Release v4.12.0

Done:

• New openstreetmap-carto release, v4.12.0 openstreetmap/chef#168

It looks like there is some performance problem, at least on low zoom levels:

openstreetmap/chef#168 (comment)

Could anybody test it? Since this is low zoom, it doesn't sound like road rendering code, but it's strange, since the global change #2874 should rather increase speed, so I'm not sure what's the problem.

This is the release containing subpixel accuracy, right? I had expected a significant performance improvement from that.

Anything else that could possibly cause this?

@pnorman The performance degradation you received a report of, was this with the new or old indexes?

We've released and #3280 covers the regression
