+### Changed
+- Make the `genes.tsv` and `features.tsv` table contain all genes even when they come from a contig too short to be processed by the CRF sliding window.
+- Replaced the `--force-clusters-tsv` flag with a `--force-tsv` flag to force writing TSV tables even when no genes or clusters were found in `gecco run` or `gecco annotate`.
