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 Strimzi?

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

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.

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

◆ Current state

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

◆ Where it's heading

Post-1.0 Strimzi is spending its cycles on how the operator manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has gone alpha to GA and is now always on, and 1.2.0 changes install-time defaults toward Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens. A second candidate carrying one logging fix says the cycle is converging rather than still absorbing change — the CRD v1-only requirement from 1.0.0 remains the loudest thing in every release body.

◆ Prediction

Expect 1.2.0 final shortly with no further candidates, and the next cycle to advance one of the open feature gates — UseBackgroundPodDeletion is the likeliest to move from alpha to beta.
