I assume from the phrasing of your question that you're talking about how local results are incorporated in the regular organic SERPs. Is this correct?
I'm not seeing anything different, but Google has been testing many variants, so it's quite possible you saw something change. Can you describe what you were seeing previously, and what you're seeing today?
For what kind of search? Searched with or without placename?
Eg... - a term that is likely to refer to a brick and mortar local business (eg, "pizza" or "cityname pizza")... - a very general word like "electronics", that, without cityname, might refer to many different things, including local businesses... - a term that might be listed both in geo-directories and in local listings (eg, "cityname hotels").
When I search for "X in city" I'm seeing the natural results, but under each listing is a address and the thumbtack to a map. Previously, they listed local results in a separate section at the top of the page. Now they have blended the regular serps with the local information.
