It’s been a long year since Yahoo's major search API changes. One of its popular offerings, the Yahoo BOSS API, was marked for transition to a paid service after integrating search results from Microsoft Bing. In April of this year, Yahoo BOSS V2 was released with pricing details, OAuth support and optional Advertising. Users have reacted positively to the changes and Yahoo has responded back with updates to BOSS V2 and a very short timeline to upgrade apps from V1.
