Hi Nilson

sorry -- I was not following cython package recently so all kudos
to Stefano and other team members for taking good care of it under team
maintainership.

I think the best would have been to check existing bug reports and
follow up on them, thus to minimize traffic I immediately CCing
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1028157

Please follow up here and state your interest to see 3.0.0 in debian.

Note https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1028157#10

    The latest version of scipy, 1.11.1, needs Cython>=0.29.35
    but also declares Cython<3.0.

So we need first check with scipy on either it is ready for cython
3:

- upstream has (and I don't think ever had) no upper bound

    > grep Cython pyproject.toml
        "Cython>=0.29.18",

 in git log for scipy upstream I find last record for cython3 compat
 from v1.5.0rc1~75 in 2020!  So scipy was in sync with cython
 development

- for debian package upper bound was introduced in

    
https://salsa.debian.org/python-team/packages/scipy/-/commit/7a469e2435a01468b769f11c14f7e2a5c318fe4a

but no detailed reason provided.  so might have been general precaution. 

CCing Drew Parsons maintaining scipy -- may be he could recall the need
for upper bound or just make a verdict to drop that  upper bound?
