend. Apollo and Zookeeper are available in this version. Nacos support is on the way...
-  - Application-level Dynamic Configuration support.
-  - Use YAML as the configuration language, which is more friendly to read and use.
-
-- Externalized Configuration. Supports reading `dubbo.properties` hosted in remote centralized configuration center - centralized configuration.
-
-- Simplified registry URL. With lower Registry memory use and less notification pressure from Service Directory, separates Configuration notification from Service Discovery.
-
-- Metadata Center. A totally new concept since 2.7.0,  used to store service metadata including static configuration, service definition, method signature, etc.. By default, Zookeeper and Redis are supported as the backend storage. Will work as the basis of service testing, mock and other service governance features going to be supported in [Dubbo-Admin](https://github.com/apache/dubbo-admin).
-
-- Asynchronous Programming Model (only works for Dubbo protocol now)
-  - Built-in support for the method with CompletableFuture<T> signature.
-  - Server-side asynchronous support, with an AsyncContext API works like Servlet 3.0.
-  - Asynchronous filter chain callback.
-
-- Serialization Extension: Protobuf.
-
-- Caching Policy Extension: Expiring Cache.
-
-### Enhancements / Bugfixes
-
-- Load Balancing strategy enhancement: ConsitentHash #2190, LeastActive #2171, Random #2597, RoundRobin #2650.
-
-- Third-party dependency upgrading.
-  - Switch default remoting to Netty 4.
-  - Switch default Zookeeper client to Curator.
-  - Upgrade Jetty to 9.x.
-
-- IPV6 support #2079.
-
-- Performance tuning, check hanging requests on a closed channel, make them return directly #2185.
-
-- Fixed the serialization problem of JDK primitive types in Kryo #2178.
-
-- Fixed the problem of failing to notify Consumer as early as possible after the Provider side deserialization failed #1903.
-
-### Upgrading and Compatibility Notifications
-
-We have always keep compatibility in mind during the whole process of 2.7.0. We even want old users to upgrade with only on pom version upgrade, but it's hard to achieve that, especially when considering that we have the package renamed in this version, so we had some tradeoffs. If you only used the Dubbo's most basic features, you may have little problems of upgrading, but if you have used some advanced features or have some SPI extensions inside, you'd better read the upgrade notifications carefully. The compatibility issues can be classified into the following 5 categories, for each part, there will have detailed dos and don'ts published later in the official website.
-
-1. Interoperability between 2.7.0 and lower versions
-
-2. Package renaming
-
-   com.alibaba.dubbo -> org.apache.dubbo
-
-3. Simplification of registered URLs
-
-4. Service Governance Rules
-
-5. Configuration
-

 ### Code Conventions
-Our code style is almost in line with the standard java conventions (Popular IDE's default setting satisfy this), with the following additional restricts:  
-* If there are more than 120 characters in the current line, begin a new line.
+Our code style is almost in line with the standard java conventions(Popular IDE's default setting satisfy this), only changed the following two restricts:  
+1. Classes under 'com.alibaba.*' and 'com.taobao.*' package are grouped separately, and put on top of all other 'imports'.  
+2. If there are more than 120 characters in current line, start a new line.
 
-* Make sure all new .java files to have a simple Javadoc class comment with at least a @date tag identifying birth, and preferably at least a paragraph on the intended purpose of the class.
+We provide a template file [dubbo_codestyle_for_idea.xml](https://github.com/alibaba/dubbo/tree/master/codestyle/dubbo_codestyle_for_idea.xml) for IntelliJ idea, you can import it to you IDE. If you use Eclipse you can config manually by referencing the same file.  
+
+* Make sure all new .java files to have a simple Javadoc class comment with at least a @date tag identifying birth, and preferably at least a paragraph on what the class is for.
 
 * Add the ASF license header comment to all new .java files (copy from existing files in the project)
 
-* Make sure no @author tag gets appended to the file you contribute to as the @author tag is incompatible with Apache. Rest assured, other ways, including CVS, will ensure transparency, fairness in recording your contributions. 
+* Make sure no @author tag added to the file you contribute since @author tag is not used at Apache, other ways such as cvs will record all your contributions fairly.
 
 * Add some Javadocs and, if you change the namespace, some XSD doc elements.
 
