In a file name pattern, <filename> is documented as the document's name
without its extension, but it expanded to the File Info title whenever the
document had one, so a saved my-logo.vectorcraft titled "Logo: final
version" exported as Logo--final-version__Artboard 1.png. The Full
Document file and the .zip took the same title.
Export for Screens and the dialog's Example line now take <filename> from
the document's file, as Save names it (save.rs), and fall back to the
title only for a document that has not been saved.
