Good morning,

Thank you for the information.

I did not understand these two changes. I would like to see an example 
on the map or/and read a wiki article about the building label, the shop 
label, and the ST_PointOnSurface.

In the two following articles:


there is neither word "label", nor "ST_PointOnSurface". I would like to 
learn about it and, probably, use it.

As for layers with attachments, - I guess it does not concern mapping 
itself, but it's something related to a technical side of rendering. 
Probably, a layer has got some PNG image files, which are used in icons 
or displaying certain areas, and they will be cached in the visitors' 

Best regards,
Oleksiy (Alex-7 @ OSM)
