In this case "label" means "displayed name".

In general, in case of map styles it is useful to search also at the 
development site.

For this style it is https://github.com/gravitystorm/openstreetmap-carto

Oleksiy,
Those two changes are indeed very technical and are not related to mapping.

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:

https://wiki.openstreetmap.org/wiki/Key:shop
https://wiki.openstreetmap.org/wiki/Shops
https://wiki.openstreetmap.org/wiki/Key:building

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'
browsers.

Best regards,

[OSM-talk] OpenStreetMap Carto release v4.22.0

[Paul Norman via talk]

Dear all,

Today, v4.22.0 of the OpenStreetMap Carto stylesheet (the default
stylesheet on the OSM website) has been released. Once changes are deployed
on the openstreetmap.org it will take couple of days before all tiles
show the new rendering.

Changes include

- Shop label fixes and use ST_PointOnSurface for building label placement

  This fixes some bugs and makes building label placement consistent 
with shop

  label placement.

- Use `cache-feature: true` to improve performance of layers with 
attachments


- Use retail colour fill on malls

- Drop `highway=steps` from zoom 13

  This makes step rendering consistent with footways

- Render `place=locality` from zoom 16

  This fits current usage of the tag and what it is normally tagged on.

- Render `natural=bay` from linear ways

- Render administrative boundary labels from relations only

- Stop rendering natural=marsh

  It is recommended marshes are tagged with `natural=wetland` + 
`wetland=marsh`


- Use a whitelist for barrier rendering, and render `historic=citywalls` 
like

  `barrier=city_wall`.

- Support new Tibetan font name

  Noto has renamed Noto Sans Tibetan to Noto Serif Tibetan. The old name is
  still supported.

- Code cleanups to increase reuse and improve consistency


Thanks to all the contributors for this release, including daveol and
btwhite92, new contributors, and jeisenbe, a new maintainer.

For a full list of commits, see
https://github.com/gravitystorm/openstreetmap-carto/compare/v4.21.0...v4.22.0

As always, we welcome any bug reports at
