## New pipeline first releases 🎉

These pipelines just had their very first release.

- [nf-core/proteinannotator](https://nf-co.re/proteinannotator) v1.0.0 — Generation of sequence-level annotations for amino acid sequences
- [nf-core/seqinspector](https://nf-co.re/seqinspector) v1.0.0 — Dedicated QC-only pipeline for sequencing data. The pipeline will run a (potentially large) set of QC tools and can output global and group specific Multiqc reports. The pipeline is targeting core facilities or research groups with larger sequencing throughput.