-* Sufficient unit-tests should accompany new feature development or non-trivial bug fixes. 
+* A few unit tests should be added for a new feature or an important bugfix.
 
-* If no-one else is using your branch, please rebase it against the current master (or another target branch in the main project).
-
-* When writing a commit message, please follow the following conventions: should your commit address an open issue, please add Fixes #XXX at the end of the commit message (where XXX is the issue number).
-
-### Contribution flow
-
-A rough outline of an ideal contributors' workflow is as follows:
-
-* Fork the current repository
-* Create a topic branch from where to base the contribution. Mostly, it's the master branch.
-* Make commits of logical units.
-* Make sure the commit messages are in the proper format (see below).
-* Push changes in a topic branch to your forked repository.
-* Follow the checklist in the [pull request template](https://github.com/apache/dubbo/blob/master/PULL_REQUEST_TEMPLATE.md)
-* Before sending out the pull request, please sync your forked repository with the remote repository to ensure that your PR is elegant, concise. Reference the guide below:
-```
-git remote add upstream git@github.com:apache/dubbo.git
-git fetch upstream
-git rebase upstream/master
-git checkout -b your_awesome_patch
-... add some work
-git push origin your_awesome_patch
-```
-* Submit a pull request to apache/dubbo and wait for the reply.
-
-Thanks for contributing!
-
-### Code style
-
-We provide a template file [dubbo_codestyle_for_idea.xml](https://github.com/apache/dubbo/tree/master/codestyle/dubbo_codestyle_for_idea.xml) for IntelliJ idea that you can import it to your workplace. 
-If you use Eclipse, you can use the IntelliJ Idea template for manually configuring your file.
-
-**NOTICE**
-
-It's critical to set the dubbo_codestyle_for_idea.xml to avoid the failure of your Travis CI builds. Steps to configure the code styles are as follows:
-
-1. Enter `Editor > Code Style`
-2. To manage a code style scheme, in the Code Style page, select the desired scheme from the drop-down list, and click on ![manage profiles](codestyle/manage_profiles.png).
-From the drop-down list, select `Import Scheme`, then choose the option `IntelliJ IDEA code style XML` to import the scheme. 
-3. In the Scheme field, type the name of the new scheme and press ⏎ to save the changes.
+* If no-one else is using your branch, please rebase it against the current master (or other target branch in the main project).
 
+* When writing a commit message please follow these conventions, if you are fixing an existing issue please add Fixes #XXX at the end of the commit message (where XXX is the issue number).

-
-```bash
-git clone https://github.com/apache/dubbo-samples.git
-cd dubbo-samples/1-basic/dubbo-samples-api
-```
-
-There's a [README](https://github.com/apache/dubbo-samples/blob/389cd612f1ea57ee6e575005b32f195c442c35a2/1-basic/dubbo-samples-api/README.md) file under `dubbo-samples-api` directory. We recommend referencing the samples in that directory by following the below-mentioned instructions:
-
-### Maven dependency

-
-### Implement service interface for the provider
-
-```java
-package org.apache.dubbo.samples.provider;
-
-import org.apache.dubbo.samples.api.GreetingsService;
-
-public class GreetingsServiceImpl implements GreetingsService {
-    @Override
-    public String sayHi(String name) {
-        return "hi, " + name;
-    }
-}
-```
-
-*See [provider/GreetingsServiceImpl.java](https://github.com/apache/dubbo-samples/blob/389cd612f1ea57ee6e575005b32f195c442c35a2/1-basic/dubbo-samples-api/src/main/java/org/apache/dubbo/samples/provider/GreetingsServiceImpl.java) on GitHub.*

