Sage is changing the license for packages? I thought the Sage

the Sage distribution was GPLv2+?
Thanks,

We have numerous GPL version 2 only components too, so the truth is there is no
legal license for Sage.
To cut and past from the GPL2 in gfan
======================
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
=======================
Since some of packages will not have the "or later version" added into the
license, we can't distribute Sage as GPL 3 or even "GPL 2 or any later version",
since some of the components don't have the "or any later version".
IMHO, if you want to be totally legal, then you should not use Sage.
On the other hand, I personally don't see anything particularly immoral about
using Sage. I don't think the intenstion of the authors of the packages would be
to prevent their code being used in projects like Sage.
