GCP Release Notes: March 31, 2026

AlloyDB for PostgreSQL

Feature

Hot standby enhances the AlloyDB high availability (HA) architecture to improve failover times and to ensure consistent performance after failover. AlloyDB continuously replicates transactions to the standby node to keep caches warm and to ensure that the node is ready to take over quickly during a failover. This feature is generally available (GA) in PostgreSQL 18 and is automatically enabled for all new instances. For more information, see the AlloyDB high availability overview.

Apigee X

Feature

General Availability (GA) launch of Model Context Protocol (MCP) in Apigee

With this release, Model Context Protocol (MCP) in Apigee is generally available, enabling you to expose your Apigee APIs as MCP tools to agentic applications.

Any MCP client that supports remote MCP endpoints over HTTP/S can access these tools. Because the endpoints are managed, you don’t need to install or manage local MCP servers, remote MCP servers, or additional infrastructure to enable agentic applications to access your services.

MCP in Apigee is available for Subscription, Pay-as-you-go, and Evaluation organizations, including organizations with Data Residency and VPC Service Controls enabled.

For more information on using MCP in Apigee, see MCP in Apigee overview.

Change

Updated MCP server target endpoint for MCP Discovery Proxies

With the GA launch of Model Context Protocol (MCP) in Apigee, the structure of the MCP server target endpoint for MCP Discover Proxies has changed to ORG_NAME.mcp.apigee.internal.

Private preview customers using the previous format (mcp.apigee.internal) are encouraged to update their proxies to reflect the new structure. Existing endpoints using the old format will continue to work, but new endpoints will use the new structure.

Announcement

On March 31st, 2026, we released an updated version of Apigee.

Feature

Enhanced OAS server URL path handling for MCP in Apigee

With this feature enhancement, your OpenAPI specification (OAS) configurations behave exactly as defined in the OAS standard, automatically combining the server.url base path value with individual operation paths.

For example, a server URL ofhttps://example.com/api/v1 paired with a path of /users will now correctly route to https://example.com/api/v1/users without additional manual intervention.

If you previously prepended base paths to your OAS paths entries, remove the path segment from your servers.url field to prevent duplication. For example, change https://example.com/api/v1 to https://example.com.

For more information, see Create an OpenAPI 3.0 specification.

Issue

Known Issue 496552286: Deployment fails for MCP Discovery Proxies in regions with capacity limitations.

For more information, see Apigee known issues.

BigQuery

Feature

BigQuery ObjectRef values now support the following:

These features are generally available (GA).

Cloud NAT

Announcement

The default TCP TIME_WAIT timeout for Cloud NAT is scheduled to decrease from 120 seconds to 30 seconds, across all regions, as follows:

  • From June 30 to September 29, 2026: new Cloud NAT gateways will use either the 120-second or 30-second default, depending on when the update is deployed in a specific region.
  • On or after September 30, 2026: all new Cloud NAT gateways in all regions will use the 30-second default.

Impact on gateways

  • New gateways: after the update is deployed in a region, all new Cloud NAT gateways created in that region will use the 30-second default. This change also applies if a pre-update gateway is deleted and then recreated.
  • Existing gateways: Cloud NAT gateways created before the regional update will retain the 120-second default. You can adjust this value by using the –tcp-time-wait-timeout flag at any time.

    Cloud NAT gateways configured with a custom TIME_WAIT value aren’t affected and will continue to use your configured custom value.

The following table outlines the applicable default timeout for new gateways throughout the deployment timeline.

Gateway type Default timeout
(before June 30)
Default timeout
(June 30—September 29)
Default timeout
(on or after September 30)
New 120 seconds 30 or 120 seconds 30 seconds

Cloud SQL for MySQL

Feature

You can now migrate a subset of databases from an external server to a destination Cloud SQL for MySQL instance.

For more information, see Configure Cloud SQL and the external server for replication.

Cloud TPU

Feature

Generally available: TPU7x is generally available (GA). TPU7x is the first release within the Ironwood family, Google Cloud’s seventh generation TPU. TPU7x supports large-scale AI training and inference, providing performance and cost-effectiveness for demanding workloads such as large language (LLMs), mixture of experts (MoEs), and diffusion models. For more information, see the TPU7x (Ironwood) documentation.

Compute Engine

Feature

Generally available: The maximum throughput for a Hyperdisk ML disk is increased to 2,097,152 MiB/s from 1,200,000 MiB/s. Hyperdisk ML provides the highest throughput per disk for machine learning and for workloads that require high read throughput on immutable datasets.

For more information, see About Hyperdisk ML.

Document AI

Feature

Upgrading fine tuned custom extractor processors is now available in Preview.

The feature allows you to fine tune a new processor version with a newer base version, while keeping the configurations of the previously fine-tuned processor version selected. This is available through the UI in the Deploy & use tab in the console.

This is currently supported for upgrading pretrained-foundation-model-v1.4-2025-02-05 to pretrained-foundation-model-v1.5-2025-05-05.

For more information, see training overview.
