For some context, TodoMVC is like a Rosetta stone showing how different frameworks implement the same Todo app. The current ember example uses 1.0.0-rc1, has some bugs (with the console open, try editing a todo, deleting all its text, and hitting enter), and doesn’t fully implement the spec.
Here is my pull request. I would welcome some comments and feedback! It is currently split into two commits, one updating the libraries and the other with the new ember 1.0 changes. This is the meaty commit.
