Re: obsolete information on the PARI/GP website

Hi Vincent,

Both problems should be fixed now.

I hadn't updated the HTML conversion in a while (can't do it automatically
since it breaks often and I don't want to fix it everyday...). I changed the
gphtml documentation converter to indicate the specific commit number in the
version, as in the GP header.

Thanks !

      K.B.

P.S. Note that GP 12.1 doesn't exist as a well defined object yet, although
the 'master' branch is made to "look like it" as much as possible.
