 # PaddlePaddle发行规范
 
-PaddlePaddle使用git-flow branching model做分支管理，使用[Semantic Versioning](http://semver.org/)标准表示PaddlePaddle版本号。
+PaddlePaddle使用Trunk Based Development，使用[Semantic Versioning](http://semver.org/)标准表示PaddlePaddle版本号。
 
 PaddlePaddle每次发新的版本，遵循以下流程:
 
 1. 从`develop`分支派生出新的分支，分支名为`release/版本号`。例如，`release/0.10.0`
-1. 将新分支的版本打上tag，tag为`版本号rc.Patch号`。第一个tag为`0.10.0rc1`，第二个为`0.10.0rc2`，依次类推。
-1. 对这个版本的提交，做如下几个操作:
-  * 使用Regression Test List作为检查列表，测试本次release的正确性。
-	  * 如果失败，记录下所有失败的例子，在这个`release/版本号`分支中，修复所有bug后，Patch号加一，到第二步
-	* 修改`python/setup.py.in`中的版本信息,并将`istaged`字段设为`True`。
-	* 将这个版本的python wheel包发布到pypi。
-	* 更新Docker镜像（参考后面的操作细节）。
-1. 第三步完成后，将`release/版本号`分支合入master分支，将master分支的合入commit打上tag，tag为`版本号`。同时再将`master`分支合入`develop`分支。
-1. 协同完成Release Note的书写。
+2. 将新分支的版本打上tag，tag为`版本号rc-Patch号`。例如，第一个tag为`0.10.0-rc0`。
+3. 新分支一般不接受新的feature和优化。QA在release分支上进行测试。研发基于最新的develop开发。
+4. QA和研发发现的bug，在develop上修复验证后，cherry-pick修复到release分支。直到release分支相对稳定。
+5. 如果有需要，在release分支最新代码上打上新的tag，比如`0.10.0-rc1`，让更多的用户加入测试。重复3-4步。
+6. release分支稳定后，打上正式的release tag，比如`0.10.0`。
+7. 将这个版本的python wheel包发布到pypi。
+8. 更新Docker镜像（参考后面的操作细节）。
 
 需要注意的是:
 
-* `release/版本号`分支一旦建立，一般不允许再从`develop`分支合入`release/版本号`。这样保证`release/版本号`分支功能的封闭，方便测试人员测试PaddlePaddle的行为。
-* 在`release/版本号`分支存在的时候，如果有bugfix的行为，需要将bugfix的分支同时merge到`master`, `develop`和`release/版本号`这三个分支。
+* bug修复需要先在develop上进行，然后进入release分支。而不是直接在release分支上开发。
+
+* release分支原则上只接受修复类的修改，不接受新feature。

 ## PaddlePaddle 分支规范
 
-PaddlePaddle开发过程使用[git-flow](http://nvie.com/posts/a-successful-git-branching-model/)分支规范，并适应github的特性做了一些区别。
-
-* PaddlePaddle的主版本库遵循[git-flow](http://nvie.com/posts/a-successful-git-branching-model/)分支规范。其中:
-	* `master`分支为稳定(stable branch)版本分支。每一个`master`分支的版本都是经过单元测试和回归测试的版本。
-	* `develop`分支为开发(develop branch)版本分支。每一个`develop`分支的版本都经过单元测试，但并没有经过回归测试。
-	* `release/版本号`分支为每一次Release时建立的临时分支。在这个阶段的代码正在经历回归测试。
+PaddlePaddle开发过程使用[Trunk Based Development](https://trunkbaseddevelopment.com/) 开发规范。
 
-* 其他用户的fork版本库并不需要严格遵守[git-flow](http://nvie.com/posts/a-successful-git-branching-model/)分支规范，但所有fork的版本库的所有分支都相当于特性分支。
-	* 建议，开发者fork的版本库使用`develop`分支同步主版本库的`develop`分支
-	* 建议，开发者fork的版本库中，再基于`develop`版本fork出自己的功能分支。
-	* 当功能分支开发完毕后，向PaddlePaddle的主版本库提交`Pull Reuqest`，进而进行代码评审。
-		* 在评审过程中，开发者修改自己的代码，可以继续在自己的功能分支提交代码。
+* `develop`分支为开发(develop branch)版本分支。每一个`develop`分支的版本都经过单元测试。并且会经过模型回归测试。
+* `release/版本号`分支为每一次Release时建立的临时分支。release分支主要用于测试，bug修复和最终发版。
+* `master`分支因为历史原因，已经废弃。
 
