What

Updates two countries to their official ISO 3166 / UN short English names, and aligns the Czech native to its matching short form:

Code name (before → after) native (before → after)
CZ Czech Republic → Czechia Česká republika → Česko
CV Cape Verde → Cabo Verde already Cabo Verde (no change)

Why

Consistency with the short-name policy already applied to Türkiye, Kyiv, Eswatini, and North Macedonia. "Czechia" (ISO/UN since 2016) and "Cabo Verde" (ISO/UN since 2013) are the current official English short names.

ISO 3166 defines names only in English and French — it has no native-language field — so native is the dataset's own field. Česko is the official Czech short form (the native equivalent of "Czechia"), chosen to match the short English name and the dataset's short-native convention (e.g. Germany/Deutschland). CV native was already the short, untranslated Cabo Verde.

⚠️ Behavior change (reverse name lookup)

getCountryCode() matches on name/native, so the old strings no longer resolve:

getCountryCode('Czech Republic')   // false (was 'CZ')
getCountryCode('Česká republika')  // false (was 'CZ')
getCountryCode('Cape Verde')       // false (was 'CV')

getCountryCode('Czechia')          // 'CZ'
getCountryCode('Česko')            // 'CZ'
getCountryCode('Cabo Verde')       // 'CV'

Worth a changelog note. Shipping in the same minor as the currency data updates.

Sources

Official ISO 3166 / UN short names — not arbitrary edits, and consistent with names the dataset already uses for the same reason (e.g. Türkiye per ISO 3166).

CZ → "Czechia" / "Česko" — "Czechia" registered in UN UNTERM/UNGEGN (5 Jul 2016) and added to ISO 3166 (Sep 2016), alongside the formal "the Czech Republic". ISO carries only the English/French name; the UN recognises Česko (short) / Česká republika (formal) as the Czech names:

CV → "Cabo Verde" — the Republic of Cabo Verde asked the UN (24 Oct 2013) to use "Cabo Verde" in all official languages, untranslated; ISO 3166 follows UN usage:

Walkthrough

Two country display names are updated in packages/countries/src/data/countries.ts. The CV entry's name field changes from "Cape Verde" to "Cabo Verde", and the CZ entry's name field changes from "Czech Republic" to "Czechia". No structural changes, no other fields modified.

Poem

🐇 Two names set right, a small but true fix,
Cape Verde now Cabo, no more old tricks.
Czech Republic? Czechia is the name!
The dataset grows wiser, the world stays the same.
Hop hop, the data aligns — what a wonderful game! 🌍
