Wien tram 67: Fix the rail location around the stops Alaudagasse and Per-Albin-Hansson-Siedlung. Source: wien.at aerial imagery, which is not completely up to date, but definitely closer to what I've seen on site than what was drawn in OSM before.

Wien 10 (Oberlaa near bus stop "Oberlaa, Therme Wien"): Add name="Coskun Oberlaa" to the kebab place.

Wien 7 (Lindengasse 13-15): Fix the position of denn's Biomarkt, it's actually in the Lindengasse 15 house as correctly indicated by the address, not in the Lindengasse 9 house where the POI was erroneously located.

Wien 9 (Zimmermannschleife): Add tram stop Zimmermannplatz occasionally used (as the terminus) by shortened courses of trams 43, 5 or 33.

Wien 10 ("Access tower to U1 station", future metro station Oberlaa): Fix "tto" typo. It's questionable whether this belongs into the name= tag to begin with, but at least it's spelled correctly now.

Wien 10 (bus stop Oberlaa, Therme Wien): Add the new kebab stand.

Wien 10 (bus stop Oberlaa, Therme Wien): There is now some grass patch where the building used to stand, no current construction work noticeable at this site, so change to landuse=meadow.

Austria / Czech Republic: Fix incorrect "Dyje/March" name, the Dyje is the Thaya, not the March (and this segment is part of the Dyje/Thaya, not the Morava/March).

Wien bus 68A, 68B: Now operated by Gschwindl.

Wien 7 (Westbahnstraße 18): Delete Billa. This was a funny supermarket, divided into Westbahnstraße 15 and 18. Now only the Westbahnstraße 15 outlet is left, Westbahnstraße 18 has signs announcing the closure and sending customers to Westbahnstraße 15.

Wien 6 (Mariahilfer Straße 99): Delete DiTech. The original chain went bankrupt, and the new owners of the brand announced that they are not interested in this particular location.

Wien bus 41A: Now operated by Gschwindl (as of October 1). Also change name= from "41A" to "Bus 41A" for consistency.

Wien bus 60A: Now operated by Gschwindl (as of October 1).

Wien bus 19A: Now operated by Blaguss (as of October 1).

Wien 15 (Hütteldorfer Straße 95): Delete Niedermeyer, the chain does not exist anymore. (It went bankrupt.)

Wien 16 (Ottakringer Straße 186): Tag denn's Biomarkt (Filiale Ottakring).

Wien 7 (Neustiftgasse 127): Computer shop Peluga closed months ago, there is now the furniture shop Zeithammer at that address.

Wien tram 43 / bus N43 (stop Elterleinplatz): Tagging fixes.

Wien 3 (Fruëthstraße): The street signs on site spell this street as "Fruëthstraße" with a trema on the 'e'. It is named after Josef Fruëth (1745–1835).

Wien 1 (tfm): Make name= be the official German-language name, fix spelling of the int_name, add website.
