December 2025: Delivered Head Job Resource Configuration via CLI for tower-cli, enabling --head-job-cpus and --head-job-memory to override head job resources when launching pipelines. This increases resource allocation flexibility and pipeline reliability in variable workloads, reducing manual environment tuning. No major bugs fixed this month; focused on delivering a robust, user-facing feature with clear CLI semantics. Key commit: c6d5bfb1dec0c9c2acb3b1fcb0177225ea876b8c

November 2025—Delivered substantial improvements to the Seqera Platform compatibility documentation. Completed extensive updates to the Platform Compatibility Matrix to include 25.2.3 and added missing stable releases for 24.1.x, 24.2.x, 25.1.x, and 25.2.x. Removed platform-specific suffixes from the Nextflow version column to clarify base Nextflow versions, while preserving nf-launcher suffixes in a separate column. Updated support statements to reference current major Platform versions (25.2.x, 25.1.x). These changes enhance accuracy, reduce customer upgrade risk, and improve onboarding for Platform installations.
