Dear all,

Hopefully, this is my last question for today.
Do you have any plan for 4.1? I see a bunch of commits with 4.1 in their messages.
I'm just wanted to know as it would be better for Sage to use a proper Singular version rather than some random commit.

We plan to have a Singular release at the end of september
(mainly waiting for,
which is in principle solved, and porting)
It is not yet clear if it will be 4.0.4
(with the changes currently described in
or if it will be 4.1.0 which additional introduces new types
(Ring: the current internal type coeffs,
Matrix: like "bigintmat", but with entries in any "Ring",
Number: the elements of "Ring", independent of the current (polynomial)
or both....

The main problem is the syntax: introduce a more mathematical notation
(a ring is a polynomial ring in Singular, Ring should be more gneral)
while keeping backward compatiblity.

Regards, Hans

Great, 4.0.4 or 4.1 would be equally good for Sage.
