Velocity5.0

Workflow orchestration engine for scalable and reproducible data pipelines

nextflow.io ↗

The workflow engine keeps shipping weekly, and more of each release is Seqera plumbing

◆Current state
Nextflow runs two tracks at once: stable 25.10.x and 26.04.x lines taking fixes and plugin bumps, and a monthly -edge series where features land first. Recent work splits between language and runtime correctness — typed process outputs, record types, config parser v2, job array handling — and a growing set of integration points with Seqera's commercial platform. GPU metrics now appear in the workflow-level execution summary.
◆Where it's heading
The engine is being wired progressively tighter to Seqera Platform. nf-tower has been consolidated into nf-seqera, a seqera:// filesystem provides data-links, the Seqera executor gained a per-task prediction model and a shellEnabled option, and Intelligent Compute scheduler run identifiers now propagate upward. In parallel the type system introduced with record types and typed outputs is still generating a steady stream of edge-case fixes, which is what a language change of that size costs.
◆Prediction
Expect the type-system fixes to keep arriving on the stable lines while the edge series continues adding Seqera executor capability, since that is where nearly all new configuration surface has appeared.

◆Recent moves

    25.10.7 fixes the v2 config parser and adds new GCP machine families

    A small stable-line release pairing config parser v2 corrections with support for the latest-generation Google Cloud machine families. The parser fixes matter more than they look — v2 is the config path the newer language work depends on.

    26.07.0-edge adds docker.cpuLimits and a Seqera provider config option

    Edge release adding a docker.cpuLimits config option, a graceful fallback when the array directive hits an unsupported executor, and seqera.executor.providerConfig. Also pulls Jackson forward twice to close high-severity deserialization CVEs.

    Version 26.04.6

    Two plugin version bumps, nf-seqera and nf-tower, and nothing else. A pure dependency roll on the 26.04 line.

    26.04.5 surfaces GPU metrics in the execution summary

    Adds GPU metrics to the workflow-level execution summary — useful for the accelerated pipelines Nextflow increasingly runs — alongside a flatMap tuple fix for dataflow values and propagation of the Seqera Intelligent Compute scheduler run identifier to Platform.

    26.06.0-edge folds nf-tower into nf-seqera

    Consolidates the nf-tower plugin into nf-seqera, simplifying what had been two overlapping integration paths into the commercial platform. Also fails with a clear error when Fusion is enabled without an access token, replacing a confusing failure mode.

    26.05.0-edge adds seqera:// data-links and per-task prediction

    The densest edge release in this window: seqera:// data-links support in the nf-tower filesystem, a per-task prediction model and shellEnabled option on the Seqera executor, workflow DAG reporting, Nextflow module info in lineage TaskRun entries, and a new nextflow logfile command.
