A quick rundown of the new features and documentation in the v1.3 release of Hyperledger Fabric:  
v1.3版本中新特性和文档的简要介绍:

# 新特性 (New features) #

*  [MSP Implementation with Identity Mixer][]: A way to keep identities anonymous and unlinkable through the use of zero-knowledge proofs. There is a tool that can generate Identity Mixer credentials in test environments known as idexmigen, the documentation for which can be found in [Identity Mixer MSP configuration generator (idemixgen)][Identity Mixer MSP configuration generator _idemixgen].  
    带有身份混淆器的MSP实现：一种通过使用零知识证明来保持身份匿名和不可链接的方法。这是个可以在名为idexmigen的测试环境中生成身份混淆凭证的工具，其文档可以在Identity Mixer MSP配置生成器(idemixgen)中找到。
 *  [Setting key-level endorsement policies][]: Allows the default chaincode-level endorsement policy to be overridden by a per-key endorsement policy.  
    设置键级背书策略：允许默认的链码级背书策略被每个键的背书策略覆盖。
 *  [Query the CouchDB State Database With Pagination][]: Clients can now page through result sets from chaincode queries, making it feasible to support large result sets with high performance.  
    使用分页查询CouchDB状态数据库：用户现在可以通过链接代码查询对结果集进行分页，从而可以高性能地支持大型结果集。
 *  [Chaincode for Developers][]: As an addition to the current Fabric support for chaincode written in Go and node.js, Java is now supported. You can find a javadoc for this here.  
    用于开发人员的链代码：作为当前Fabric支出用Go和node.js编写链代码的补充。现在支持Java了。你可以在这里找到javadoc。
 *  [Peer channel-based event services][]: The peer channel-based event service itself is not new (it first debuted in v1.1), but the v1.3 release marks the end of the old event hub. Applications using the old event hub must switch over to the new peer channel-based event service prior to upgrading to v1.3.  
    基于通道事件服务：基于通道事件服务本身并不是新的(它首次出现在v1.1中)，但是v1.3版本标志着旧事件中心的结束。在升级到v1.3之前，使用旧事件中心的应用程序必须切换到新的基于通道的事件服务。

# 新教程 (New tutorials) #

[Upgrading to the Newest Version of Fabric][]: Leverages the BYFN network to show how an upgrade flow should work. Includes both a script (which can serve as a template for upgrades), as well as the individual commands.  
升级到最新版本的Fabric：利用BYFN网络显示升级流程应该如何工作。包括脚本(它可以作为升级的模板)和单个命令。

[Query the CouchDB State Database With Pagination][]: Expands the current CouchDB tutorial to add pagination.  
使用分页查询CouchDB状态数据库：扩展当前的CouchDB教程以添加分页功能。

# 其他新文档 (Other new documentation) #

[Blockchain network][]: Conceptual documentation that shows how the parts of a network interact with each other. The initial version of this document was added in v1.2.  
区块链网络：展示网络各部分如何相互交互的概念文档。这个文档的最初版本是在v1.2添加的。

# 发布说明 (Release notes) #
