Too Much Information?
Starting a discussion to ascertain why so much info was removed in the latest changes to this page. [To me] it makes the most sense to have more (potentially too much) information, than not enough. Developers are going to need to be aware of the changes to the API, and having this information available for search engines to index will only help the community transition to 3.0. IMO.
