 - [#118](https://github.com/nf-core/phaseimpute/pull/118) - Explain how to customize arguments in the pipeline.
 - [#111](https://github.com/nf-core/phaseimpute/pull/111) - Add nf-test for all sbwf, wf, modules and functions.
 - [#131](https://github.com/nf-core/phaseimpute/pull/131) - Set normalisation as optional. Fix extension detection function. Add support for validation with vcf files. Concatenate vcf only if more than one file. Change `--phased` to `--phase` for consistency.
+- [#143](https://github.com/nf-core/phaseimpute/pull/143) - Improve contigs warning and error logging. The number of chromosomes contigs is summarized if above `max_chr_names`.
