Note: For v11, there was a mistake in aggregating a number of A and A* variables from country-date to country-year by using the wrong aggregation method, most often using maximum instead of last or last instead of maximum per country-year. Most indices were not affected by this as they get calculated using country-date inputs. The following indices were affected and were recalculated for v11.1, the number of changed observations in comparison to v11 are in parenthesis: v2x_horacc (all), v2x_accountability (all), v2x_veracc (all), v2x_diagacc (all), v2x_divparctrl (45), v2x_feduni (8), v2x_regime (24), v2x_regime_amb (25), v2x_ex_confidence (17), v2x_ex_direlect (8), v2x_ex_hereditary (21), v2x_ex_military (52), v2x_ex_party (27). The affected A and A* variables were re-aggregated using the correct method for v11.1.
