10 September 2013: Launch of new ad formats and interface updates. Advertisers won’t be able to upload images in the new formats until September 10. Ads already running as of September 10 in the existing formats will continue to run, even if they don’t conform to the new specs. We will also start rolling out the ability to target by individual placement (News Feed mobile, News Feed desktop, Right column) on this date. For Power Editor and API, this means adding the ability to select right column only for placement. For the ads create tool, it means allowing advertisers to opt out of ads in News Feed or the right column. We will start rolling out the Power Editor and API capabilities on September 10, then expand to the Ads Create tool in the following weeks.
