Translate tab doesn't appear using

I'm trying to use 2.0.0 in a 4.3.5 Plone site.
But the "Translate" tab doesn't appear in my content (folders, pages, ...),
only in "Media" folder.

Do I need to make some extra configuration?

Thanks in advance

I had the same problem working with Plone 4.3.6. You must set the "Multilingual Support" behavior to your content types to make content translatable.
