Today we released version 1.5.5 the Go App Engine SDK. You can download it from the App Engine downloads page.
今天我们发布了1.5.5版本的Go App Engine SDK。您可以从App Engine的下载页面下载它。
This release includes changes and improvements to the App Engine APIs and brings the supporting Go tool chain to release.r60.2 (the current stable release). Also included in this release are the godoc, gofmt, and gofix tools from the Go tool chain. They can be found in the root directory of the SDK.
这个版本包括对App Engine APIs的修改和改进，并将支持Go的工具链提升到release.r60.2（当前的稳定版本）。这个版本还包括Go工具链中的godoc、gofmt和gofix工具。它们可以在SDK的根目录中找到。
Some changes made in this release are backwards-incompatible, so we have incremented the SDK api_version to 3. Existing apps will require code changes when migrating to api_version 3.
这个版本中的一些变化是向后兼容的，所以我们将SDK的api_version增加到了3。现有的应用程序在迁移到api_version 3时需要修改代码。
The gofix tool that ships with the SDK has been customized with App Engine-specific modules. It can be used to automatically update Go apps to work with the latest appengine packages and the updated Go standard library. To update your apps, run:
与SDK一起提供的gofix工具已经用App Eng的特定模块进行了定制。它可以用来自动更新Go应用程序，使其与最新的appengine软件包和更新的Go标准库一起使用。要更新您的应用程序，请运行：

Important note: We have deprecated api_version 2. Go apps that use api_version 2 will stop working after 16 December 2011. Please update your apps to use api_version 3 before then.
重要提示：我们已经废弃了api_version 2。使用api_version 2的Go应用程序将在2011年12月16日后停止工作。请在那之前更新您的应用程序以使用api_version 3。
