Old description:



New description:

 The _boundary attribute has been deprecated since 2013-12-08 in #15494.
 This
 ticket totally removes it fro the graph class.

 The branch fixes a small problem that went probably unnoticed in #15494:
 the
 function Graph.genus was using this attribute (and so has been raising
 warnings
 for one year) but there was no other way to give a list of vertices to the
 function. Consequently, this branch turns one of its boolean arguments
 into a
 list, so that this function can be used properly, i.e. without global
 variables.
