Hello, you can found now the newest Openlayers version under: http://toolserver.org/~osm/libs/openlayers/2.12/OpenLayers.js but I will not update "latest"-link to 2.12 until 2.13 is coming, because each map have to check and change some small things so that it works. The map inside Wikipedia (OSM-Gadget) is now also running at 2.12, advantage is the softer zooming.

Greetings Tim alias Kolossos
