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
