Release notes

4.1.0 | Jul 7, 2026

This release is only available for Managed Cloud Commercial deployments.

New features and enhancements

Admin Center

• AI Unit consumption tracking: Administrators can now see AI Unit consumption directly in the Admin Center, with hourly usage, per-user breakdowns, and consumption against your contract, alongside custom usage thresholds and alerts. Administrators can optionally enable automatic blocking of new resource usage once consumption reaches 100% of the contract threshold. (Available when AI Unit consumption tracking is enabled for your deployment.)
• Configure Domains: A new Configure Domains panel on the User Management page lets tenant administrators define which email domains are permitted for member invitations. Domains can be added in bulk and are normalized and de-duplicated automatically, invalid entries are flagged inline before saving, and a status bar shows whether the environment is open to all domains or restricted. A "last updated by" label shows who last changed the list and when, in your local time.

Navigation

• Clearer AI Units usage: The AI Units pill in the navigation bar now shows current usage on hover instead of an alert card, and a pointer cursor makes clear it's clickable for a full breakdown. When resource blocking is in effect, the banner now points you to your administrator and links to documentation explaining how AI Unit consumption is calculated.

4.0.12 | Jul 13, 2026

New features and enhancements

• Session signing key rotation: Operators can now rotate the session signing key without disrupting active sessions. Setting H2O_CLOUD_SESSION_KEYS_PREVIOUS to the outgoing key lets existing sessions validate against it while new sessions use the current key.

Bug fixes

• Fixed recurring session errors across sign-in paths: A session cookie signed with a rotated or invalid key no longer causes 500 errors (securecookie: the value is not valid / failed setting user context). The platform now treats an undecodable cookie as an absent session, clears it, and prompts a fresh sign-in. This fix covers browser cookies, OIDC, API tokens, service accounts, and sign-out flows.
• Fixed OIDC sign-in flow dropping incomplete sessions: The OIDC sign-in flow now restarts cleanly when it encounters an incomplete session, preventing users from being stranded during single sign-on authentication.
• Fixed Audit Trail metadata filtering: Metadata searches now send the correct filter fields, so filtering by a metadata key or value returns matching events.
• Fixed Audit Trail status code filtering: The Status Code filter now displays human-readable status labels (such as OK and INVALID_ARGUMENT) while querying the underlying numeric codes, so status searches return the correct results.
• Updated H2O CLI to version 1.14.2.
• Updated Go to 1.26.5, containerd, runc, and other server dependencies to address security vulnerabilities.

4.0.11 | Jul 6, 2026

Bug fixes

• Fixed Workflows UI authorization checks: Workflows navigation, run visibility, and workflow detail actions now check the same permissions enforced by the Workflows API. The "List runs from all workspaces" option on the All Runs page appears only for users entitled to view runs across workspaces, and workflow detail pages and the Run workflow action now correctly reflect each user's access.
• Fixed feature downloads in Feature Store: The Download features action now targets the correct Feature Store API endpoint, so downloading a feature set's features as CSV completes reliably.
• Updated H2O CLI to version 1.14.1.
• Updated Go dependencies to address security vulnerabilities.

4.0.9 | Jun 19, 2026

New features and enhancements

MLOps

• Update real-time deployments with unidentifiable runtime images: Real-time deployments built on older runtime images where the current runtime cannot be determined can now be updated to the latest runtime directly from the UI. Previously these deployments showed no available upgrade path; the update is now surfaced and can be applied from the deployment page.

Bug fixes

• Fixed Admin AI Engines page for administrators with the list-all permission: Administrators with this permission can now reach the page without encountering an authorization error.

4.0.8 | Jun 16, 2026

Bug fixes

• Fixed Admin AI Engines page for administrators with the list-all permission: Administrators granted this permission can now see the full engine list as expected.
• Fixed log streaming and download for app instances and AI engines: The Logs page now uses the correct API scope for each service, so logs stream and download reliably for both app instances and AI engines.

4.0.7 | Jun 15, 2026

New features and enhancements

Workflows

• Required parameters at the top of the run dialog: When launching a workflow run, required input parameters now appear above optional fields so you can see exactly what must be filled in before the run starts.
• Engine Profile YAML fields can be cleared: Clearing an Engine Profile YAML field no longer leaves a stale validation error.

Downloads

• Public downloads now served over CDN: Public download links for release artifacts, notifications, test data, Enterprise Steam, and documentation now point to CloudFront CDN endpoints on a .com domain. Downloads are faster, and customers whose networks block the .ai TLD can now access these resources.

Bug fixes

• Fixed MLOps Real-time Deployments page crash for older runtime images: The deployments page now loads correctly across all workspaces, including workspaces with deployments built on older runtime images. When the current runtime image cannot be determined, a "Runtime image information unavailable" message is shown on both the deployments list and the deployment detail page.
• Updated H2O CLI to version 1.14.0.
• Updated Go toolchain to 1.26.4 to address security vulnerabilities.

