Critical bug fixes​

GCS compose conflicts

  • Fixed concurrent compose operation conflicts in Google Cloud Storage.
  • When multiple Fusion instances compose the same target file concurrently (e.g., with Nextflow job arrays where all array jobs overwrite .exitcode), temporary objects created during composition could conflict.
  • Prevents conflicts when concurrent instances attempt to create, use, or delete the same temporary files.

Upgrade notes​

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