-package org.apache.dubbo.samples.provider;
-
-
-import org.apache.dubbo.config.ApplicationConfig;
-import org.apache.dubbo.config.RegistryConfig;
-import org.apache.dubbo.config.ServiceConfig;
-import org.apache.dubbo.samples.api.GreetingsService;
-
-import java.util.concurrent.CountDownLatch;
-
-public class Application {
-    private static String zookeeperHost = System.getProperty("zookeeper.address", "127.0.0.1");
-
-    public static void main(String[] args) throws Exception {
-        ServiceConfig<GreetingsService> service = new ServiceConfig<>();
-        service.setApplication(new ApplicationConfig("first-dubbo-provider"));
-        service.setRegistry(new RegistryConfig("zookeeper://" + zookeeperHost + ":2181"));
-        service.setInterface(GreetingsService.class);
-        service.setRef(new GreetingsServiceImpl());
-        service.export();
-
-        System.out.println("dubbo service started");
-        new CountDownLatch(1).await();
-    }
-}
-```
-
-*See [provider/Application.java](https://github.com/apache/dubbo-samples/blob/389cd612f1ea57ee6e575005b32f195c442c35a2/1-basic/dubbo-samples-spring-xml/src/main/java/org/apache/dubbo/samples/provider/Application.java) on GitHub.*
-
-### Build and run the provider
-
-```bash
-mvn clean package
-mvn -Djava.net.preferIPv4Stack=true -Dexec.mainClass=org.apache.dubbo.samples.provider.Application exec:java
-```
-

-
-```java
-package org.apache.dubbo.samples.client;
-
-
-import org.apache.dubbo.config.ApplicationConfig;
-import org.apache.dubbo.config.ReferenceConfig;
-import org.apache.dubbo.config.RegistryConfig;

-        reference.setApplication(new ApplicationConfig("first-dubbo-consumer"));
-        reference.setRegistry(new RegistryConfig("zookeeper://" + zookeeperHost + ":2181"));
-        reference.setInterface(GreetingsService.class);
-        GreetingsService service = reference.get();
-        String message = service.sayHi("dubbo");
-        System.out.println(message);
-    }
-}
-```
-*See [client/Application.java](https://github.com/apache/dubbo-samples/blob/389cd612f1ea57ee6e575005b32f195c442c35a2/1-basic/dubbo-samples-api/src/main/java/org/apache/dubbo/samples/client/Application.java) on GitHub.*
-
-### Build and run the consumer
-
-```bash
-mvn clean package
-mvn -Djava.net.preferIPv4Stack=true -Dexec.mainClass=org.apache.dubbo.samples.client.Application exec:java
-```
-
-The consumer will print out `hi, dubbo` on the screen.
-
-
-### Next steps

-
-```
-  mvn clean install
-```
-
-## Recommended Test Environment
-To avoid intermittent test failures (i.e., flaky tests), it is recommended to have a machine or virtual machine with the following specifications:
-
-* Minimum of 2CPUs.
-* Minimum of 2Gb of RAM.
-
-### How does the Dubbo Community collaborate?
-
-The Dubbo Community primarily communicates on GitHub through issues, discussions, and pull requests.
-
-- Issues: We use issues to track bugs and tasks. Any **work-related** item is associated with an issue.
-- Discussions: We use discussions for questions, early proposals, and announcements. Any **idea-related** item is associated with a discussion.
-- Pull Requests: We use pull requests to merge a set of changes from contributors into Dubbo.
-
-We have also implemented [a project board](https://github.com/orgs/apache/projects/337) to monitor all the items.
-
-Any essential changes should be discussed on the mailing list before they happen.
-
-### Seeking for help

-## Reporting a Vulnerability
-
-The Apache Software Foundation takes a rigorous standpoint in annihilating the security issues in its software projects. Apache Dubbo is highly sensitive and forthcoming to issues pertaining to its features and functionality.
-
-If you have apprehensions regarding Dubbo's security or you discover vulnerability or potential threat, don’t hesitate to get in touch with the Apache Dubbo Security Team by dropping a mail at security@dubbo.apache.org. In the email, specify the description of the issue or potential threat. You are also urged to recommend the way to reproduce and replicate the issue. The Dubbo community will get back to you after assessing and analysing the findings.
-
-PLEASE PAY ATTENTION to report the security issue on the security email before disclosing it on public domain.
-
-## Vulnerability Handling
-
-An overview of the vulnerability handling process is:
-
-* The reporter reports the vulnerability privately to Apache.
-* The appropriate project's security team works privately with the reporter to resolve the vulnerability.
-* A new release of the Apache product concerned is made that includes the fix.
-* The vulnerability is publicly announced.
-
-A more detailed description of the process can be found [here](https://www.apache.org/security/committers.html).
