There used to bee two differnt orthographic dictionaries,
both called “Duden”:
► The Duden from Leipzig (DDR) had a captal “ß”, on the cover page
   of its 1957 edition.
► The Duden from Mannheim (FRG) never has featured a captal “ß”, IIRC.

Neither Duden has been anything like an “official version” – never ever.
Until 1996, the only official German orthography was somewhat loosely
defined by a common decision of the Ministers of Education of the FRG,
with an additional remark saying: “In case of doubt, the spelling of the
latest edition of the Duden (i. e. the Mannheim version) will take

Nowadays, the official version of the orthographic rules
can be found in:
the Uppercase-ß rule, particularily, is discussed in
under §25(E3); the latest version of the rule reads thusly:
> E3: Bei Schreibung mit Großbuchstaben schreibt man SS.
> Daneben ist auch die Verwendung des Großbuchstabens ẞ

which means:
   When writing in all-caps, you write SS.
   Alternatively, the capital ẞ may be used.

So, the normal upper-case equivalent of German sharp-S
still is the double-S. The recently introduced capital sharp-S
is an optional alternative, but not the normal way of
uppercasing the sharp-S.
