September 2025: nf-core/mag delivered production-ready enhancements to the assembly pipeline, expanded test configurations and snapshots, and strengthened CI reliability. Work focused on Metaeuk integration with GUNC enablement, robust test coverage for assembly_input variations, and ongoing maintenance of Nextflow references and changelog to support stable, auditable releases.

During August 2025, nf-core/modules and nf-core/mag delivered stability, testability, and maintainability improvements. The standout bug fix stabilised the CheckM2 database download by introducing a Zenodo metadata fetch helper and enabling the low-memory mode for the CHECKM2_PREDICT step, reducing failures and improving resource usage. In nf-core/mag, we completed a comprehensive test strategy including a complete test alternatives workflow, file exclusion from tests, and log checks to validate outputs. Substantial refactoring of local modules and workflows—replacing local pool_ modules with cat/fastq, reorganizing local modules and subworkflows, removing the local nanolyse module, and flattening local subworkflows—greatly improved maintainability and performance. Across both repos, ongoing code quality, documentation, and automation efforts strengthened reproducibility and release readiness. The month also featured broad ecosystem updates and QA work (BUSCO, metabat2, GTDB-Tk, FreeBayes, Genomad, bcftools, adapters/removal, dastool, pipelines/test configs, snapshots/MultiQC) to align with nf-core standards.
