To increase security, starting in March 2025, support for Transport Layer Security (TLS) version 1.1 and earlier is deprecated. Update your application settings in the App Engine standard environment to use TLS version 1.2 and later, along with a corresponding secure set of cipher suites (Preview).
]]>Support for the Ruby 3.4 runtime is in General Availability (GA).
]]>Support for Ruby 3.4 runtime is in Preview.
]]>Container Registry is now shut down. We recommend that you use Artifact Registry for storing and managing container images. By default, new deployments created after March 5, 2025, use Artifact Registry instead of Container Registry for storing application build images. For more information, see Migrate App Engine container images to Artifact Registry.
]]>For new projects you create after March 2025, App Engine sets the automatic scaling maximum instances default for standard environment deployments to 20. This change doesn't impact existing apps. To override the default, specify a new max_instances value in your app.yaml file, and deploy a new version or redeploy over an existing version.
Custom organization policies for Serverless VPC Access connectors are now generally available, and can be applied to projects, folders, or organizations.
]]>Ruby 3.3 is now generally available.
]]>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.
]]>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.
Ruby 3.3 is now available in preview.
]]>Ruby 2.5, 2.6, and 2.7 have reached end of support on January 30, 2024. Your existing applications using these versions 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 upgrade to the latest supported version of Ruby.
]]>The option to update a Serverless VPC Access connector is now available at general availability (GA). This feature allows you to edit the machine (instance) type, as well as the minimum and maximum number of instances.
]]>A warning message now appears before you publish a container image to a public repository.
]]>Accessing a service that's prohibited by the Internal or Internal and Cloud Load Balancing ingress setting now results in a 404 rather than 403 error code.
Memory limits for second-generation runtimes have been increased to better support the growing memory utilization of many newer runtimes.
]]>The Ruby 3.2 runtime for App Engine standard environment is now generally available.
]]>The Ruby 3.2 runtime for App Engine standard environment is now available in preview.
]]>The option to update a Serverless VPC Access connector is now available in preview. This feature allows you to edit the machine (instance) type, as well as the minimum and maximum number of instances.
]]>You can now use any configured service account in your Cloud project as the app-level default service account, while creating and updating your App Engine applications.
]]>Build environment variables support is now generally available.
]]>Specifying a user-managed service account for each App Engine version during deployment is now generally available.
]]>The Ruby 3.0 runtime for App Engine standard environment is now generally available.
]]>Support for Serverless VPC Access connectors in Shared VPC host projects is now at general availability (GA). Learn about the advantages of this method and how to configure connectors in host projects.
]]>The Ruby 3.0 runtime for App Engine standard environment is now available in Preview.
]]>Builds are now handled by regional Cloud Build pools within the selected App Engine region. To view build logs, go to Cloud Build in the Cloud Console, select the History page, and select the region you would like to filter by.
]]>Egress settings for Serverless VPC Access are now generally available. Egress settings allow you to specify whether or not to send traffic with external destinations through your Serverless VPC Access connector, which is necessary if you want to set up a static outbound IP address for your App Engine service.

Egress settings allow you to specify whether or not to send traffic with external destinations through your Serverless VPC Access connector, which is necessary if you want to set up a static outbound IP address for your App Engine service.
]]>Requests from newly created or updated App Engine Cron jobs sent to the App Engine standard environment now come from 0.1.0.2. For Cron jobs created with older gcloud versions (earlier than 326.0.0), Cron requests will come from 0.1.0.1. Previously, these requests only came from 0.1.0.1. See Understanding the App Engine firewall for more information.
Specifying a user-managed service account for each App Engine version during deployment is now available in preview. This feature lets you grant different privileges to each version, based on the specific tasks it performs, and avoid granting more privileges than necessary.
]]>App Engine is now available in the us-west1 (Oregon), asia-southeast1 (Singapore), and asia-east1 (Taiwan) regions.
Automatic scaling elements min_instances and min_idle_instances will now only apply to versions of a service that have been configured to receive traffic. This change is to reduce unexpected billing due to instances running old versions that are not intended to receive traffic.
