+### Added
+- `gecco.model.GeneTable` class to store gene coordinates independently of protein domains.
+
+### Changed
+- Refactored implementation of `load` and `dump` methods for `Table` classes into a dedicated base class.
+- `gecco run` and `gecco annotate` now output a gene table in addition to the feature and cluster tables.
+- `gecco train` expects a gene table instead of a GFF file for the gene coordinates.
