Parmi les changements les plus notables de cette branche :<\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li><strong>C++20 est devenu le mode C++ par d\u00e9faut<\/strong> au lieu de GNU++17. Pour utiliser le comportement pr\u00e9c\u00e9dent, il est d\u00e9sormais n\u00e9cessaire de sp\u00e9cifier explicitement le param\u00e8tre correspondant -std=.
