In the first page of dictionary functions, why does 8:64 come before the rest in the squares example?

The newest version of Python indeed introduces ordered dictionaries as a new class. However, standard dictionaries are still unordered. The output when printing is performance-optimized and stable within an execution (if unmodified).
For standard dictionaries order is irrelevant, though.

I think that is because order is not always preserved in Python 3.5's dictionaries (but it is in the brand new Python 3.6)

OrderdDict is available in the collections module since Python 2, I think.
The order in standard dict is still not guaranteed, but it is more often ordered than in 3.5. That's not a new class, just a new implementation
