Changelog: Seqera Cloud

Version bump​

• Bumped Nextflow launcher to 25.04.x.

Bug fixes​

• Fixed an issue in Firefox where login resulted in an infinite loop in the browser.

Seqera Compute​

Seqera Compute is now in public preview. Seqera Compute is a fully managed, optimized compute environment which eliminates infrastructure complexity by automating environment setup, resource provisioning, scaling, and optimization.

Platform interface updates​

Pipeline run details​

The pipeline run details page has been refreshed and includes improvements such as:

• Clear, dynamic view of pipeline execution in real time via a progress bar.
• A dedicated Run info tab with a centralized view of run metadata and status details.
• Improved navigation tabs for Tasks, Logs, Metrics, and Containers.

New Seqera Platform sidebar​

The Platform top navigation has been replaced with a sidebar for improved navigation.

AWS Cloud compute environment​

The new AWS Cloud compute environment supports faster startup time, simplified configuration, and fewer AWS dependencies. Using this compute environment, Studios can now be launched on Spot instances. The AWS Cloud compute environment is best suited to run Studios and small to medium-sized pipelines. It offers more predictable compute pricing, given the fixed instance type. It spins up a standalone EC2 instance and executes a Nextflow pipeline or Studio session with a local executor on the EC2 machine. At the end of the execution, the instance is terminated.

API documentation improvements​

The Seqera Platform API documentation has been updated. Featuring overview pages with parameter and request body tables, categorized by Platform entity (compute environments, pipelines, etc.), the documentation now provides easier reference and detailed request examples.

Other new features and improvements​

• Fusion
  • Add Fusion snapshots to AWS Batch.
  • Enable DRAINING status for Spot instance reclamation. When an instance is in DRAINING status, no new task can be scheduled on it. See Configuring Amazon ECS Linux container instances to receive Spot Instance notices for more information.
  • AWS Cloud compute environment defaults to the public Seqera AMI if no AMI ID is specified during compute environment creation.
• Studios
  • Add Spot option for AWS Cloud compute environment.
• Support markdown rendering for Nextflow object field help_text and description properties.

Feature updates and improvements​

• Fusion
  • Add Fusion Snapshots support in AWS Batch compute environments, enabling Fusion to automatically restore jobs interrupted by AWS Spot instance reclamation. See Fusion Snapshots for more information.

Bug fixes​

• Fix container table pagination.
• Make task-level containers tab visible only when containers are available.

• Fix an issue where the Quick Launch form did not select the primary compute environment by default.

Feature updates and improvements​

• The default Azure Batch Ubuntu image has been updated with sku 22.04. This is to ensure there are no issues with the existing Azure Batch Ubuntu image (sku 20.04) which will be deprecated after April 23, 2025. See, https://github.com/Azure/Batch/issues/174 for more information about the deprecation.

Feature updates and improvements​

• Fixed a potential NullPointerException on code related to Google Batch, where the method is expected to return null.
• Fixed an issue where users were not able to remove the organization logo.

Feature updates and improvements​

• Studios
  • Add Studio session lifespan setting. This feature allows you to set a lifespan for a session, after which the session is stopped automatically.
  • Add Studios resource labels support. Workspace admins and owners can edit resource labels inherited from the compute environment and apply them to a Studio session. The edited resource labels associated with each session don’t affect the default resource labels associated with the compute environment.
• Free tier
  • Reduce the maximum number of organization members to 3.
  • Resource tracking in the Platform UI for improved management of free tier limits.
  • User disable/re-enable is now supported.

• Set ECS_CONTAINER_START_TIMEOUT to 10 minutes in the ECS settings used by AWS Batch CEs in order to prevent the error Task failed to start - DockerTimeoutError: Could not transition to started; timed out after waiting 3m0s.
• Upgrade to Angular 18

Bug fixes​

• Studios
  • Fixed an issue with searches for names containing special SQL wildcard characters (_, %).
  • Fixed an issue to ensure that the Maintain role is not able to change resource labels inherited from the selected compute environment when adding/starting a Studio.

Feature updates and improvements​

  • Add support for custom templates for input control options such as workspace visibility and session lifespan.
• Fusion
  • Default to Amazon Linux 2023 AMI when Fusion v2 is enabled.
  • Add support for Fusion licensing.
• (Enterprise only) Add a job to save usage metrics to files so usage data can be accessed and shared by users even when they’re not connected to License Manager.
• Implement FaviconService that changes the favicon based on pipeline run or Studio status.
• Increase accessTokenExpirationTime by 10% to always trigger a token refresh when Platform is open in a browser tab that isn't hibernated.
• Allow Nextflow configuration parameters with embedded references to other parameters to be shown verbatim.
• Extend zombie jobs detection on all workflows reaching one of the terminal states (SUCCEEDED, FAILED, CANCELLED).

Bug fixes​

• Fixed an additional reference to the mainScript parameter in the pipeline-info API response.
• Improved security of passthrough redirection on Platform authentication.

Breaking changes​

• Restore errorStrategy and maxRetries default Nextflow config for AWS and GCP launches. Platform will not overwrite existing error strategy coded in the pipeline repository.
• If you want to automatically retry on task failures (e.g., from spot reclamations), you will now need to explicitly set errorStrategy and maxRetries.
• Automatic spot retries in AWS and GCP need to be actively enabled. Alternatively the generic failure is handled at the Nextflow level.

You can revert to the default setting used in Nextflow prior to 24.10 with the following configuration options:

aws.batch.maxSpotAttempts = 5
google.batch.maxSpotAttempts = 5

Set task.maxRetries to a non-zero value to restore Platform to prior behaviour.

How do I retry Spot failures while making them visible?

There is no mechanism in Nextflow to specifically report Spot retries. However you can set process.maxRetries = 5 to retry all failures (including Spot reclamations) a specified number of times before failure.

Feature updates and improvements​

• Data Studios:
  • Added data studio API endpoints to the OpenAPI spec.
• New dynamic page title for easy bookmarking.
• Free tier:
  • New organization types added to allow free tier users to monitor their usage and limits.
• Restore errorStrategy default Nextflow config for AWS and GCP launches. The Nextflow job now correctly terminates after pipeline completion.
• Improved error messaging when pipeline info can't be fetched indicates whether the issue is due to a missing resource, or failed authentication due to expired credentials.
• Azure jobs are now automatically terminated after all tasks are complete.
• Send only added/updated run parameters when launching a pipeline. This includes all defaults and parameters passed during the launch.
