| * Introduction |
| |
| Today we released version 1.5.5 the Go App Engine SDK. |
| You can download it from the [[http://code.google.com/appengine/downloads.html][App Engine downloads page]]. |
| |
| This release includes changes and improvements to the App Engine APIs and |
| brings the supporting Go tool chain to [[https://golang.org/doc/devel/release.html#r60][release.r60.2]] |
| (the current stable release). |
| Also included in this release are the [[https://golang.org/cmd/godoc/][godoc]], |
| [[https://golang.org/cmd/gofmt/][gofmt]], |
| and [[https://golang.org/cmd/gofix/][gofix]] tools from the Go tool chain. |
| They can be found in the root directory of the SDK. |
| |
| 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. |
| |
| 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: |
| |
| /path/to/sdk/gofix /path/to/your/app |
| |
| The SDK now includes the appengine package source code, |
| so you can use the local godoc to read App Engine API documentation: |
| |
| /path/to/sdk/godoc appengine/datastore Get |
| |
| *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. |
| |
| See the [[http://code.google.com/p/googleappengine/wiki/SdkForGoReleaseNotes][release notes]] |
| for a full list of changes. |
| Please direct any questions about the new SDK to the [[http://groups.google.com/group/google-appengine-go][Go App Engine discussion group]]. |
