Microsoft 365 应用版的更新通道概述Overview of update channels for Microsoft 365 Apps

Microsoft 365 应用版的一个优势是,Microsoft 定期为 Office 应用提供新增(和更新)功能,如 Excel 和 Word。One of the benefits of Microsoft 365 Apps is that Microsoft provides new (and updated) features for Office apps, such as Excel and Word, on a regular basis. 可通过指定更新频道来控制组织中的用户获取这些新功能的频率。You can control how often the users in your organization get these new features by specifying the update channel.

除新增功能外,每个月都会定期更新频道以提供所需的安全和非安全更新。In addition to new features, update channels provide, as needed, security and non-security updates on a regular basis, every month. 非安全更新提供对已知问题的修复,并为 Office 提供稳定性或性能改进。Non-security updates provide fixes for known issues and provide stability or performance improvements for Office.

有三个主要的更新频道:There are three primary update channels:

建议使用当前频道,因为它可以在最新的 Office 功能可用后尽快为用户提供。We recommend Current Channel, because it provides your users with the newest Office features as soon as they are ready. 如果需要对每个月发布这些新 Office 功能的时间有更多的可预见性,我们建议使用月度企业版频道。If you need additional predictability of when these new Office features are released each month, we recommend Monthly Enterprise Channel. 我们推荐在具有需要进行大量测试才能接收新功能的精选设备的情况下,使用半年度企业版频道。In those cases where you have select devices that require extensive testing before receiving new features, we recommend Semi-Annual Enterprise Channel.

但是,我们认识到有多种因素将确定你为 Microsoft 365 应用版部署选择的更新频道。But, we realize that there are multiple factors that will determine which update channel you select for your deployment of Microsoft 365 Apps. 例如网络带宽使用、最终用户培训和支持、业务线应用和其他组织要求。For example, network bandwidth utilization, end-user training and support, line-of-business applications, and other organizational requirements.

若要熟悉当前频道的下一功能版本中即将推出的新功能,建议使用当前频道(预览版)。To become familiar with the new features coming in the next feature release of Current Channel, we recommend that you use Current Channel (Preview).

当前频道(预览版)没有设定的发布计划。There isn’t a set release schedule for Current Channel (Preview). 一般来说,包含新功能的新版当前频道(预览版)将在新版本发布到当前频道之前至少一周或更早之前发布。In general, a new version of Current Channel (Preview) with new features is released at least a week or more before that new version is released to Current Channel. 在将该版本发布到当前频道前,可能有多个版本的当前频道(预览版),其中包含非安全更新。There might be several releases of Current Channel (Preview), with non-security updates, before that version is released to Current Channel.

  • 发布包含新功能的当前频道的新版本时When a new version of Current Channel is released with new features
  • 在每月的第二个星期二发布安全更新时。When security updates are released on the second Tuesday of the month

可在其他时间发布非安全更新。Non-security updates can be released at other times. 例如,通过最近发布的新功能修复某个问题。For example, to fix an issue with a new feature that was recently released. 一般来说,当前频道每月可获取两到三个仅包含非安全更新的更新。In general, Current Channel can get two or three updates per month that contain only non-security updates.

我们还鼓励你使用当前频道(预览版),以便在发布到当前频道之前识别希望我们修复的任何问题。We also encourage you to use Current Channel (Preview) so that you can identify any possible issues that you want us to fix before that version is released to Current Channel. 这可以帮助减少当前频道所需的非安全更新数量。This can help reduce the number of non-security updates that are needed for Current Channel.

非安全更新是累积的。当前频道的最新版本包括当前频道先前版本中的非安全更新。Non-security updates are cumulative. The most current release of Current Channel includes the non-security updates from previous releases of Current Channel.

无法单独下载当前频道的非安全更新。Separate downloads of just non-security updates for Current Channel aren’t available. 此外,不针对不再受支持的当前频道版本提供新的非安全更新。Also, new non-security updates aren’t provided for versions of Current Channel that are no longer supported. 它们被列为“已解决的问题”。They are listed as “Resolved issues.”

月度企业版频道Monthly Enterprise Channel overview

如果你希望每月为用户提供新的 Office 功能,但仅希望根据可预见的发布计划每月接收一次更新,我们推荐使用月度企业版频道。We recommend Monthly Enterprise Channel if you want to provide your users with new Office features each month, but only want to receive one update per month on a predictable release schedule.

