Is the word versão the same in Brazilian and European Portuguese?

Yes. The only differences between Brazilian and Continental Portuguese regarding the word "versão" are in pronunciation.

The spelling, grammar, and fundamental meaning of the word are identical in both dialects. The difference lies in the phonetic realization:

• Pronunciation: In Brazilian Portuguese, the nasal diphthong "-ão" is typically pronounced with a more open and resonant sound, and the rhythm of the word is more melodic. In Continental Portuguese, the vowels are often more closed or "swallowed" (vowel reduction), and the pronunciation is more stress-timed, which can make the nasal sound seem shorter or more clipped to a Brazilian ear.
• Contextual Vocabulary: While "versão" itself does not change, the words surrounding it often do. For example, when talking about a software "version," a Brazilian will use "aplicativo" (app), whereas a Portuguese person will use "aplicação."
