I ended up adding the date of the commit obsoleting the function:

% grep Obsolete: **/*(.)  | sort -rk 2

N.B. pari-2.7.0 was released on 2014-03-24
     pari-2.5.0 was released on 2011-06-22
     pari-2.3.0 was released on 2006-05-19

It would make sense to actually remove functions that became obsolete
long ago (before 2.5.0, say ?)

Cheers,
