| * Introduction |
| |
| The Go and App Engine teams are excited to announce that the Go runtime |
| for App Engine is now generally available. |
| This means you can take that Go app you've been working on (or meaning to |
| work on) and deploy it to App Engine right now with the new [[http://code.google.com/appengine/downloads.html][1.5.2 SDK]]. |
| |
| Since we announced the Go runtime at Google I/O we have continued to [[http://code.google.com/p/googleappengine/wiki/SdkForGoReleaseNotes][improve and extend]] |
| Go support for the App Engine APIs and have added the Channels API. |
| The Go Datastore API now supports transactions and ancestor queries, too. |
| See the [[https://code.google.com/appengine/docs/go/][Go App Engine documentation]] |
| for all the details. |
| |
| For those who have been using the Go SDK already, |
| please note that the 1.5.2 release introduces `api_version` 2. |
| This is because the new SDK is based on Go `release.r58.1` (the current |
| stable version of Go) and is not backwards compatible with the previous release. |
| Existing apps may require changes as per the [[https://golang.org/doc/devel/release.html#r58][r58 release notes]]. |
| Once you've updated your code, you should redeploy your app with the line |
| `api_version:`2` in its `app.yaml` file. |
| Apps written against `api_version` 1 will stop working after the 18th of August. |
| |
| Finally, we owe a huge thanks to our trusted testers and their many bug reports. |
| Their help was invaluable in reaching this important milestone. |
