It seems that zoom level 15 is no longer the highest zoom level on Commons - did something change?

Did something just change with the zoom levels?
Hmm, maybe it's not brand new, but I'm sure that the maps in categories like https://commons.wikimedia.org/wiki/Category:Guarany_(Pra%C3%A7a_Ramos_de_Azevedo) were at least one more step zoomed in. Those use https://commons.wikimedia.org/wiki/Template:AutoMapZoom to determine the zoom level, and when I coded that up it seemed that 15 was the most zoomed-in you could get.
The short answer is no, we didn't change the highest zoom level. The only thing slightly related with auto positioned maps is the following task: https://phabricator.wikimedia.org/T158919.
