 * Disentangle the `data/versions.csv` file by introducing `data/tyndp_versions.csv` ([#788](https://github.com/open-energy-transition/open-tyndp/pull/788)). All the TYNDP-specific version entries, as well as the `tyndp-archive` entries, are now tracked in this dedicated file. 
 
+* Fix quoting patterns for clarity ([#791](https://github.com/open-energy-transition/open-tyndp/pull/791)).
