XboxLiveAPI is always getting better. So here's what's new in the latest version, XboxLiveAPI 2.0. Have some ideas for new features? Help contribute.
For complete documentation of the syntax changes in 2.0, check out the API Documentation. In order to completely upgrade from 1.0, you will need to completely remove all old files, and upload the more recent ones, since 1.0 has been completely removed from the repository and API service.
