In the App Engine page in the Google Cloud console, you can now filter your existing App Engine versions by runtime lifecycle stages. After you apply this filter, the console displays a warning icon for App Engine versions that are approaching end of support, have reached end of support, are deprecated, and are decomissioned.

July 12, 2024

Deployments for new projects might be impacted from the following changes to org policies:

  • Starting in May 2024, Google Cloud enforces secure-by-default organization policies for all organization resources. This policy prevents App Engine from granting the Editor role to the App Engine default services accounts by default.

  • Starting in June 2024, Cloud Build has changed the default behavior for how Cloud Build uses service accounts in new projects. This change is detailed in Cloud Build Service Account Change. As a result of this change, new projects deploying versions for the first time may be using the default App Engine service account with insufficient permissions for deploying versions.

If you are impacted by this change you can do one of the following:

  • Grant the Editor role to the App Engine default service account.

  • Review the Cloud Build guidance on changes to the default service account and opt out of these changes.

March 12, 2024

You can't use the latest version of dev_appserver.py to locally run your applications for runtimes that reached end of support. To continue using an archived version of dev_appserver.py, see Use the local development server after runtimes reach the end of support.

January 31, 2024

Java 8 has reached end of support on January 31, 2024. Your existing Java 8 applications will continue to run and receive traffic. However, App Engine might block re-deployments of applications that use runtimes after their end of support date. We recommend that you migrate to the latest supported version of Java.

January 25, 2024

The Java 8 runtime doesn't support the GAE_PROFILER_MODE environment variable anymore. To continue using the Profiler agent, you must migrate your app to the latest supported version of Java. To configure the Profiler agent for your second-generation Java application, see Profiling Java applications.

App Engine is changing the URLs that you use to send requests to your apps. URLs now include a region ID to help Google route your requests more efficiently and reliably. For example, an app can receive requests at https://<var>PROJECT_ID</var>.<var>REGION_ID</var>.r.appspot.com. This new URL is optional for existing apps and is provided for all new apps.

To ensure a smooth transition, we are slowly updating App Engine to use region IDs. If we haven't updated your Google Cloud project yet, you won't see a region ID for your app. Since the ID is optional for existing apps, you don't need to update URLs or make other changes once the region ID is available for your existing apps.

May 15, 2018

  • Completed a gradual rollout of an upgrade to the automatic scaling system:
    • Improved efficiency resulting generally in lower instance cost (up to 6% reduction for many users) and up to 30% reduction for loading requests, which are the first request to a new instance.
    • New max instances setting allows you to cap the total number of instances to be scheduled.
    • New min instances setting allows you to specify a minimum number of instance to keep running for your app.
    • New target CPU utilization setting lets you optimize between latency and cost.
    • New target throughput utilization setting lets you optimize for the number of concurrent requests at which new instances are started.
    • No more resident instances in auto scaling. Previously, if you used the min_idle_instances setting, the minimum idle instances were labelled as Resident in the Cloud Console, with the remainder of the instances labelled as Dynamic. The new scheduler simply labels all instances as Dynamic with auto scaling. However, the underlying behavior remains similar to previous behavior. If you use min_idle_instances and enable warmup requests, you will see at least that many dynamic instances running even during periods with no traffic.
    • For more details, see the auto scaling documentation.

What's New

Known Java 8 Runtime Limitations

  • The /tmp directory is writable. Files in /tmp will consume memory allocated to your instance.
  • Async Servlet 3.1 is not supported.
  • WebSocket is not supported.
  • The Jetty 9 configuration cannot be modified.
  • App Engine APIs can only be called from the thread that handles a web request or from threads created using ThreadManager
  • WEB-INF/appengine-web.xml must be used for configuration, app.yaml is not currently supported.
  • Deployment must be done through the Maven, Gradle, or IDE plugins.
  • If you create a thread pool using for example ExecutorService pool = Executors.newCachedThreadPool(ThreadManager.currentRequestThreadFactory()) then it must be shutdown down explicitly using pool.shutdown() before the current request terminates.
  • Previously it was possible to reference vendored classes like com.google.appengine.repackaged.org.joda.Instant inadvertently when just org.joda.Instant was intended. The vendoring scheme has changed so code that did that no longer works.
  • Native network APIs (for example HttpURLConnection) are enabled for billed applications, but will return an exception (java.net.SocketTimeoutException or java.io.IOException) when used in free applications. Free applications can access *.googleapis.com and accounts.google.com, and they can also be configured to use the URLFetch service.
  • The google-cloud-java APIs need to be wrapped in an executor. See Pub/Sub Publisher hangs unless submitted through an executor.
  • Cloud Endpoints must be migrated from v1 to v2.
  • Channels and XMPP APIs are not supported.
  • appengine-labs-api.jar APIs are not supported resulting in Appstats for Java not being supported.
  • The Java 8 runtime default is to use the native Java HTTP(S) transport, not the URL Fetch transport, as is the case for Java 7 runtime. For more information, see url-stream-handler.

