Release Notes

pycountry/pycountry (pycountry)

v26.2.16

Compare Source

• Dropped support for end-of-life Pythons 3.8 and 3.9.

• Added explicit support for Python 3.13 and 3.14.

• Updated to iso-codes 4.20.1.

• Added support for matching initials in countries.search_fuzzy. For
  example, results for countries.search_fuzzy("UK") will now include
  GB (United Kingdom).

• Fixed subdivisions.add_entry and subdivisions.remove_entry, which
  would previously render the country_code index of subdivisions
  unusable causing subdivisions.get(country_code=...) to return a malformed
  result. Fixes issue #​281.
