|
|
|
|
|
|
Today we released version 1.5.5 the Go App Engine SDK.
|
|
You can download it from the [App Engine downloads page](http://code.google.com/appengine/downloads.html).
|
|
|
|
This release includes changes and improvements to the App Engine APIs and
|
|
brings the supporting Go tool chain to [release.r60.2](/doc/devel/release.html#r60)
|
|
(the current stable release).
|
|
Also included in this release are the [godoc](/cmd/godoc/),
|
|
[gofmt](/cmd/gofmt/),
|
|
and [gofix](/cmd/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 [release notes](http://code.google.com/p/googleappengine/wiki/SdkForGoReleaseNotes)
|
|
for a full list of changes.
|
|
Please direct any questions about the new SDK to the [Go App Engine discussion group](http://groups.google.com/group/google-appengine-go).
