Great framework but are those all the changes in 3.0.0?
We haven't published the official 3.0 announcement yet, but you can find an overview of what's new on my Release Candidate/Beta blog posts:

The version of the specs published to knockoutjs.com didn't match the final release. I've just updated them. Please let us know if anything is still failing, preferably at https://github.com/knockout/knockout/issues
