Originally pushed to the sandbox in September, this initial release of the updated API includes support for the latest request syntax (e.g. the opensocial.IdSpec object), but other features such as lifecycle events and extended network distance are not yet available.
Please see the updated Developer's Guide and article list for more on developing using v0.8 and post any questions and bug sightings to the Developer Forum and issue tracker respectively.
