Monthly updates to GeoNames data are incorporated into our databases as we
refresh them. Above you will find a CSV report of these changes as they apply to
English place names for the month of October as they relate to the following
fields:

- `geoname_id`
- `country_name`
- `country_code`
- `city_name`
- `subdivision_1_iso_code`
- `subdivision_2_iso_code`

Note that the values for the `old_` and `new_` columns for a given field only
differ for the field defined in the `diff_in` column.

\* \* Due to some irregularities in the data, we elected not to update GeoNames
data in August 2025 through September 2025. These issues have now been resolved
and we are resuming regular GeoNames updates. As a result, this month's GeoNames
update contains a larger number of differences than typical for a monthly
update. These changes are expected.
