Now that all of Dresden has voted too, the Bundeswahlleiter has the updated results for all parties, nationally,
HERE.
It includes all the smaller parties, which haven't been mentioned much here yet.
The only ones among them that really made a dent were those of the far right. The neo-nazi NPD got 1,6% of the vote - compared to just 0,5% last time round. The Republikaner staid stagnant at 0,6%.
Beyond that, there are Die Graue, The Greys, a party for the elderly; and the Familien-Partei, the Family Party, which is of rather non-political, centrist bent and in the past scored some local successes, for example in Brandenburg. Both of them gained some and now received 0,4% of the vote.