月度企业版频道的更新在相应月份的第二个星期二发布。Updates to Monthly Enterprise Channel are released on the second Tuesday of the month. 该月度更新可包括功能、安全和非安全更新。This monthly update can include feature, security, and non-security updates.

月度企业版频道的功能更新Feature updates for Monthly Enterprise Channel

月度企业版频道的新增或更新功能在相应月份的第二个星期二发布。New, or updated, features are released in Monthly Enterprise Channel on the second Tuesday of the month. 这些新增功能是已面向当前频道中的所有用户提供的功能。These new features are features that are already available to all users in Current Channel. 无法单独下载月度企业版频道的功能更新。Separate downloads of just feature updates for Monthly Enterprise Channel aren’t available.

当前处于当前频道中的功能需要满足特定发布条件才能包含在月度企业版频道的功能更新中。Features that are currently in Current Channel need to meet certain release criteria before they are included in a feature update for Monthly Enterprise Channel. 因此,当前频道中的某些功能不会立即包含在月度企业版频道的下个可用功能更新中。Because of this, some features that are in Current Channel aren’t included right away in the next available feature update for Monthly Enterprise Channel.

有关月度企业版频道的给定版本中包含的功能更新列表,请参阅 Microsoft 365 应用版的发行说明For a list of feature updates included in a given release of Monthly Enterprise Channel, see Release notes for Microsoft 365 Apps releases.

预览月度企业版频道即将推出的新功能Preview upcoming new features of Monthly Enterprise Channel

没有适用于月度企业版频道的专用预览频道,就像当前频道和半年度企业版频道一样。There is no dedicated preview channel for Monthly Enterprise Channel, like there is for Current Channel and for Semi-Annual Enterprise Channel.

要熟悉月度企业版频道每月功能发布中的新功能,你可以在组织中拥有一个具有代表性的用户样本,并在 Office CDN 上提供新版本时立即下载并开始使用它。To become familiar with the new features in a monthly feature release of Monthly Enterprise Channel, you can have a representative sample of users in your organization download and start using the new version as soon as it becomes available on the Office CDN. 然后,在几天内将新版本推广到组织的其余部分,Office 会自动意识到 Office CDN 上有新版本可用。Then, let the new version roll out to the remainder of your organization over the course of several days as Office automatically becomes aware that a new version is available on the Office CDN.

如果你正在考虑将当前频道用作预览频道,请注意,你在当前频道中看到的新功能不一定与在月度企业版频道的下次每月功能更新中看到的相同。If you're thinking of using Current Channel as your preview channel, be aware that new features you see in Current Channel aren’t necessarily the same new features you’ll see in the next monthly feature update for Monthly Enterprise Channel. 这是因为当前频道可能包含仅可供部分用户使用的新功能,因为该功能将逐渐推出。月度企业版频道将仅包含已在当前频道中完全推出的功能。That’s because Current Channel can contain new features that are only available to a subset of users as the feature is gradually rolled out. Monthly Enterprise Channel will only contain features that have been completely rolled out in Current Channel. 因此,在当前频道中可用的新功能可能在几个月内无法在月度企业版频道中使用,因为该功能仍在当前频道中推出。Therefore, a new feature that's available in Current Channel might not be available in Monthly Enterprise Channel for several months, because the feature is still being rolled out in Current Channel.

月度企业版频道的安全更新Security updates for Monthly Enterprise Channel

如有需要,月度企业版频道的安全更新通常在相应月份的第二个星期二发布。If needed, security updates for Monthly Enterprise Channel are released on the second Tuesday of the month.

有关月度企业版频道的给定版本中包含的安全更新列表,请参阅 Microsoft 365 应用版安全更新的发行说明For a list of security updates included in a given release of Monthly Enterprise Channel, see Release notes for Microsoft 365 Apps Security Updates.

月度企业版频道的非安全更新Non-security updates for Monthly Enterprise Channel

如有需要,月度企业版频道的非安全更新通常在相应月份的第二个星期二提供。If needed, non-security updates for Monthly Enterprise Channel are provided on the second Tuesday of the month. 非安全更新提供对已知问题的修复,并为 Office 提供稳定性或性能改进。Non-security updates provide fixes for known issues and provide stability or performance improvements for Office.

如果有需要尽早修复的关键问题(例如,与数据丢失相关的问题),我们将提供包含修复程序的更新版本,而不是等待下次计划月度更新。If there is a critical issue that needs to be fixed sooner, such as one related to data loss, we will provide an updated release with the fix, instead of waiting for the next scheduled monthly update.

