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 rgm?

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

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.

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

◆ Current state

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

◆ Where it's heading

Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.

◆ Prediction

The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
