Office 365 专业增强版的更新通道概述Overview of update channels for Office 365 ProPlus
Office 365 专业增强版的好处之一是，Microsoft 可以通过每月更新定期提供 Office 应用的新功能。不过，作为向组织中的用户部署 Office 365 专业增强版的管理员，可能需要更好地控制用户获取这些新功能的频率。Microsoft 提供了三种选项（称为“更新通道”），以便于控制多久更新一次 Office 365 专业增强版的新功能。下面概述了这三个选项。One of the benefits of Office 365 ProPlus is that Microsoft can provide new features for Office apps on a regular basis, through monthly updates. However, as the admin who deploys Office 365 ProPlus to the users in your organization, you might want to have more control over how often your users get these new features. Microsoft provides you three options, called update channels, to control how often Office 365 ProPlus is updated with new features. Here's an overview of the three options.
|更新通道Update channel||主要用途Primary purpose||多久更新一次新功能How often updated with new features||下列产品的默认更新通道Default update channel for the following products|
||最新 Office 功能一经推出，便立即提供给用户。Provide users with the newest features of Office as soon as they're available.
||Visio Online 计划 2（以前称为 Visio Pro for Office 365）Visio Online Plan 2 (previously named Visio Pro for Office 365)
Project Online 桌面客户端Project Online Desktop Client
Office 365 商业版，即随附一些 Office 365 计划的 Office 版本（如企业高级版）。Office 365 Business, which is the version of Office that comes with some Office 365 plans, such as Business Premium.
||一年仅向用户提供几次 Office 新功能。Provide users with new features of Office only a few times a year.
||半年一次（1 月和 7 月）Every six months, in January and July
||Office 365 专业增强版Office 365 ProPlus
|半年频道（定向）Semi-Annual Channel (Targeted)
||让试点用户和应用兼容性测试人员有机会测试下一个半年频道。Provide pilot users and application compatibility testers the opportunity to test the next Semi-Annual Channel.
||半年一次（3 月和 9 月）Every six months, in March and September
2017 年 9 月前，这些更新通道分别称为“当前频道”、“延期频道”和“延期频道的首次发布”。Prior to September 2017, these update channels were named Current Channel, Deferred Channel, and First Release for Deferred Channel.
若要决定向用户部署哪个更新通道，具体视多个因素而定，其中包括每当 Office 365 专业增强版有更新版本时需要测试多少个业务线应用、加载项或宏。为了有助于做出这样的决定，请查看下面关于 Office 365 专业增强版适用的三个更新通道的介绍。Which update channel you decide to deploy to your users depends on several factors, including how many line-of-business applications, add-ins, or macros that you need to test any time there is an updated version of Office 365 ProPlus. To help you make this decision, review the following information about the three update channels that are available for Office 365 ProPlus.
Office 365 专业增强版的每月频道Monthly Channel for Office 365 ProPlus
在下列情况下，每月频道可能是组织的理想之选：Monthly Channel might be the right choice for your organization in the following situations:
要在最新 Office 功能一推出就立即提供给用户You want to provide your users with the newest features of Office as soon as those features are available
不需要测试很多业务线应用、加载项或宏来确定它们是否与 Office 的更新版本兼容。You don't have many line-of-business applications, add-ins, or macros that you need to test to determine if they work with an updated version of Office.
包含新功能的每月频道应为每月发布一次，尽管功能发布时间没有既定的计划。除了新功能或更新功能以外，发布内容可能还包含与安全无关的更新程序，如旨在提升 Office 稳定性或性能的更新程序。每月频道的安全更新程序通常于每月的第二个星期二发布。如果在其他任何时间有与安全无关的严重问题需要修复，我们将发布单独的每月频道来修复相应问题。A Monthly Channel with new features is expected to be released each month, although there is no set schedule for when a feature release occurs. In addition to new or updated features, the release might also contain non-security updates, such as updates that provide stability or performance improvements for Office. Security updates for Monthly Channel are usually released on the second Tuesday of the month. At any other time, if there is a critical non-security issue that needs to be fixed, we will provide a separate Monthly Channel release that fixes the issue.
所发布的每月频道具有累积性。最新发布的每月频道包含之前发布的每月频道的所有功能、安全更新程序以及与安全无关的更新程序。Monthly Channel releases are cumulative. The most current Monthly Channel release contains all the features, security updates, and non-security updates from the previous Monthly Channel releases.
发布的每月频道的支持期到下一个每月频道发布时就结束了。不会为之前发布的每月频道提供新安全更新程序。A Monthly Channel release is supported only until the next Monthly Channel release is available. No new security updates are provided for previous Monthly Channel releases.