非安全更新是累积的。月度企业版频道的最新版本包括月度企业版频道先前版本中的非安全更新。Non-security updates are cumulative. The most current release of Monthly Enterprise Channel includes the non-security updates from previous releases of Monthly Enterprise Channel.

无法单独下载月度企业版频道的非安全更新。Separate downloads of just non-security updates for Monthly Enterprise Channel aren’t available. 此外,不针对不再受支持的月度企业版频道版本提供新的非安全更新。Also, new non-security updates aren’t provided for versions of Monthly Enterprise Channel that are no longer supported.

有关月度企业版频道的给定版本中包含的非安全更新列表,请参阅 Microsoft 365 应用版的发行说明For a list of non-security updates included in a given release of Monthly Enterprise Channel, see Release notes for Microsoft 365 Apps releases. 它们被列为“已解决的问题”。They are listed as “Resolved issues.”

月度企业版频道的支持期Support duration for Monthly Enterprise Channel

月度企业版频道的任何给定版本均可获得两个月的支持。Any given version of Monthly Enterprise Channel is supported for two months. 例如,在 8 月的第二个星期二发布的月度企业版频道版本在 10 月的第二个星期二前受支持。For example, the version of Monthly Enterprise Channel that is released on the second Tuesday of August is supported until the second Tuesday of October.

在任何给定时间,始终有两个受支持的月度企业版频道。At any given time, there are always two versions of Monthly Enterprise Channel that are supported. 要查看目前受支持的月度企业版频道版本,请参阅 Microsoft 365 应用版更新历史记录顶部的表格。To see which versions of Monthly Enterprise Channel are currently supported, refer to the table at the top of Update history for Microsoft 365 Apps.

半年度企业版频道Semi-Annual Enterprise Channel overview

我们仅对需要进行大量测试才能推出新 Office 功能的组织推荐半年度企业版频道来选择设备。We recommend Semi-Annual Enterprise Channel only for those select devices in your organization where extensive testing is needed before rolling out new Office features. 例如,为了遵守法规、政府或其他组织要求。For example, to comply with regulatory, governmental, or other organizational requirements. 或者,在有其他原因导致组织无法按高于一年两次的频率为用户提供新的 Office 功能的情况。Or, in those cases where there are other reasons why your organization can’t provide your users with new Office features on a more frequent basis than twice a year.

半年度企业版频道的更新在相应月份的第二个星期二发布。Updates to Semi-Annual Enterprise Channel are released on the second Tuesday of the month. 在一月和七月,该月度更新可包括功能、安全和非安全更新。In January and July, the monthly update can include feature, security, and non-security updates. 在其他月份,该月度更新可包括安全和非安全更新。In other months, the update can include security and non-security updates.

半年度企业版频道的功能更新Feature updates for Semi-Annual Enterprise Channel

在半年度企业版频道中,每年发布两次新增或更新的功能,分别在 1 月和 7 月的第二个星期二。New, or updated, features are released in Semi-Annual Enterprise Channel twice a year, on the second Tuesday in January and July. 在任何其他时间都不会向半年度企业版频道添加新功能。New features aren’t added to Semi-Annual Enterprise Channel at any other time. 无法单独下载半年度企业版频道的功能更新。Separate downloads of just feature updates for Semi-Annual Enterprise Channel aren’t available.

这些新增功能是已面向月度企业版频道中的所有用户提供的功能。These new features are features that are already available to all users in Monthly Enterprise Channel. 当前处于月度企业版频道中的功能需要满足特定发布条件才能包含在半年度企业版频道的功能更新中。Features that are currently in Monthly Enterprise Channel need to meet certain release criteria before they are included in a feature update for Semi-Annual Enterprise Channel. 因此,月度企业版频道中的某些功能不会立即包含在半年度企业版频道的下个可用功能更新中。Because of this, some features that are in Monthly Enterprise Channel aren’t included right away in the next available feature update for Semi-Annual Enterprise Channel.

有关半年度企业版频道的给定版本中包含的功能更新列表,请参阅 Microsoft 365 应用版的发行说明For a list of feature updates included in a given release of Semi-Annual Enterprise Channel, see Release notes for Microsoft 365 Apps releases.

