[Cython] Remove Py3.4 support in Cython 3.0?
Hi, I looked up where Python 3.4 is still being used. Ubuntu 14.04 – EOS 2019, EOL April 2022 Debian 8 – EOL Centos 6 – EOL Later distribution versions have newer CPythons: Ubuntu 16.04: Py3.5 (EOS April 2021, EOL 2024) Debian 9: Py3.5 (EOL June 2022) Centos 7: Py3.6 (EOL June 2024) I think we can safely drop Py3.4 support already for Cython 3.0. The advantage isn't big, since we still support Py2.7, but we can at least stop testing it, and start relying on the Py3.5 C-API for Py3. Given that Py3.5 is also going out of support in major Linux distributions within a year's time, I'd suggest we drop support for it in Cython 3.1, together with Py2 support, making the minimum version Py3.6. That would mean that we can start using f-strings, dict ordering, and what not. Any objections?

None from me - nobody on Ubuntu 14.04 (or similar) is going to get Cython 3 from their distribution. And if they're installing Cython manually then they can probably install a newer Python manually. Looking at the stats on PyPI (https://pypistats.org/packages/cython) the numbers of downloads for 3.4 are pretty small (a few hundred). And that's for the stable 0.29.x branch mainly I imagine. I doubt if they're the people that are looking to use the latest thing anyway. David On 14/08/2021 09:21, Stefan Behnel wrote: Hi, I looked up where Python 3.4 is still being used.

This should also have gone to cython-users (not just cython-devel), as it has the larger audience. Stefan Behnel wrote: Hi, I looked up where Python 3.4 is still being used.
