 - Summary processes don't modify the input file anymore, allowing resuming these processes ([#66](https://github.com/nf-core/crisprseq/pull/66))
 - Do not stash unexistent files, use empty lists instead. Fixes AWS tests ([#67](https://github.com/nf-core/crisprseq/pull/67))
+- Rename process `merging_summary` to `preprocessing_summary` to improve clarity ([#69](https://github.com/nf-core/crisprseq/pull/69))