预览半年度企业版频道即将推出的新功能Preview upcoming new features of Semi-Annual Enterprise Channel

若要熟悉半年度企业版频道的下一功能版本中即将推出的新功能,建议使用半年度企业版频道(预览版)。To become familiar with the new features coming in the next feature release of Semi-Annual Enterprise Channel, we recommend that you use Semi-Annual Enterprise Channel (Preview).

半年度企业版频道(预览版)每年发布两次新功能,分别在 3 月和 9 月的第二个星期二。Semi-Annual Enterprise Channel (Preview) is released with new features twice a year, on the second Tuesday in March and September. 这些新功能将在 4 个月后在半年度企业版频道中发布。This provides you with four months before those same new features are released in Semi-Annual Enterprise Channel. 如果需要,半年度企业版频道(预览版)也会在每个月的第二个星期二接收安全和非安全更新。Semi-Annual Enterprise Channel (Preview) also receives, if needed, security and non-security updates every month, on the second Tuesday of the month.

应将半年度企业版频道(预览版)部署到组织中的小型代表性用户样本。You should deploy Semi-Annual Enterprise Channel (Preview) to a small, representative sample of users in your organization. 这有助于在向拥有半年度企业版频道的用户更广泛地发布新功能之前,识别组织可能遇到的任何问题。This can help you identify any possible issues for your organization before those new features are released more broadly to your users that have Semi-Annual Enterprise Channel.

我们还鼓励你使用半年度企业版频道(预览版),以便在发布到半年度企业版频道之前的 4 个月识别希望我们修复的任何问题。We also encourage you to use Semi-Annual Enterprise Channel (Preview) so that you can identify any possible issues that you want us to fix in the four months before that version is released to Semi-Annual Enterprise Channel. 将版本发布到半年度企业版频道后,非安全更新的审批流程会变得更加严格。Once a version is released to Semi-Annual Enterprise Channel, the approval process for non-security updates becomes even more rigorous.

半年度企业版频道的安全更新Security updates for Semi-Annual Enterprise Channel

如有需要,半年度企业版频道的安全更新通常在相应月份的第二个星期二发布。If needed, security updates for Semi-Annual Enterprise Channel are released on the second Tuesday of the month.

如果有需要尽早修复的关键问题(例如,与数据丢失相关的问题),我们将提供包含修复程序的更新版本,而不是等待下次计划月度更新。If there is a critical issue that needs to be fixed sooner, such as one related to data loss, we will provide an updated release with the fix, instead of waiting for the next scheduled monthly update.

我们倾向于为半年度企业版频道提供比其他更新频道更少的非安全更新。We tend to provide fewer non-security updates for Semi-Annual Enterprise Channel than the other update channels. 部分原因是,由于客户反馈,大多数问题,已被识别并于早前在其他更新频道(如当前频道和月度企业版频道)中推出这些功能时得到修复。In part, that’s because most issues are identified, thanks to customer feedback, and fixed when the features are rolled out earlier in the other update channels, such as Current Channel and Monthly Enterprise Channel. 此外,许多客户要求我们提供不经常更改的更新频道,因为更改可能会要求他们执行另一轮合规性测试。Also, many customers have asked us to provide an update channel that doesn’t change often, because changes could require them to do another round of compliance testing. 因此,在我们批准将任何非安全更新发布到半年度企业版频道之前,我们将认真评估将更改引入更新频道的影响。So, before we approve the release of any non-security updates to Semi-Annual Enterprise Channel, we carefully assess the impact of introducing the change to the update channel. 可能会批准导致数据丢失或对大量使用半年度企业版频道的客户造成显著影响的关键问题。Critical issues that result in data loss, or significantly affect a large number of customers using Semi-Annual Enterprise Channel, are likely to be approved. 我们还鼓励你使用半年度企业版频道(预览版),以便识别希望我们在此版本发布到半年度企业版频道前 4 个月内修复的任何可能的问题。We also encourage you to use Semi-Annual Enterprise Channel (Preview), so that you can identify any possible issues you want us to fix in the four months before that version is released to Semi-Annual Enterprise Channel.

非安全更新是累积的。半年度企业版频道的最新版本包括半年度企业版频道先前版本的非安全更新。Non-security updates are cumulative. The most current release of Semi-Annual Enterprise Channel includes the non-security updates from previous releases of Semi-Annual Enterprise Channel.

