• input is now a samplesheet to match samples to fastq files
• support technical replicates for a sample, so several fastq files, merged prior to alignment
• change trimmer to fastp and move to separate process
• params validation via a schema file
• report exact command lines and software versions into pipeline_info/ folder in the output directory
• modules generally accept a meta map inspired by nf-core for easy and standardized parsing of sample name, paired/single-end layout etc
• general overhaul in terms of code cleanup and structure
