Critical bug fixes​

Azure​

Azure Directory detection

• Fixed "Is a directory" errors in hierarchical namespace containers (Data Lake Gen2).
• Fixed files incorrectly treated as directories causing workflow failures.

General​

Context cancellation

• Fixed critical operations failing mid-execution due to FUSE context cancellation.
• Prevented data corruption, ghost files, and orphaned S3 objects.
• Operations now complete reliably despite client disconnections.

Symlink compaction deadlocks

• Fixed deadlock in entryService shutdown with symlink compaction.
• Ensured target directory population before compaction.

Other improvements​

General​

Reliability

• Fixed race condition in directory iteration.
• Fixed write lock acquisition condition reevaluation.
• Added comprehensive lock documentation.

Testing and CI

• Pinned Nextflow to 25.04.8.
• Updated license test certificates (40-year expiration).
• Added GPU tracer test coverage.

Upgrade notes​

Drop-in replacement for v2.5.x. No configuration changes required.

Feature updates and improvements​

Data Explorer​

• Added support for LakeFS Cloud in Data Explorer by enabling image preview and file upload functionality when using LakeFS Cloud as an S3-compatible storage provider.

Compute environments​

• Improved job failure handling in AWS Batch compute environments. Improved AWS Batch workflow behavior to automatically terminate unschedulable jobs instead of leaving them pending indefinitely, providing faster feedback when compute resources are insufficient for workflow requirements.
• Added the g6e instance family to the list of AWS instances with NVMe storage.

Bug fixes​

Workflows​

• Fixed an issue where plots and charts in MultiQC reports appeared as grey boxes instead of displaying correctly, ensuring all visualizations now render properly. MultiQC reports generated by pipeline runs now display complete quality control metrics and interactive charts without missing content.

Studios​

• Fixed an issue where YAML validation errors did not display immediately when importing Studio configurations from Git repositories, ensuring configuration issues are now visible as soon as the import completes.

Compute environments​

• Fixed an issue where AWS single VM compute environments could not pull container images from private Amazon ECR repositories, bringing them to feature parity with AWS Batch compute environments.

Launchpad​

• Fixed an issue with older pipeline launch records, where the system did not set the source type properly, resulting in the system failing to access the pipeline entity on launch.

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.4.18-amd64.json'
}

Feature updates and improvements​

Resource labels​

• Improved label inheritance when launching workflows via API to automatically apply predefined labels when omitting the labelIds field, aligning API functionality with the GUI and simplifying workflow relaunches.

Bug fixes​

Workflows​

• Fixed an issue where changing the compute environment during workflow resume incorrectly updated the work directory path, causing failures because the workflow could not access cached results from the original run. The work directory now correctly retains the original value when resuming workflows with different compute environments.

UI/UX​

• Fixed an issue where the settings button in the usage overview widget incorrectly displayed workspace permissions in organization context, and improved workspace settings visibility to dynamically show or hide based on user permissions.
• Fixed an issue where workspace settings buttons displayed incorrectly based on user permissions and context, ensuring the settings button now shows the appropriate organization or workspace settings based on the current view.

Pipelines​

• Fixed an issue where creator avatars did not display in the pipeline version details view due to a missing avatar URL conversion.

Feature updates and improvements​

General​

• Documented update regarding BuildKit support on Bottlerocket by @gavinelder in #897

Full changelog: https://github.com/seqeralabs/wave/compare/v1.26.1...v1.27.0

Feature updates and improvements​

Container building​

• Added CRAN package support for Wave container builds by @pditommaso in #874

Full changelog: https://github.com/seqeralabs/wave/compare/v1.27.0...v1.28.0

How to pin this version​

fusion {
  enabled = true
  containerConfigUrl = 'https://fusionfs.seqera.io/releases/v2.4.17-amd64.json'
}

Bug fixes​

General​

• Fixed lock with symlink compaction.

Feature updates and improvements​

Datasets​

• Added support for date-only formats in search queries, allowing you to search using simple dates (e.g., 2025-02-02) instead of full ISO-8601 datetime strings.

Pipelines​

• Added pipeline version numbers and descriptions to preconfigured onboarding pipelines, making it easier to understand what each pipeline does.

Bug fixes​

Data Explorer​

• Fixed an issue where filtering for Azure credentials in Data Explorer only returned one credential type instead of all three available Azure credential types.
• Fixed an issue where the Data Explorer link did not appear in Task View when configuring multiple AWS credentials with similar permissions in the workspace.

Compute environments​

• Fixed an issue where Seqera Compute environments did not apply proper EC2 instance type constraints, ensuring consistent compute environment behavior and preventing instance unavailability issues.

Launchpad​

• Fixed an issue where users could dismiss critical notifications about compute environment substitutions when relaunching pipelines, ensuring important status messages remain visible throughout the workflow.

• Priority test reliability: Improve TestBandwidthExecutor/PriorityExecution statistical reliability by increasing buffer and task counts.
• Directory operations: Ensure rmdir() properly fails on non-empty directories.
• License tests: Update test certificates to expire in 40 years (2065) to prevent test failures.
