As of 3.7 [1], dict is guaranteed to preserve insertion order:

  the insertion-order preservation nature of dict
  objects has been declared to be an official part
  of the Python language spec.

However, at least one key part of the language reference [2] was not updated to reflect this:  "3.2. The standard type hierarchy" > "Mappings" > "Dictionaries".

Note that the library docs [3] *were* updated.