无法单独下载半年度企业版频道的非安全更新。Separate downloads of just non-security updates for Semi-Annual Enterprise Channel aren’t available. 此外,不针对不再受支持的半年度企业版频道版本提供新的非安全更新。Also, new non-security updates aren’t provided for versions of Semi-Annual Enterprise Channel that are no longer supported.

有关半年度企业版频道的给定版本中包含的非安全更新列表,请参阅 Microsoft 365 应用版的发行说明For a list of non-security updates included in a given release of Semi-Annual Enterprise Channel, see Release notes for Microsoft 365 Apps releases. 它们被列为“已解决的问题”。They are listed as “Resolved issues.”

半年度企业版频道的支持期Support duration for Semi-Annual Enterprise Channel

半年度企业频道的任何给定版本均支持 14 个月。这意味着在 1 月发布的新版半年度企业版频道受支持到下一年 3 月,7 月版本则支持到下一年的 9 月。Any given version of Semi-Annual Enterprise Channel is supported for fourteen months. This means that the new version of Semi-Annual Enterprise Channel that is released in January is supported until March of the following year, and the July release is supported until September of the following year.

在任何给定时间,始终有两个受支持的半年度企业版频道。At any given time, there are always two versions of Semi-Annual Enterprise Channel that are supported. 要查看目前受支持的半年度企业版频道版本,请参阅 Microsoft 365 应用版更新历史记录顶部的表格。To see which versions of Semi-Annual Enterprise Channel are currently supported, refer to the table at the top of Update history for Microsoft 365 Apps.

半年度企业版频道提供更长的支持期,目的是为具有需要进行大量测试才能推出新 Office 功能的设备的组织提供更多时间和灵活性。The longer support duration for Semi-Annual Enterprise Channel is intended to provide more time and flexibility for those organizations that have devices that require extensive testing before rolling out new Office features. 例如,在组织必须遵守特定的法规、政府或其他组织要求的情况下。For example, in those cases where organizations have to comply with specific regulatory, governmental, or other organizational requirements. 更长的支持期使这些组织能够根据需要,一年仅部署一次新功能。The longer support duration gives these organizations the ability to deploy new features only once a year if needed.

如何配置和管理更新频道How to configure and manage update channels

更新频道特定于设备,并且仅适用于运行 Windows 的设备上的 Office 安装。Update channels are device-specific and apply only to installations of Office on devices running Windows. 对设备进行的更新频道选择不是跟随用户从一个设备到另一个设备的设置。The choice of an update channel for a device is not a setting that follows the user from device to device. 例如,如果用户在运行 Windows 的不同设备上工作,则可以将这些设备配置为使用不同的更新频道。For example, if a user works on different devices running Windows, those devices could be configured to use different update channels. 这意味着用户可以根据所使用的设备访问不同的 Office 功能。That means the user could have access to different Office features depending on which device they’re using.

此外,只能为一台设备配置一个更新频道。Also, you can only configure one update channel for a device. 例如,如果同一台设备上安装了 Office、Project 和 Visio,它们必须使用相同的更新频道。For example, if you’re installing Office, Project, and Visio on the same device, they all must use the same update channel. 不能在同一台计算机上混合使用更新频道。You can’t have a mix of update channels on the same device.

并非组织中的所有设备均配置相同的更新频道。Not all devices in your organization have to be configured with the same update channel. 例如,IT 人员和应用程序开发人员可能在当前频道(预览版),以便试用即将推出的新 Office 功能,而组织的其他人员则在月度企业版频道。For example, IT staff and application developers might be on Current Channel (Preview), so that they can try out upcoming new Office features, while the rest of the organization is on Monthly Enterprise Channel. 如果你决定在组织内实施不同的更新频道,请记住,用户组可能有权访问不同功能,具体取决于其所在的更新频道,这可能使用户组之间的协作更加困难。If you decide to implement different update channels within your organization, keep in mind that groups of users might have access to different features depending on which update channel they’re on, which might make collaborating between groups of users more difficult.

默认更新频道Default update channel

每个订阅产品都配置有一个默认更新频道。如果在设备上自行安装产品时未指定更新频道,则产品将配置为使用默认更新频道。Each subscription product is configured with a default update channel. If you don’t specify the update channel when you install the product by itself on a device, the product will be configured to use the default update channel.

当前频道是 Microsoft 365 商业应用版以及订阅版 Project 和 Visio 桌面应用的默认更新频道。Current Channel is the default update channel for Microsoft 365 Apps for business and the subscription versions of the Project and Visio desktop apps.

