<p>这是SINGA的<a href="http://www.apache.org/dev/release-publishing.html">发布准备流程</a>指南。</p>
<ol>
<li><p>选择一个发布管理者。发布管理者（RM）是发布过程的协调者，他的签名文件（.asc）将会与发布一起上传。RM 生成 KEY (RSA 4096 位)并将其上传到公钥服务器，首先需要得到其他Apache用户对他的密钥的认可（签名），才能连接到信任网，RM需要先求助其他项目管理者帮忙认证他的密钥。<a href="http://www.apache.org/dev/release-signing.html">如何生成密钥？</a></p></li>
<li><p>检查license。 <a href="https://www.apache.org/legal/src-headers.html#faq-docs">FAQ</a>;
<a href="https://issues.apache.org/jira/projects/SINGA/issues/SINGA-447">SINGA Issue</a></p>
<ul>
<li>代码库不能包含与APL不兼容的第三方代码。</li>
<li>依赖项与APL兼容，GNU类license不兼容。</li>
<li>我们编写的所有源文件都必须包含Apache license头：<a href="http://www.apache.org/legal/src-headers.html">http://www.apache.org/legal/src-headers.html</a>.
链接中有一个脚本可以帮助将这个头同步到所有文件。</li>
<li>更新LICENSE文件。如果我们在发行包中包含了任何非APL的第三方代码，必须要在NOTICE文件的最后注明。</li>
</ul></li>
<li><p>复查版本。检查代码和文档。</p>
<ul>
<li>编译过程无错误。</li>
<li>(尽可能地)包含进单元测试。</li>
<li>Conda包运行无误。</li>
<li>Apache网站上的在线文档是最新的。</li>
</ul></li>
<li><p>准备好RELEASE_NOTES文件。包括以下项目，介绍，特性，错误（链接到JIRA或Github PR），变更，依赖列表，不兼容问题，可以按照这个<a href="(http://commons.apache.org/proper/commons-digester/commons-digester-3.0/RELEASE-NOTES.txt)">例子</a>来写。</p></li>
<li><p>打包候选版本。该版本应该打包成：apache-singa-VERSION.tar.gz。这个版本不应该包含任何二进制文件，包括git文件。但是CMake的编译依赖于git标签来获取版本号；要删除这个依赖，你需要手动更新CMakeLists.txt文件来设置版本号：</p>

<p>将软件包上传到<a href="https://dist.apache.org/repos/dist/dev/singa/">stage repo</a>。应包括tar文件、签名、KEY和SHA256校验和文件。MD5不再使用，详细规则在<a href="https://dist.apache.org/repos/dist/dev/singa/">这里</a>。阶段文件夹应该包括：</p>