还有一个通道是每月频道（定向）。使用此更新通道，可以提前了解即将发布的每月频道。这是受支持的更新通道，通常在包含新功能的每月频道发布前至少提前一周发布。There is also Monthly Channel (Targeted). This update channel provides an early look at the upcoming Monthly Channel release. It is a supported update channel, and usually is available at least one week ahead of time when it's a Monthly Channel release that contains new features.
Office 365 专业增强版的半年频道Semi-Annual Channel for Office 365 ProPlus
如果组织不希望立即部署最新 Office 功能，或需要测试大量业务线应用、加载项或宏是否与 Office 兼容，那么半年频道可能更适合组织。这是因为一年只需向半年频道添加两次新功能，而不是每月添加一次。半年频道是 Office 365 专业增强版的默认更新通道。If your organization doesn't want to deploy the latest features of Office right away or you have a significant number of line-of-business applications, add-ins, or macros that you need to test with Office, then Semi-Annual Channel might be the better choice for your organization. That's because new features are added to Semi-Annual Channel only twice a year, instead of every month. Semi-Annual Channel is the default update channel for Office 365 ProPlus.
包含新功能的半年频道应为一年发布两次（1 月和 7 月）。在其他任何时间，都不会向半年频道添加新功能。半年频道中的功能是之前在每月频道中发布过的功能。A Semi-Annual Channel with new features is expected to be released twice a year, in January and July. New features aren't added to Semi-Annual Channel at any other time. The features that are included in Semi-Annual Channel are features that have been released previously in Monthly Channel.
Microsoft 在半年频道新功能发布前提前 4 个月，提供即将发布的半年频道的内部版本，以便组织内的试点用户和应用程序兼容性测试人员可以使用即将发布的半年频道。这些内部版本是通过半年频道（定向）更新通道，提供下一个包含新功能的半年频道版本中的相同特性和功能。In the four months prior to a new Semi-Annual Channel feature release, Microsoft provides builds of the upcoming release so that pilot users and application compatibility testers in your organization can work with the upcoming release. These builds are provided through the Semi-Annual Channel (Targeted) update channel and provide the same features and functionality that will be in the next release of Semi-Annual Channel that includes new features.
After the January and July releases of Semi-Annual Channel, additional security updates, if needed, can also be added to Semi-Annual Channel.After the January and July releases of Semi-Annual Channel, additional security updates, if needed, can also be added to Semi-Annual Channel. A release of Semi-Annual Channel with these updates usually occurs on the second Tuesday of the month.A release of Semi-Annual Channel with these updates usually occurs on the second Tuesday of the month. If there is a critical non-security issue that needs to be fixed in Semi-Annual Channel, that non-security update will also be included in a Semi-Annual Channel release, usually on the second Tuesday of the month.If there is a critical non-security issue that needs to be fixed in Semi-Annual Channel, that non-security update will also be included in a Semi-Annual Channel release, usually on the second Tuesday of the month.
Office 365 专业增强版的半年频道（定向）Semi-Annual Channel (Targeted) for Office 365 ProPlus
为了帮助组织做好接收半年频道发布的准备，Microsoft 提供了半年频道（定向）。此更新通道的主要目的是，让组织内的试点用户和应用程序兼容性测试人员有机会使用即将发布的半年频道。在此期间（约四个月），可能会发现业务线应用程序、加载项或宏需要修复的潜在问题，或要让 Microsoft 修复的潜在问题。半年频道（定向）版本提供下一个包含新功能的半年频道版本中的相同特性和功能。To help your organization prepare for a Semi-Annual Channel release, Microsoft provides Semi-Annual Channel (Targeted). The primary purpose of this update channel is to give pilot users and application compatibility testers in your organization a chance to work with the upcoming Semi-Annual Channel release. During this time, which is about four months, you might identify possible issues that you need to fix with your line-of-business applications, add-ins, or macros or that you want Microsoft to fix. Semi-Annual Channel (Targeted) releases provide the same features and functionality that will be in the next release of Semi-Annual Channel that includes new features.
包含新功能的半年频道（定向）应为一年发布两次（3 月和 9 月）。在其他任何时间，都不会向半年频道（定向）添加新功能。半年频道（定向）中的功能是之前在每月频道中发布过的功能。A Semi-Annual Channel (Targeted) with new features is expected to be released twice a year, in March and September. New features aren't added to Semi-Annual Channel (Targeted) at any other time. The features that are included in Semi-Annual Channel (Targeted) are features that have been released previously in Monthly Channel.
