GCP Release Notes: June 02, 2026

AlloyDB for PostgreSQL

Feature

You can now configure a cooldown period to determine when autoscaling occurs for your read pool instances. For more information, see Scale an instance.

Cloud Composer

Feature

(Managed Airflow Gen 3) You can now access Cloud Run endpoints restricted to internal ingress traffic through your environment’s network attachment. This feature is available through gcloud CLI beta commands and beta Cloud Composer API in all Managed Airflow (Gen 3) versions.

Cloud Load Balancing

Feature

TLS post-quantum key exchange support is now available for Application Load Balancers and external proxy Network Load Balancers. Post-quantum key exchange is essential for protecting today’s traffic from future quantum computing decryption risks (harvest now, decrypt later attacks). With post-quantum key exchange enabled, the load balancer uses post-quantum key exchange with clients that support TLS 1.3 and X25519MLKEM768 key exchange.

This feature is rolling out in three phases:

• Phase 1 (Until October 2026): Post-quantum key exchange is not enabled by default. Customers can elect to opt in and enable it using their SSL policy.

• Phase 2 (October 2026 through October 2027): The feature is enabled by default. Customers can elect to defer (opt out) if required.

• Phase 3 (After October 2027): The feature is enabled by default, and options to defer are no longer effective.

We strongly encourage you to enable post-quantum key exchange now, even before it is turned on by default. The opportunity to test this today will help you verify that clients and any intermediate network devices can properly negotiate post-quantum key exchange.

For more information, see Post-quantum key exchange.

Cloud Monitoring

Feature

Support for Histogram widgets on custom dashboards is generally available. These widgets extract the most recent value from each time series, group those values into ranges, and then provide a graphical representation of the result. Unlike tables or other widgets that display the most recent values, Histograms display information about the relative frequency of ranges of values.

This widget is one of several visualizations that you can use to display the most recent values. For more information, see the following documents:

• Configure a histogram (Google Cloud console)
• Dashboard with an XyChart configured as a histogram (API)

Cloud Trace

Feature

The create-observability bucket flow enforces organization policies with constraints on resource locations. This flow also enforces policies that require customer-managed encryption keys (CMEKs) and that restrict the projects that store those keys. Your trace data is stored in an observability bucket.

For more information, see the following:

• Set defaults for observability buckets
• Support for CMEKs

Datastream

Feature

Datastream now offers a free tier for change data capture (CDC) data processed from Google Cloud sources, such as AlloyDB for PostgreSQL and Spanner. You get the first 100 GiB of CDC data for free per billing account, per month.

For more information, see the Pricing page.

Filestore

Feature

You can configure your Filestore instances to use Private Service Connect with NFSv3 or NFSv4.1 file system protocols and IPv4 or IPv6 address families to allow consumers access managed services privately from inside their VPC network. This feature is generally available.

For more information, see Create a Filestore instance with Private Service Connect.

NetApp Volumes

Announcement

Google Cloud NetApp Volumes Flex Unified service level is available with limited performance in the following region:

• us-east5 (Columbus)

For more information about limited performance regions, see Supported regions for Flex Unified limited performance.
