How do you save internal links during export ?

I’ m trying to save internal links during an export a Scrivener Project to a PDF or epub file.
Livehack tells me i’ ve got to make sure “Convert Scrivener links to HTML links” is checked under the HTML Settings tab.
Problem : this menu seems to have disapeared on v2,5.
Any suggestion ?

Well, PDF isn’t going to display the HTML Options pane. But ePub should be, and you definitely should be seeing the “Convert Scrivener Links to HTML links” option in 2.5. Just to clarify, I am referring to the option pane in the compiler—this isn’t a menu command.
