Jean-Fran├žois Burnol submitted an update to the

                xintsession

package.

Version number: 0.4alpha 2021-11-01
License type: lppl1.3c

Summary description: Interactive computing sessions (fractions, floating points, polynomials)

Announcement text:
----------------------------------------------------------------------

Add &ROOTS interface to under-the-hood usage of the polexpr
facilities allowing to get all real roots of the given polynomial
to arbitrary precision (and all rational roots exactly).

Dubbed "alpha" simply because I hesitate about the names &ROOTS
and &REFINEROOTS, and whether to have a variant which does not
automatically look exactly for the rational roots, or a variant to
refine only one given root.  Also because I added the interface
rather quickly (all of the hard work having been already done at
the polexpr level).
