Fusion v2.6.10 fixes a regression introduced in v2.6.9 that failed successful snapshot tasks with exit code 174. If you run Fusion Snapshots on v2.6.9, upgrade.

How to pin this version​

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.6.10-amd64.json'
}

Bug fixes​

Fusion Snapshots​

• Fixed successful snapshot tasks failing with exit code 174 when the task deleted a temporary file it still had open.

Upgrade notes​

• Drop-in replacement for v2.6.9. No configuration changes required.
• If you pinned snapshot tasks to v2.6.8 to avoid the exit code 174 failures, you can unpin them.

Fusion v2.6.9 fixes three ways a healthy task could be lost in NFS service mode or on EC2: failed output uploads reported as success, a short EC2 instance metadata outage blocking S3 access, and remote I/O errors on a task relaunched from a clean start.

How to pin this version​

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.6.9-amd64.json'
}

Bug fixes​

NFS service mode​

• Fixed a task exiting with 0 when the final upload of its work directory failed. Fusion now retries the upload for about five minutes, then exits with 174. See Fusion exit codes.
• Fixed a Remote I/O error when a task relaunched from a clean start recreated a path the clean had removed.

AWS​

• Fixed a short gap in the EC2 instance metadata service leaving Fusion with anonymous S3 access for the rest of the task. If the work directory is still unreachable, Fusion exits with 173, which Intelligent Compute relocates to another host.

Dependencies​

• Updated dependencies and CI.

Upgrade notes​

• Drop-in replacement for v2.6.8. No configuration changes required.
• In NFS service mode, a task whose command succeeded but whose final work directory upload failed now exits with 174 instead of 0. A task whose command failed keeps its original exit code.
• On EC2, a host with no instance profile keeps using anonymous S3 access. If a host has an instance profile but no reachable instance metadata service and should use anonymous access, set AWS_EC2_METADATA_DISABLED=true.

Bug fixes​

Language features​

• Fixed formatter dropping the main: label when onComplete: or onError: is present by @ewels in #7346

General​

• Fixed BitbucketServerRepositoryProvider ignoring the token field by @jorgee in #7120

Dependencies​

• Bumped nf-amazon@3.4.6 by @pditommaso in 30cfdc47

Full changelog: https://github.com/nextflow-io/nextflow/releases/tag/v25.10.8

Feature updates and improvements​

Co-Scientist​

• Made Projects available in organization workspaces to roles with the Projects permission, which existing custom roles don't include.
• Added the Project workspace role, for a user who launches a project's pipelines, adds datasets, and reads run reports from the Projects view, without the workspace's Launchpad, Runs, Datasets, Compute, or Settings pages.
• Added a Projects permission category to custom roles.
• Surfaced proj_ labels as projects in Labels settings.
• Limited the launch picker on a project's Runs tab to pipelines that carry the project's label.

Pipelines​

• Added a Fusion version selector to the launch form, and limited both version lists to compatible versions.

Studios​

• Added Conda packages for custom container images under More settings.
• Shortened the browser tab title on the Studio details and connect pages to Studio: <name>.

Data Explorer​

• Added the bucket versioning state (Enabled, Suspended, Disabled, or Unknown) to the About data repository dialog for Amazon S3 and Google Cloud Storage data repositories.

Data lineage​

• Changed See in Data Explorer on the run Outputs tab to use the output directory from the run's lineage record.

Credentials​

• Added the Set up Workload Identity Federation in GCP panel to Google Workload Identity credentials created from the compute environment form.

Monitoring​

• Added a Quick launch action to the empty runs list.

Bug fixes​

Pipelines​

• Fixed the Add and Update buttons on the action and pipeline forms staying disabled after a pipeline revision failed to load.

Actions​

• Fixed a paused action that names a deleted pipeline being resumable instead of asking you to point it at a live pipeline.

Compute environments​

• Fixed Azure Batch Forge compute environment creation accepting a malformed container registry credential ID, or more than one.

Access control​

• Fixed selecting a template for a custom role not applying its permissions.

General​

• Fixed the Runs and All runs pages showing no results when opened or reloaded with a search filter in the URL.
• Fixed cancelled runs showing an empty Metrics tab.

Fusion v2.6.8 lets Intelligent Compute relaunch a task from a clean start after a failed snapshot restore, and fixes stale file handle errors on idle files in NFS service mode.

How to pin this version​

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.6.8-amd64.json'
}

Feature updates and improvements​

Fusion Snapshots​

• Added FUSION_SNAPSHOT_CLEAN_START. When it is set, Fusion cleans the work directory and removes leftover snapshot data before the task starts, so a task whose snapshot restore failed can be relaunched from scratch in the same work directory. Intelligent Compute sets it when it relaunches such a task.

Bug fixes​

NFS service mode​

• Fixed files and directories left idle during a task failing with a stale file handle error.

General​

• Fixed a spurious Check available filesystem space error printed every time a mount shut down.

Dependencies​

• Updated test and CI tooling and dependencies.

Upgrade notes​

• Drop-in replacement for v2.6.7. No configuration changes required.
• FUSION_SNAPSHOT_CLEAN_START applies to NFS service mode only, and you do not need to set it yourself. Without it, Fusion behaves as in v2.6.7.
• File handles in NFS service mode stay valid while the Fusion mount keeps running. They do not survive a restart of the mount.

Fusion v2.6.7 fixes a regression introduced in v2.6.6 that stopped retried tasks from starting when Fusion serves a work directory over NFS. If you run v2.6.6 in that configuration, upgrade.

How to pin this version​

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.6.7-amd64.json'
}

Bug fixes​

NFS service mode​

• Fixed retried tasks timing out with exit code 173 on every host after an interruption.
• Fixed a work directory emptied by an earlier attempt failing to prepare.
• Halved the storage listings needed to prepare a work directory.

Dependencies​

• Updated build tooling and dependencies.

Upgrade notes​

• Drop-in replacement for v2.6.6. No configuration changes required.
• The regression affects Fusion in NFS mode on v2.6.6 only. Earlier v2.6 releases are unaffected.
• Two limitations remain. A work directory reused without being cleaned is not swept, and leftover names can persist there. Snapshot restore in NFS mode is still under active work. Do not assume every restore path is covered.
