       To CADO-NFS users,

we have discovered some inefficiency in CADO-NFS polynomial selection,
which affects the latest release (2.2.0). In short, some algebraic
polynomials generated have their leading coefficient not divisible by
the parameter 'incr' (usually one takes incr=60, which guarantees some
good root properties).

This is fixed in the development version, up from revision 7187eb9.

If you use CADO-NFS 2.2.0: to avoid this issue, please make sure that
both admin and adrange are divisible by incr.
