Wien 10 (Forstamt, Triester Straße 114): Add missing building=office tag. office=* is NOT a replacement for building=*, so I readded the building key (but with a more precise value than the old building=yes).

Wien 1 (Heldenplatz/Volksgarten area): Import 3 drinking water fountains (amenity=drinking_water) whose existence and operability I have personally verified from wien.at OGD, also tag them with bottle=yes.

Wien 21 (Parkanlage Gitlbauergasse, Großfeldsiedlung): Add loc_name=Kürschnerwiese, used in media reports and even in local politics.

Wien 1: Delete 2 wrong drinking_water POIs added by changeset 71833872: one is clearly a duplicate, the other is at a wrong position (no drinking water there) and with a bogus name tag.

Wien 13 (Maxingpark): Tag the footway with name=Erwin-Strahl-Weg.

Weidlingbach (NÖ), Austria (Wienerwald Purkersdorf bis Klosterneuburg): Convert the intersecting inner rings to touching inner rings (lesser evil) by adding the intersection point to the meadow's polygon.

Wien/NÖ (Wienerwald Purkersdorf bis Klosterneuburg): Fix duplicate segments at the boundary of the multipolygon.

Wien 22 (Donauinsel near Ostbahnbrücke): Delete old toilets (POI last edited 2013) that were removed years ago. (They were already gone in the official map from 2016.)

Wien 23 (Harry-S.-Truman-Hof, Rudolf-Zeller-Gasse): Tag this building complex as a landuse=residential with name=Harry-S.-Truman-Hof enclosing the buildings.

Wien 21 (Karl-Seitz-Hof, Jedleseer Straße 66-94): Add name, addr:*, and wikipedia tags.

Wien 22 (Gedenkwald Aspern): Connect the wooden foot bridge to the nearby foot&cycleway so it is routable. It is clearly possible, intended, and legal to proceed there, as seen on site.

Wien 7 (Kirchengasse 18): Fix spelling of "Le Troquet", remove website tag (no longer active), add facebook tag.

Wien 7 (Kirchengasse 10): Fix name= tag of Karasan fast food.

Wien 7 (Kirchengasse 12): Tag dentist Dr. Barbara Matejka.

Wien 7 (Natraj, Neustiftgasse 50): Add smoking=outside tag (no smoking allowed inside, checked on site).

Wien 7 (Natraj, Neustiftgasse 50): Update website and opening_hours, reformat phone number.

Mödling, NÖ, Austria (toilets at Badstraße # Babenbergergasse): Fix access tag: access=public is not documented, use access=yes instead.

Wien 1, bus 2A, 3A (Rudolfsplatz): Move the platform to the correct side of the street.

Vösendorf, NÖ, Austria (Triester Straße south of # Anton Benya-Straße / bus stop Vösendorf Wienerberg): Add sidewalk=no tag, because the sidewalk abruptly ends at Anton Benya-Straße. (No foot=no tag because AFAIK it is not illegal to go on there by foot.)

Vösendorf, NÖ, Austria (Triester Straße): Map sidewalk situation between Vösendorf-Siebenhirten (Ketzergasse/Ortsstraße) and Vösendorf Wienerberg (Anton Benya-Straße).
