 - [#353](https://github.com/nf-core/mag/pull/353) - Added the busco_clean parameter to optionally clean each BUSCO directory after a successful
 - [#361](https://github.com/nf-core/mag/pull/361) - Added the skip_clipping parameter to skip read preprocessing with fastp or adapterremoval. Running the pipeline with skip_clipping, keep_phix and without specifying a host genome or fasta file skips the FASTQC_TRIMMED process.
 - [#365](https://github.com/nf-core/mag/pull/365) - Adds CONCOCT as an additional (optional) binning tool
+- [#366](https://github.com/nf-core/mag/pull/366) - Added CAT_SUMMARISE process and cat_official_taxonomy parameter.