自 2020 年 6 月 9 日起,当前频道在大多数情况下还将作为 Microsoft 365 企业应用版的默认频道。As of June 9, 2020, Current Channel is also the default channel for Microsoft 365 Apps for enterprise in most cases. 有关详细信息,请参阅 更改 Microsoft 365 企业应用版的默认更新频道For more information, see Change to the default update channel for Microsoft 365 Apps for enterprise.

Microsoft 365 管理中心Microsoft 365 admin center

如果你允许用户从门户自行安装 Office,则可以指定他们安装的更新频道。If you allow your users to install Office for themselves from the portal, you can specify which update channel they install. 若要执行此操作,请使用管理员帐户登录 Microsoft 365 管理中心,转到“显示所有” > “设置” > “组织设置” > “服务” > “Office 安装选项”,然后为用户选择相应的更新频道。To do that, sign in to the Microsoft 365 admin center with your admin account, go to Show all > Settings > Org settings > Services > Office installation options, and then choose the appropriate update channel for your users. 此设置适用于租户中的所有用户,并且仅适用于从门户自行安装 Office 的用户。This setting applies to all users in your tenant and only applies to users that install Office for themselves from the portal.

管理更新频道Manage the update channel

安装 Office 后,可更改设备的更新频道。After Office is installed, you can change the update channel for a device. 有关如何执行此操作的详细信息,请参阅更改组织中设备的 Microsoft 365 应用版更新频道For more information on how to do that, see Change the Microsoft 365 Apps update channel for devices in your organization. 请记住,更改设备的更新频道后,用户有权访问的功能也将随之更改。Keep in mind that if you change the update channel for the device, the features that the user has access to will change. 例如,如果将设备从当前频道移动到半年度企业版频道,用户可能会失去对他们正在使用的功能的访问权限,因为这些功能在半年度企业版版频道中尚不可用。For example, if you move the device from Current Channel to Semi-Annual Enterprise Channel, the user might lose access to features that they’ve been using, because those features aren’t available yet in Semi-Annual Enterprise Channel.

其他产品Other products

  • 这些更新频道也适用于 Project 和 Visio 桌面应用的订阅版本。These update channels also apply to the subscription versions of the Project and Visio desktop apps. 例如,如果你拥有 Project 计划 3 或 Visio 计划 2。For example, if you have Project Plan 3 or Visio Plan 2.
  • OneDrive 和 Microsoft 团队拥有自己的更新节奏,它们独立于这些更新频道。OneDrive and Microsoft Teams have their own update cadences that are separate from these update channels. 有关详细信息,请参阅 OneDrive 同步应用更新过程Teams 更新过程For more information, see The OneDrive sync app update process and Teams update process.
  • 如果你要部署 Office 专业增强版 2019 或 Office 标准版 2019(两者均为 Office 批量许可版本),则需要使用其他更新频道。If you're deploying Office Professional Plus 2019 or Office Standard 2019, which are volume licensed versions of Office, there is a different update channel you need to use. 有关详细信息,请参阅 Office 2019 更新频道For more information, see Update channel for Office 2019.
  • 如果你拥有 Office 家庭版订阅(如 Microsoft 365 家庭版或 Microsoft 365 个人版),则当前频道是你唯一可用的更新频道,其他更新频道通过 Office 预览体验计划提供。If you have a home subscription of Office, such as Microsoft 365 Family or Microsoft 365 Personal, the only update channels available to you are Current Channel and the update channels available through the Office Insider program.