3 月和 9 月发布的半年频道（定向）还包含之前在每月频道中发布过的安全更新程序和与安全无关的更新程序。在 3 月和 9 月发布半年频道（定向）后，如有必要，还可以向半年频道（定向）添加其他安全更新程序和与安全无关的更新程序。包含这些更新程序的半年频道（定向）通常在当月的第二个星期二发布。The March and September feature releases for Semi-Annual Channel (Targeted) also include security and non-security updates that have been released previously in Monthly Channel. After the March and September releases, additional security and non-security updates, if needed, can also be added to Semi-Annual Channel (Targeted). A release of Semi-Annual Channel (Targeted) with these updates usually occurs on the second Tuesday of the month.
尽管此更新通道主要设计用于测试，但它仍是 Office 365 专业增强版的完全受支持版本。Even though this update channel is primarily designed for your testing, it's a fully supported version of Office 365 ProPlus.

通常在当月的第二个星期二发布安全更新（如果需要）。针对半年频道和半年频道（定向）的与安全无关的更新程序通常也在当月的第二个星期二发布（如果需要）。Security updates, if needed, are usually released on the second Tuesday of the month. Non-security updates, if needed, for Semi-Annual Channel and Semi-Annual Channel (Targeted) also are usually released on the second Tuesday of the month.
Office 365 专业增强版的半年频道功能的支持期Support duration for semi-annual feature releases for Office 365 ProPlus
Office 365 专业增强版的半年频道功能更新的支持期为 18 个月（从首次发布开始算起）。The semi-annual feature update releases of Office 365 ProPlus are supported for 18 months, starting from the initial release.
包含功能更新的新版本于 3 月和 9 月发布到半年频道（定向）。4 个月后（即在 7 月和 1 月），包含这些功能更新的版本发布到半年频道，并在之后的 14 个月内受支持。A new version, with feature updates, will be released to Semi-Annual Channel (Targeted) in March and September. Four months later, in July and January, that version, with those feature updates, will be released to Semi-Annual Channel and will be supported for the next 14 months.
例如，2018 年 9 月 11 日，Office 365 专业增强版 1808 版本发布到半年频道（定向）。版本 1808 预计将于 2019 年 1 月 8 日发布到半年频道，并在 2020 年 3 月前一直在半年频道中受支持。2019 年 3 月，包含新功能的新版 Office 365 专业增强版将发布到半年频道（定向）。此版本预计将于 2019 年 7 月发布到半年频道，并在 2020 年 9 月前一直在半年频道中受支持。For example, on September 11, 2018, Version 1808 of Office 365 ProPlus was released to Semi-Annual Channel (Targeted). On January 8, 2019, Version 1808 is scheduled to be made available to Semi-Annual Channel and will be supported in Semi-Annual Channel until March 2020. In March 2019, a new version of Office 365 ProPlus with new features will be released to Semi-Annual Channel (Targeted). That version is scheduled to be made available to Semi-Annual Channel in July 2019, and will be supported in Semi-Annual Channel until September 2020.
借助这样的支持期，IT 专业人员可以有更宽裕的时间来灵活部署版本。例如，可以满足希望一年更新一次的客户的需求。始终都会有多个受支持版本的半年频道。不过，请注意，对于半年频道（定向），只支持最新发布的版本。This support duration provides more time and flexibility for IT Pros to deploy releases. For example, customers who want to update once a year will be able to do so. There will always be more than one supported version of Semi-Annual Channel available. Note, however, that only the most current release of Semi-Annual Channel (Targeted) is supported.
Windows 10 也计划于 3 月和 9 月这两个目标期限发布 Windows 10 功能更新。这些发布亦称为“半年频道”，支持期为 18 个月。Windows 10 also plans to target the March and September time frames for providing feature updates to Windows 10. Those releases will also be referred to as Semi-Annual Channel and also will be supported for 18 months.
配置供 Office 365 专业增强版使用的更新通道Configure the update channel to be used by Office 365 ProPlus
半年频道是 Office 365 专业增强版的默认更新通道。不过，可以将 Office 365 专业增强版安装配置为使用每月频道或半年频道（定向）。此外，并非组织中的所有用户都必须采用相同的配置。例如，可以执行下列操作：Semi-Annual Channel is the default update channel for Office 365 ProPlus. But you can configure an Office 365 ProPlus installation to use Monthly Channel or Semi-Annual Channel (Targeted). Also, not all users in your organization have to be configured the same. For example, you might do the following:
向一组试点用户提供每月频道，以便他们能够在 Office 新功能一推出就立即进行试用。Provide a group of pilot users with Monthly Channel, so they can try out the new features of Office as they become available.