  • The error returned by URL Fetch for a request to a port outside of the permitted ranges (80-90, 440-450, 1024-65535) will now always return INVALID_URL as documented.

Cloud Datastore

  • When committing a cross-group transaction, version numbers returned for new or updated entities are all the same. With the previous behavior, entities within the same group committed as part of a cross-group transaction, had the same version number, but entities in different groups might have had different version numbers. This change ensures all new and updated entities have an identical version number, regardless of their entity group, when committed as part of a cross-group transaction. As before, entities that are not updated will not have a new version number.

Version 1.9.36

In response to your requests, the App Engine Users API joins the rest of App Engine in supporting IAM roles and group expansion. This means that any user who is a project Owner, Editor or Viewer or an App Engine Admin is considered an "admin" by the Users API, regardless of whether the user was granted the role directly or by membership in a group. * This release populates error details, when available, in error messages associated with the "OverQuota" exception type.

Java runtime notes

  • Google no longer accepts quota increase requests for the mail service. Customers should use Sendgrid instead.

Version 1.9.32

  • Container construction choices for Managed VMs

    The gcloud preview app deploy (and mvn gcloud:deploy) commands upload your artifacts to our servers and build a container to deploy your app to the Managed VM environment.

    There are two mechanisms for building the container image remotely. The default behavior is to build the container on a transient Compute Engine Virtual Machine which has Docker installed. Alternatively, you can use the Cloud Build service. To use the Cloud Build service, follow these steps:

    1. Activate the Cloud Build API for your project.
    2. Use the command gcloud config set app/use_cloud_build True. This will cause all invocations of gcloud preview app deploy to use the service. (To return to the default behavior, use the command gcloud config set app/use_cloud_build False.

Java runtime notes

  • Improved exception handling for the low-level API for Datastore, Transaction.rollback(). Instead of an exception, it generates an INFO log message when an operation associated with the transaction has failed.

Version 1.9.31

App Engine now supports Google Groups: Adding a Google Group as a member of a project grants the members of the group access to App Engine. For example, if a Google Group is an Editor on a project, all members of the group now have Editor access to the App Engine application.

Version 1.9.30

Headers for push queue requests made for Task Queue tasks with no payload will now contain a Content-Length entry set to '0'. Previously headers for such requests contained no Content-Length entry.

Version 1.9.29

  • Stop calculating and storing queue depth for non-existent queues, queues marked for deletion, and in the case of queue table outages.
  • For developers using the endpoints API, added a discoverable boolean parameter to the @Api annotation to allow users to disable API discovery. Using this feature will prevent some client libraries (e.g. JavaScript) and the API Explorer from working, as they depend on discovery.

Version 1.9.28

The Prospective Search API, which was deprecated on July 14, 2015, is now restricted to existing users. It will fully shutdown on December 1, 2015.

Improved accuracy of Geo filtering in Search queries.

Java runtime notes

  • Disabled Files API in the Java DevAppServer.

September 25, 2015

Version 1.9.27

Applications that are newly enabled for billing now default to an unlimited daily budget, and no longer default to a maximum daily budget of $0. This prevents unwanted outages due to running out of budget. To set a ceiling on your application's daily cost, after you enable billing, set a budget in the app engine settings. For more information, see Setting a daily budget.

Datastore

  • Bugfix: Repeated numeric facets are now allowed.
  • Faceted Search is now GA.

Version 1.9.26

  • oauth2client library upgraded to version 1.4.2
  • Adds "show in context" menu for MVM application logs that have thread_id or request_id as a field in their log entry. This allows sorting app logs based on either field.
  • Capability to provision applications for current load and configure elastic provisioning based on both VM and application level metrics.
  • Remote API can now be accessed using OAuth2 credentials using https://developers.google.com/identity/protocols/application-default-credentials
  • Use RequestPayloadTooLargeException for URLFetch requests with payloads that are too large.

Java runtime notes

  • Java's URLFetch API gains a property to specify default fetch deadline. appengine.api.urlfetch.defaultDeadline is a floating point number in seconds that can be used to specify a default URLFetch timeout for Java in appengine-web.xml.
