Domino 6.2.1 (March 2026)

Additional component updates are available in ddlctl and fleetcommand-agent Release Notes.

Improvements

GenAI & LLM

This release delivers a broad set of enhancements to GenAI model management:

  • Added Azure and GCP support for GenAI model registration and deployment

  • Added AKS config support and NVIDIA environment variables for vLLM environments

  • Deprecated the legacy registerModel API V1

Workspace SSH / Domino Connect

  • Increased the SSH authentication timeout to 30 seconds

  • Added Azure Blob Storage support

  • Published recommended Azure architecture for the Workspace SSH feature

  • Added --doctor option for providing additional connection details

Bug fixes

GenAI & LLM

  • Fixed cross-project endpoint isolation — endpoints in one project can no longer access models from other projects

  • Resolved vLLM and model endpoint usage metrics not displaying correctly

  • Fixed UI issues including dynamic build logs, chart rendering, URL formatting in code snippets, and missing documentation links

Workspace SSH / Domino Connect

  • Fixed confusing errors when SSHD is not running or the run pod doesn’t exist

  • Resolved CLI requiring constant re-downloads

  • Fixed late version mismatch errors

  • Enhanced API access controls in Domino Connect

Keycloak deployments

  • Fixed an issue where multi-replica Keycloak deployments in large-scale environments could hit Infinispan cluster timeouts under load, causing login failures.

Known issues

  • After upgrading to version 6.1.1 from 6.1.0, Workspaces running in the local data plane with SSH enabled must be restarted once to retain SSH access.

  • Flows is only supported in Domino Cloud, AWS, and Azure. A future update will add support for Google Cloud and on-premises installs.

  • In Azure Blob Store deployments, Projects with many files may fail to sync through the Domino CLI. To work around this issue, do not disable file locking when prompted by Domino.

  • You cannot view the latest raw file if you click View Latest Raw File. In the navigation pane, go to Files and click a file to view its details.

  • If idle timeout is configured on a deployment, Domino may not recognize pages opened in spawned tabs (e.g., via Ctrl+Click) or outside of an iFrame as being active. Users may be unintentionally logged out despite activity in the spawned pages.

  • When uploading a large file to the Azure blob store by syncing a Workspace, you may encounter a Java Out of Memory error from Azure if the file/blob already exists. To work around this issue, use the Domino CLI to upload the file to the Project.

  • Model Monitoring data sources aren’t validated. If you enter an invalid bucket name and attempt to save, the entry will go through. However, you won’t be able to see metrics for that entry, because the name points to an invalid bucket.

  • When restarting an RStudio workspace with home directory persistence enabled, the user may see a notice stating that the previous session was abnormally terminated due to a crash. This notice is only due to how the new feature interacts with RStudio and does not result in any data loss.

  • Domino instances that make use of Azure Blob Storage may experience stalled Jobs within Projects with many large files.

  • If you attach a Git repository to a DFS Project that points to a tagged release, the tag won’t be honored when building a Domino endpoint in that Project. The build log will show an error similar to the following, and the model will be built using the default branch of your Git repository instead of the tagged branch:

    Jul 05 2023 14:36:27 -0500 #10 6.481 WARN [d.r.d.GitRepoUpdater] could not parse ref: v1.3.0 checking out default branch correlationId="iA2qWrYSLQ" thread="main"

    To work around this issue, use the branch name when building Domino endpoints instead of the release tag.

  • If an admin resets a user’s password, it invalidates all the user’s authentication tokens, including tokens used for long-running tasks like Jobs, Workspaces, or Apps. The user must create a new password, log back into Domino, and restart all executions. This also applies to CLI authentication; the user must re-login to their Domino CLI.

  • Data storage page fails to load when the dataplane agent in the remote data plane is scaled down to zero.

  • Nucleus Dispatcher restart hangs during Quartz Scheduler startup following a MongoDB replica set scale-down. As a workaround, manually remove the unavailable replica from the replica set using the Mongo CLI command.

  • During a 48-hour soak test, the nginx-ingress-controller pods exhibited a gradual increase in memory usage while handling heavy Domino Endpoint workloads. The cause is under investigation.

  • Agent monitoring dashboard retains only the current day’s data (charts have missing data and traces are gone). Historical data from previous days are lost, regardless of what time window is selected.