-* BugFix分支也是在开发者自己的fork版本库维护，与功能分支不同的是，BugFix分支需要分别给主版本库的`master`、`develop`与可能有的`release/版本号`分支，同时提起`Pull Request`。
+* 其他开发者fork的feature branch。
+	* 建议，开发者的feature branch需要同步主版本库的`develop`分支。
+	* 建议，开发者的feature branch需要基于主版本库中的`develop`分支。
+	* 当feature branch开发完毕后，向PaddlePaddle的主版本库提交`Pull Reuqest`，进而进行代码评审。
+		* 在评审过程中，开发者修改自己的代码，可以继续在自己的feature branch提交代码。

 Each time we release a new PaddlePaddle version, we should follow the below steps:
 
-1. Fork a new branch from `develop` named `release/[version]`, e.g. `release/0.10.0`.
-1. Push a new tag on the release branch, the tag name should be like `[version]rc.patch`. The
-   first tag should be `0.10.0rc1`, and the second should be `0.10.0.rc2` and so on.
-1. After that, we should do:
-  * Run all regression test on the Regression Test List (see PaddlePaddle TeamCity CI), to confirm
-      that this release has no major bugs.
-        * If regression test fails, we must fix those bugs and create a new `release/[version]`
-          branch from previous release branch.
-    * Modify `python/setup.py.in`, change the version number and change `ISTAGED` to `True`.
-    * Publish PaddlePaddle release wheel packages to pypi (see below instructions for detail).
-    * Update the Docker images (see below instructions for detail).
-1. After above step, merge `release/[version]` branch to master and push a tag on the master commit,
-   then merge `master` to `develop`.
-1. Update the Release Note.

-***NOTE:***
-
-* Do ***NOT*** merge commits from develop branch to release branches to keep the release branch contain
-  features only for current release, so that we can test on that version.
-* If we want to fix bugs on release branches, we must merge the fix to master, develop and release branch.
+1. Create a new release branch from `develop`，named `release/[version]`. E.g.，`release/0.10.0`
+2. Create a new tag for the release branch, tag format: `version-rc.Patch`. E.g. the first tag is `0.10.0-rc0`。
+3. New release branch normally doesn't accept new features or optimizations. QA will test on the release branch. Developer should develop based on `develop` branch.
+4. If QA or Developer find bugs. They should first fix and verify on `develop` branch. Then cherry-pick the fix to the release branch. Wait until the release branch is stable.
+5. If necessary, create a new tag on the relese branch, e.g. `0.10.0-rc1`. Involve more users to try it and repeat step 3-4.
+6. After release branch is stable，Create the official release tag，such as `0.10.0`.
+7. Release the python wheel package to pypi.
+8. Update the docker image (More details below).

+
+* bug fix should happen on `develop` branch, then cherry-pick to relese branch. Avoid developing directly on release branch.

 ## Branching Model
 
-We use [git-flow](http://nvie.com/posts/a-successful-git-branching-model/) as our branching model,
-with some modifications:
-
-* `master` branch is the stable branch. Each version on the master branch is tested and guaranteed.
-* `develop` branch is for development. Each commit on develop branch has passed CI unit test, but no
-  regression tests are run.
-* `release/[version]` branch is used to publish each release. Latest release version branches have
-  bugfix only for that version, but no feature updates.
-* Developer forks are not required to follow
-  [git-flow](http://nvie.com/posts/a-successful-git-branching-model/)
-  branching model, all forks is like a feature branch.
-    * Advise: developer fork's develop branch is used to sync up with main repo's develop branch.
-    * Advise: developer use it's fork's develop branch to for new branch to start developing.
-  * Use that branch on developer's fork to create pull requests and start reviews.
-      * developer can push new commits to that branch when the pull request is open.
-* Bug fixes are also started from developers forked repo. And, bug fixes branch can merge to
-  `master`, `develop` and `releases`.
+PaddlePaddle uses [Trunk Based Development](https://trunkbaseddevelopment.com/) as our branching model.
+
+* `develop` branch is used for development. Each comment to `develop` branc goes through unit tests and model regression tests.
+* `release/[version]` branch is used for each release. Release branch is used for tests, bug fix and evetual release.
+* `master` branch as been deprecated for historical reasons
+
+* Developer's feature branch。
+	* Developer's feature branch should sync with upstream `develop` branch.
+	* Developer's feature branch should be forked from upstream `develop` branch.
+	* After feature branch is ready, create a `Pull Request` against the Paddle repo and go through code review.
+	   * In the review process, develop modify codes and push to their own feature branch.
