text: The capital cities of the Dnipropetrovsk Oblast and Kirovohrad Oblast were renamed to Dnipro and Kropyvnytskyi in 2016 as part of a process of replacing Soviet toponyms. As the names of the oblasts are mentioned in the Ukrainian Constitution changing them requires a complicated and lengthy process, thus as of 2024 the two oblasts still formally retain their Soviet names.