管理更新Managing updates

  • 要简化更新管理(尤其是对于当前频道和月度企业版频道),建议将设备配置为直接通过 Internet 上从 Office 内容交付网络 (CDN) 接收更新。To simplify managing updates, especially for Current Channel and Monthly Enterprise Channel, we recommend that you configure devices to receive updates directly from the Office Content Delivery Network (CDN) on the internet.
  • 如果将设备配置为直接从 Office CDN 获取更新,并且这些设备运行的是 Windows 10,则可利用传递优化来帮助降低网络带宽利用率。If you configure devices to get updates directly from the Office CDN, and those devices are running Windows 10, you can take advantage of Delivery Optimization to help reduce network bandwidth utilization.
  • 在 Office CDN 上提供新版本时,我们将在几天内逐步向全球安装了 Office 的设备公布此版本的可用性。When we make a new release available on the Office CDN, we gradually advertise the availability of this release over a period of several days to devices worldwide that have Office installed. 这样,组织中的所有设备就不会在同一时间尝试访问 Office CDN 以下载新版本,避免了可能导致的网络带宽利用率问题。This way not all devices in your organization will try to access the Office CDN at the same time to download the new release, which could possibly cause network bandwidth utilization issues.
  • 有关从当前频道的最近版本更新到最新版本的大约更新大小的示例,请参阅 Microsoft 365 应用版更新的下载大小For examples of approximate update sizes when updating from a recent release to the most current release of an update channel, see Download sizes for updates to Microsoft 365 Apps.
  • 如果使用 Microsoft Endpoint Configuration Manager,则可通过使用软件更新管理工作流来管理这些更新频道。If you use Microsoft Endpoint Configuration Manager, you can manage updates for these update channels by using the Software Update management workflow. 有关详细信息,请参阅使用 Microsoft Endpoint Configuration Manager 管理 Microsoft 365 应用版更新For more information, see Manage updates to Microsoft 365 Apps with Microsoft Endpoint Configuration Manager.

版本和内部版本信息Version and build information

  • 要查看为 Office 配置的更新频道,请打开 Office 应用(如 Word),然后转到“文件” > “帐户”。To see the update channel that Office is configured for, open an Office app, such as Word, and go to File > Account. 更新频道的名称将显示在“关于”标题的“产品信息”部分。The name of the update channel appears in the Product Information section under the About heading. 更新频道的版本号和内部版本号也会显示在此处。The version and build number for the update channel are also shown there.
  • 如果更新频道发布包含功能更新,将更新版本号。When an update channel release contains feature updates, the version number is updated. 例如,从版本 2004 更新到版本 2005。For example, from Version 2004 to Version 2005. 如果发布仅包含新的安全更新或非安全更新,则只会更新内部版本号,版本号将保持不变。If a release contains only new security updates or new non-security updates, then only the build number gets updated and the version number remains the same.

其他更新频道的支持期Support duration for other update channels

  • 当前频道(预览版)的任何给定版本仅支持到下一版当前频道(预览版)发布为止,时间通常为每个月。例如,版本 2004 的支持到版本 2005 发布为止。Any given version of Current Channel (Preview) is supported only until the next version of Current Channel (Preview) is released, which is usually every month. For example, Version 2004 is supported until Version 2005 is released.
  • 半年度企业版频道(预览版)的任何给定版本均只能获得六个月的支持。Any given version of Semi-Annual Enterprise Channel (Preview) is supported for only six months. 这与半年度企业版频道(预览版)的新功能更新频率相符。This coincides with how often Semi-Annual Enterprise Channel (Preview) is updated with new features. 例如,在 3 月发布的具有新功能的半年度企业版频道(预览版)的版本在九月前受支持,即半年度企业版频道(预览版)下次发布新功能的时间。For example, the version of Semi-Annual Enterprise Channel (Preview) that is released in March with new features is supported until September, which is the next time new features are released in Semi-Annual Enterprise Channel (Preview). 九月发布的版本在次年三月前受支持。The September release is supported until the following March. 要查看目前受支持的半年度企业版频道(预览版)的版本,请参阅 Microsoft 365 应用版更新历史记录顶部的表格。To see what version of Semi-Annual Enterprise Channel (Preview) is currently supported, refer to the table at the top of Update history for Microsoft 365 Apps.

Office 预览体验成员计划Office Insider program

  • Office 预览体验计划通过这些更新频道使你能够及早访问 Office 功能:Beta 版本频道和当前频道(预览版)。The Office Insider program gives you early access to Office features through these update channels: Beta Channel and Current Channel (Preview). 有关详细信息,请参阅适用于企业的 Office 预览体验计划For more information, see Office Insider for Business.
  • Beta 版本频道(以前称为“预览体验计划”,有时称为“预览体验计划(快)”)可提供对新功能的访问权限,甚至在当前频道(预览版)中提供这些功能之前。Beta Channel, which was previously named Insider (and sometimes referred to as Insider Fast), provides access to new features even before they are available in Current Channel (Preview). 但是,Beta 版本频道 受支持,因此只能由一小组选定用户(如 IT 人员或应用程序开发人员)在测试环境中使用。But, Beta Channel is not supported so should only be used in test environments and by a small group of select users, such as IT staff or application developers.
