+1, since these are closed:

• Evaluate Cython 3.0 #17102
• DIS: Cython 3 perf regressions #27086

Since this is only a build dependency I would be inclined to bump.

+1 for using Cython>=3.0.8 as a build dependency.

Should we milestone it for 1.5?

If some of the PR above are bug fixes, then we would need to target for the bug fix release.

I'll submit a PR to bump the min version.

A bit confused. cython=3.0.8 doesn't seem to be on conda-forge: https://anaconda.org/conda-forge/cython/files

However, two weeks ago the 3.0.8 build PR was merged: conda-forge/cython-feedstock#133

Opened this to ask: conda-forge/cython-feedstock#134

Seems like the files have been uploaded quite recently:
https://anaconda.org/conda-forge/cython/files
I seem to remember there is some small delay (maybe 1-2 hours) between the upload and the fact they are visible by conda install

Ah right I am reading the issue you opened so there was indeed an issue which was fixed. Now files have been uploaded and there is this small delay to wait.

What do we do about anaconda main channel? (I have wanted to ditch that completely for a while).

cython=3.0.6 is the latest there.

What do we do about anaconda main channel?

Can we ignore them?

Can we ignore them?

I would love to. But a few of us insist on keeping main channel on the CI 😁 in #28284 I'm installing cython from pypi on those CI runs.

Thank you, @adrinjalali.
