New submission from Lele Gaifax: Python 3.6+ is stricter about escaped sequences in string literals.
The documentation need some improvement to clarify the change: for example https://docs.python.org/3.6/library/re.html#re.sub first says that “Unknown escapes such as \& are left alone” then, in the “Changed in” section below, states that “[in Py3.6] Unknown escapes consisting of '\' and an ASCII letter now are errors”. When such changes are made, usually the documentation reports the “new”/“current” behaviour, and the history section mention when and how some detail changed.
