There was a small change for those wanting to add own map sources (not documented as for now): there's a new line needed in definition, assigning the source to profile:

"profiles": ["mixed", "online"],

Also, I have tried to suggest a change in Polish translation; I have no transifex experience, so I hope nothing got destroyed in the process It was "Exit" -- translated as "Wyjście", but in road context it would be "Zjazd" or "Wyjazd".
