Adding a Spanish version

Ana's Half Hours Teach Book is written in English and published. Lucía adds its Spanish version, Libro del maestro: las medias horas.

Adding a language is a step of its own, and the new version starts from what its writer gives it. Lucía writes every field in Spanish; nothing is copied over from English. The Spanish version starts out not published, whatever the English version's status, and the English version isn't touched.

Try it: compare the two columns: find what's new, and what stayed the same.

Afterward, the Teach Book has two versions. The English one is just as it was, still published, with no new save in its history. The Spanish one is new and not published, so Spanish readers don't get it yet: they get nothing in Spanish, or the English Teach Book where their tools show English instead, until Ben publishes the Spanish version.
