\400 -\777 now means the same thing in all d-quote
Prior to this patch, \400 - \777 meant something different in some
circumstances in regexes outside bracketed character classes. A
deprecated warning message has been in place since 5.10.1 when this
happens. Remove the warning, and bring the behavior into line with the
other double-quotish contexts. \400 - \777 now always means the same
thing as \x{100} - \x{1FF} (except when the octal forms are taken as
backreferences.)
