Add and drop hybrid table constraints online (General availability)
With this release, you can add and drop UNIQUE and FOREIGN KEY constraints on an existing hybrid table by using alter table . Previously, you had to define these constraints when you created the table, so adding a foreign key to a table that was already serving a workload meant recreating and reloading the table.
Shadow traffic for gateways (Preview)
With this preview release, you can use a shadow traffic gateway to send all production requests to a primary service endpoint while mirroring a percentage of those requests to one or more shadow endpoints. Responses from shadow endpoints aren't returned to clients.
The partner-powered AI features setting will be removed
On November 1, 2026, Databricks will remove the account- and workspace-level toggle for partner-powered AI features. Each workspace will keep its current setting value: if the setting is enabled, it stays enabled, and if it's disabled, it stays disabled. Removing the toggle doesn't change any setting values.
Incremental ingestion for Salesforce formula fields in Lakeflow Connect will soon be generally available

Buildkite for VS Code
The Buildkite VS Code extension is now available, bringing your pipelines and agents directly into your editor. You can browse and manage pipelines, view agent status, stream job logs, get build notifications, and validate pipeline YAML , all without leaving VS Code. Install it from the VS Code Marketplace .
Job logs are limited to 1 GiB
Job logs are now limited to 1 GiB (1,024 MiB) by default. You can check your organization’s current log size limit on the Quotas page . When a job log exceeds the limit, Buildkite cancels the job and adds a Log Size Limit Exceeded event to the timeline. Logs received prior to the limit being reached are retained.
Read-only GitHub Actions, Variables, and Environments permissions
To improve GitHub Actions migration support , the Buildkite GitHub App now requests read-only access to Actions , Variables , and Environments . These permissions let Buildkite inspect configuration that affects how workflows and deployments run, including configuration variables referenced through ${{ vars.* }} , secret names (not secret values)...
Buildkite Agent v4 is here
Buildkite Agent v4 is here. It's the first major version of the agent since v3 arrived in 2018, and it's now the stable release: installations and upgrades that follow the latest or stable channels now receive v4.
Understand pull request retry patterns with OpenTelemetry
Understand PR retry patterns in your existing observability tool, without joining webhook data. Buildkite's server-side OpenTelemetry traces include PR metadata, including for GitHub merge-queue builds, and job retry metadata to compare manual and automatic retries and follow attempts.
Elastic CI Stack v7 is here with Buildkite Agent v4
Elastic CI Stack for AWS v7 is now available, bringing Buildkite Agent v4 to both Linux and Windows instances. Agent v4 clears out functionality deprecated since v3 arrived in 2018 and makes supported behavior the default. New capabilities have continued shipping in v3, so for most setups the move changes nothing about how you use the agent.
Buildkite Helm chart: Slack App integration
The Buildkite Agent Stack for Kubernetes Helm chart now includes built-in support for Slack App integration. You can configure Slack notifications directly in your Helm values without needing a separate sidecar or custom webhook setup.
Test your schedules with or without edits
Run a pipeline schedule as configured, or customize a one-off build without changing the schedule. Helpful when you need to validate your schedules before turning them on. Two actions on the schedule page make the choice clear: Run now asks for confirmation, then creates a build using the schedule's saved message, commit, branch, and environment variables.
