i think we have an issue about this but

https://github.com/scipy/oldest-supported-numpy

is there a reason we don't just use this?

[fangchenli]

we can remove the line about for python 3.7

[fangchenli]

is there a reason we don't just use this?

There is an open drift #43146

[jreback]

can you add a note about the cython change in 1.4 whatsnew

[jreback]

docs error should be fixed on master if you can rebase

[jreback]

@lithomas1 lgtm. happy to merge (its a draft), small question. and do you want to try to merge directly to 1.3.4? (and can fix the backport)?

[lithomas1]

Thanks for the ping. Its draft because I'm still working on integrating the test from #43146. 1.3.4 would be fine for this.

[lithomas1]

Okay, this looks working and the test from #43146 has been added.
@henryiii Can you take one last look? Thanks for all the help so far.

[henryiii]

Looks good to me.

I'd still recommend (not a blocker, even if I had the ability to block things :P ) using numpy>=1.21.0; python_version>='3.10'; given this is completely optional segment anyway, and could just as easily be written in a single line numpy>=1.18.5; there is no reason to make it intentionally harder to test on Python 3.11 alphas by not requiring numpy at all - why add something else that could be forgotten? The first Python 3.11 alpha became available via actions/setup-python today, by the way.

Edit: new version looks great. :)

this is only to work with py310. for older python, previous min of Cython is still ok?

We are backporting this PR? (if so will need to move release note and say that the minimum is for py310 only?)

[jreback]

yeah i think ok to move to 1.3.4, this is only a build requirement so ok changing (esp for 3.10) on backport

[simonjayhawkins]

Thanks @lithomas1

[simonjayhawkins]

@lithomas1 needs manual backport when you can

[simonjayhawkins]

@lithomas1 does this now close #43715?

[simonjayhawkins]

I think asv_bench/asv.conf.json needs to be updated too? (Are the benchmarks running?) Any why is environment.yml and requirements-dev.txt not updated?
