Comment (by SimonKing):
I created the [http://users.minet.uni-
jena.de/cohomology/p_group_cohomology-2.1.5.spkg current version 2.1.5] on
my laptop and tested on the computer in my office. Most tests passed.
Problems:
- It seems that since a while, web access during doctests is not possible.
It used to work, and the failing tests do work in interactive sessions. No
idea how that could be fixed; I guess it was caused by a change in the
doctest framework.
- There have still been deprecation warnings when unpickling old pickled
cohomology rings. Whether or not we will see the deprecation warning
depends on the user: If (s)he has old pickles, then the tests will fail.
If (s)he removes the old pickles before re-installing the package, then
the tests will work.
- There has been one error where a different homogeneous system of
parameters was found. Mathematically there is no substantial difference,
but it may be needed to change the expected output.
