# FreeBSD 2.1.7-RELEASE 发行公告

FreeBSD 2.1.7 现可从以下地址获取：

<ftp://ftp.FreeBSD.org/pub/FreeBSD/2.1.7-RELEASE>

各镜像站点也将很快提供，镜像站点列表可从以下地址获取：<http://www.FreeBSD.org/handbook/mirrors.html>

这是 FreeBSD 2.1.6 的安全版本，修复了至少若干安全漏洞，并处理了该版本中一些悬而未决的问题报告。

FreeBSD 2.1.7 还将由 [Walnut Creek CDROM](http://www.cdrom.com/) 提供 CD-ROM 版本，预计在未来 3-4 周内发货。如果你是 Walnut Creek CDROM 的客户且已购买 2.1.6 版本（无论是通过订阅还是零售），则你有权获得**免费升级**。你只需发送邮件至 <orders@cdrom.com> 或拨打 1-800 786-9907 / +1 510 674-0783（国际），说明你希望获得免费的 2.1.7 升级，并提供你的姓名和地址信息以便寄送替换光盘。Walnut Creek CDROM 的客户还将收到一封说明这些详情的信函。

对 2.1.7 和 2.2 几乎同时发布感到困惑的用户，也可访问 <http://www.FreeBSD.org/> 了解此发布计划背后的原因。CD-ROM 订阅客户也应查看此页面，以了解 Walnut Creek CDROM 对这些版本的发行计划。

如果你是 FreeBSD 的商业用户，希望利用最近的漏洞修复而不愿直接升级到我们更具进取心的 2.2 版本（或者希望推迟到 2.2 更加成熟后再升级），又或者你只是想从 2.1.5 进行影响最小的升级，那么 2.1.7-RELEASE 就是为你准备的。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://book.bsdcn.org/release/freebsd-2.1.7-release/2.1.7-announce.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