向包含多个关键业务线应用的财务部门提供半年频道。Provide your finance department, which has several key line-of-business applications, with Semi-Annual Channel.
向应用兼容性测试人员提供半年频道（定向），以便他们能够测试财务应用是否与发布的下一个半年频道功能更新兼容。Provide your application compatibility testers with Semi-Annual Channel (Targeted) so that they can test that the finance applications will work with the next Semi-Annual Channel feature release.
若要配置 Office 365 专业增强版安装的更新通道，可以使用最新版 Office 部署工具，也可以使用适用于 Office 的组策略管理模板文件 (ADMX/ADML)。To configure the update channel for an Office 365 ProPlus installation, you can use the latest version of the Office Deployment Tool or use the Group Policy Administrative Template files (ADMX/ADML) for Office.
如果使用 Office 部署工具，可以使用 configuration.xml 文件中的 Channel 属性。可以在 Add 元素或 Update 元素中指定 Channel 属性。相关值为：每月频道对应于“Monthly”、半年频道对应于“Broad”、半年频道（定向）对应于“Targeted”。例如，若要下载并安装 Office 365 专业增强版的每月频道，configuration.xml 文件如下面的示例所示。If you use the Office Deployment Tool, you can use the Channel attribute in the configuration.xml file. The Channel attribute can be specified in the Add element or the Update element. The relevant values are "Monthly" for Monthly Channel, "Broad" for Semi-Annual Channel, and "Targeted" for Semi-Annual Channel (Targeted). For example, if you want to download and install the Monthly Channel of Office 365 ProPlus, your configuration.xml file would look like the following example.
<Configuration> <Add SourcePath="\\server01\office" OfficeClientEdition="32" Channel="Monthly"> <Product ID="O365ProPlusRetail" > <Language ID="en-us" /> </Product> </Add> </Configuration>
组策略设置名称为“更新通道”。此策略设置位于 Computer Configuration\Policies\Administrative Templates\Microsoft Office 2016 (Machine)\Updates 下。启用组策略设置时，可以从下拉列表中选择相应的更新通道。The name of the Group Policy setting is Update Channel. You can find this policy setting under Computer Configuration\Policies\Administrative Templates\Microsoft Office 2016 (Machine)\Updates. When you enable the Group Policy setting you can select the appropriate update channel from a drop-down list.
Office 365 专业增强版的更新通道的其他信息Additional information about the update channels for Office 365 ProPlus
下面介绍了其他一些信息，这些信息可能有助于决定如何在组织中配置和使用每月频道、半年频道和半年频道（定向）。Here is some additional information that might be useful to know as you determine how to configure and use Monthly Channel, Semi-Annual Channel, and Semi-Annual Channel (Targeted) in your organization.
可以将 Office 365 专业增强版安装从一个更新通道切换为另一个。例如，可能需要将用户从每月频道迁移到半年频道。若要切换更新通道，可以使用 Office 部署工具或组策略。You can switch an Office 365 ProPlus installation from one update channel to another. For example, you might want to move a user from Monthly Channel to Semi-Annual Channel. To switch update channels, you can use the Office Deployment Tool or Group Policy.
如果用户执行 Office 365 专业增强版的联机修复，安装将恢复为半年频道，除非已将组策略设置配置为提供其他更新通道。If the user does an Online Repair of Office 365 ProPlus, the installation reverts to Semi-Annual Channel, unless you've configured a Group Policy setting to provide a different update channel.
如果在 Office 365 专业增强版所在的同一台计算机上安装了 Visio Online 计划 2（以前称为 Visio Pro for Office 365）或 Project Online 桌面客户端，它们必须全都使用相同的更新通道。If you have Visio Online Plan 2 (previously named Visio Pro for Office 365) or Project Online Desktop Client installed on the same computer as Office 365 ProPlus, they all must use the same update channel. 您不能在同一台计算机上混合使用更新通道。You can't have a mix of update channels on the same computer.
这些更新通道仅适用于运行 Windows 的计算机上的安装。These update channels only apply to installations on computers running Windows.
建议使用最新版的半年频道。但是，您有特定业务需要延迟在 1 月或 7 月从半年频道接收功能更新，可以将 Office 配置为不接收该功能更新，但仍接收以前版本的最新安全更新。有关如何执行此操作的详细信息，请参阅延迟接收来自半年频道的功能更新。有关受支持的半年频道的版本和支持期限的信息，请参阅 Office 365 专业增强版更新的发布信息。We recommended that you use the most current version of Semi-Annual Channel. But, if you have a specific business need to delay receiving a feature update from Semi-Annual Channel in January or July, you can configure Office to not receive that feature update, but still receive the most current security updates for the previous version.
