+# Release Notes
+
+## 2.7.0
+
+Requirements: **Java 8+** required
+
+Please check [here](https://github.com/apache/incubator-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/incubator-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
+
+

+
+## Contributing to dubbo
+Dubbo is released under the non-restrictive Apache 2.0 license, and follows a very standard Github development process, using Github tracker for issues and merging pull requests into master. If you want to contribute even something trivial please do not hesitate, but follow the guidelines below.
+
+### Sign the Contributor License Agreement
+Before we accept a non-trivial patch or pull request we will need you to sign the Contributor License Agreement. Signing the contributor’s agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
+
+### Contact
+
+#### Mailing list
+
+The mailing list is the recommended way for discussing almost anything that related to Dubbo. Please refer to this [guide](https://github.com/apache/incubator-dubbo/wiki/Mailing-list-subscription-guide) for detailed documentation on how to subscribe.
+
+- [[email protected]](mailto:[email protected]): the develop mailing list, you can ask question here if you have encountered any problem when using or developing Dubbo.
+- [[email protected]](mailto:[email protected]): all the commits will be sent to this mailing list. You can subscribe to it if you are interested in Dubbo's development.
+- [[email protected]](mailto:[email protected]): all the Github [issue](https://github.com/apache/incubator-dubbo/issues) updates and [pull request](https://github.com/apache/incubator-dubbo/pulls) updates will be sent to this mailing list.
+
+### Reporting issue
+
+Please follow the [template](https://github.com/apache/incubator-dubbo/issues/new?template=dubbo-issue-report-template.md) for reporting any issues.
+
+### 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 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 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 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.
+
+* 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 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).
+
+### Contribution flow
+
+This is a rough outline of what a contributor's workflow looks like:
+
+* Fork the current repository
+* Create a topic branch from where to base the contribution. This is usually master.
+* Make commits of logical units.
+* Make sure 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/incubator-dubbo/blob/master/PULL_REQUEST_TEMPLATE.md)
+* Before you sending out the pull request, please sync your forked repository with remote repository, this will make your pull request simple and clear. See guide below:
+```
+git remote add upstream [email protected]:apache/incubator-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/incubator-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/incubator-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.
+
+**NOTICE**
+
+It is very important to set the dubbo_codestyle_for_idea.xml, otherwise you will fail to pass the Travis CI. Steps to set the code style are as below:
+
+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 ![manage profiles](codestyle/manage_profiles.png).
+From the drop-down list, select `Import Scheme`, then select this option `IntelliJ IDEA code style XML` to import scheme
+3. In the Scheme field, type the name of the new scheme and press ⏎ to save the changes.
+
