@luixxiul This is a very minor change. I don't think we need QA for this (we can't even realistically verify until the texts are translated and imported), and I don't think it needs to be included in the release notes.

[luixxiul]

I could verify change by myself by doing l10n on Transifex so no worry

[luixxiul]

Also the issue can be named "more l10n done" etc on release notes if it is worth mentioning. At least this does not have to be excluded from the release note so Iabelled to include it

[cndouglas]

Fair enough. If/when we import the translations from Transifex, we can use Spanish to test (I just translated it there).
