- minimum pandas version = 1.0
- The classifications for the EU are now based on names (EU27, EU15,
...) - the years have been removed (Brexit had made this necessary).
- The output of the class level attributes and methods for the
classifications (e.g. coco.OECD or coco.EXIO3as()) has changed
- The standard output of the command line changed from ISO3 to short
names, pass --to=ISO3 for the previous behaviour

Classifications

- Added EU12, EU15, EU25, EU27_2007, EU28 and EU27 classification.
This follows the names as explained here
