What is Nextflow?

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

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.

What is FOSSA CLI?

Ecosystem-by-ecosystem parser coverage is the whole roadmap.

fossa-cli releases every one to two weeks, and nearly every change is about correctly reading one more package manager's metadata. In this window alone: pnpm lockfile handling refactored, npm v3 lockfiles taught target-level dependency scoping, Node workspaces matched when declared with a leading ./, sbt 1.4+ routed through DependencyTreePlugin, Conan list-valued licenses handled, and container scanning extended to /var/lib/dpkg/status.d.

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.

Ecosystem-by-ecosystem parser coverage is the whole roadmap.

◆ Current state

fossa-cli releases every one to two weeks, and nearly every change is about correctly reading one more package manager's metadata. In this window alone: pnpm lockfile handling refactored, npm v3 lockfiles taught target-level dependency scoping, Node workspaces matched when declared with a leading ./, sbt 1.4+ routed through DependencyTreePlugin, Conan list-valued licenses handled, and container scanning extended to /var/lib/dpkg/status.d.

◆ Where it's heading

This is the unglamorous core of dependency scanning: correctness depends on parsing every ecosystem's format exactly, and every ecosystem keeps changing its format. The work arrives as many small, ticket-tracked strategy fixes rather than architectural change, and it comes from a mix of regular maintainers and first-time contributors. Some releases exist only to cut a version.

◆ Prediction

Expect the same cadence of per-ecosystem parser fixes to continue, since that is what every release in this window consists of; nothing in the entries points to a structural change in how strategies are implemented.