4.0.6 | Jun 5, 2026

New features and enhancements

Workflows

• Logs and Errors tabs: The expanded step log panel now shows separate Logs and Errors tabs, so standard output and stderr are no longer combined in a single stream.
• YAML validation states: A Pending validation state now covers the debounce gap after editing YAML and before validation runs. The Activate and Run buttons are disabled while validation is pending or in progress, and the Format YAML button can now format invalid YAML and permit a single trailing newline.
• All Runs timestamps and duration: The Scheduled, Created, and Duration columns in the All Runs list now show tooltips with exact values on hover, with the duration value emphasized for quicker scanning.
• Removed Paste from clipboard: The Paste from clipboard button has been removed from the workflow create editor.

Documentation sidebar

• Open in new tab: An Open in new tab control in the in-app Documentation sidebar lets you open the documentation in a new browser tab without closing the panel.

Bug fixes

• Fixed alias URL preview for cluster-style subdomains: The alias URL preview for app instances behind a cluster-style subdomain combined with an /instance/<id> path now correctly preserves the cluster subdomain and strips the instance path.

4.0.5 | May 27, 2026

New features and enhancements

Workflows

• Run input parameters: Triggering a workflow that declares run inputs now opens a parameters dialog to collect required values before the run starts, so no run starts with missing inputs.
• YAML editor enhancements: A Format YAML button tidies the document in place, a Documentation sidebar links to syntax references, examples, and getting-started guides, and a tooltip on the validation status indicator shows error and warning details on hover. App Documentation now opens in a new browser tab.

CLI & API Access

• Quick token generation: Clearly labeled Generate API Token actions for both the Platform API token and the App Store CLI token are now at the top of the CLI & API Access page, removing the need to scroll to start a token-generation flow.

Admin Center

• DAI Connector Config page: A new admin page lets administrators upload, list, view, and delete DAI connector configuration files.
• AIEM page stats and timeline: The AI Engines admin page now shows an engine-event timeline and summary stats cards. FW Management and MLOps gauge metric views are also updated.

AI Engine Manager

• Full resource name in Engine details: The Engine details view now displays the complete engine resource name, making it easier to copy or share the exact identifier.

Bug fixes

• Fixed DAI Engine Profile creation crash when updating Duration constraints: Duration values are now serialized in a valid protobuf Duration format, so saving an updated profile no longer crashes the page.
• Updated containerd to address a container security vulnerability.

4.0.4 | May 13, 2026

New features and enhancements

Workflows

• Full-page YAML editor: Workflow creation now opens a dedicated full-page view instead of a modal. New drafts start with a pre-populated id, and pasting YAML from your clipboard automatically rewrites the id when it conflicts with an existing workflow, so you can use an existing workflow as a starting point without manual edits. For more information, see Workflows.
• Manual and Scheduled run tabs: The "All Runs" view is now split into Manual and Scheduled tabs, making it faster to locate specific runs.
• Run details improvements: Retrying a run now navigates to the latest attempt automatically; run and job durations update live while jobs are in progress; and the dependency count on graph nodes displays more clearly.
• Single confirmation on save: Saving updated workflow YAML now shows one "Workflow activated successfully." notification instead of two separate messages.

AI Engine Manager

• Clearer Driverless AI license expiry message: The expiry warning now reads "The Driverless AI license has expired. Contact your administrator to renew." so users know who to contact to restore access.

Bug fixes

• Fixed jobs graph status for dependency nodes: Nodes referenced by instance or resource ID (for example, matrix jobs like sleep-10) now correctly show their actual status instead of appearing as missing placeholders.
• Updated Go, H2O CLI, and helm to address multiple security vulnerabilities.

4.0.3 | Apr 10, 2026

Bug fixes

• Addressed minor UI issues.
• Fixed a navigation bug where moving from lineage to parent directed users to the wrong version.

4.0.2 | Apr 10, 2026

New features and enhancements

• Workflow runs UX: The Runs tab now displays runs across all revisions rather than just the currently selected one. Jobs are ordered by dependency topology, and scrolling over the jobs graph no longer hijacks page scrolling.
• DAI license expiry warnings: Added a prominent warning banner on AI Engines pages and an inline license alert next to the Submit button. A confirmation modal now requires explicit acknowledgment if a license is expiring within 30 days or has already expired.
• Notebook Engine details: The AI Engine details panel now includes a "Notebook Image Info" block, displaying the image source, pull configuration, and audit fields directly in the UI.

Bug fixes

• Feature store join transformations: Fixed an issue where creating a feature set via a join would silently fail. Joins now submit a correct draft and register successfully.
• Admin visibility: Authorization checks for "list all" actions are now mapped to the correct top-level resource, ensuring administrators can reliably see all admin sections across environments.
