Historically Python version support was tied to OS’s within support windows. And the long tail there is usually RHEL. Those timelines are listed at https://access.redhat.com/product-life-cycles?product=Red%20Hat%20Enterprise%20Linux,OpenShift%20Container%20Platform%204.
RHEL 7 is still within extended support and 8 is within maintenance support. RHEL’s support window is an eternity. I think it imposes an excessive burden on Mercurial developers to support ancient Pythons for that long. So my suggestion would be for Mercurial to adopt Python’s EOL schedule. That would mean dropping 3.6 + 3.7 now and 3.8 after it hits EOL later this year. I would like to think the existence of Mercurial packages or an installer script installing its own (modern) Python would alleviate any concerns from end-users here. It’s not like these ancient distros are upgrading to a modern Mercurial in their first party packages. > On Jul 25, 2024, at 05:40, Raphaël Gomès <raphael.go...@octobus.net> wrote: > > Hi all, > > The question of removing support for Python 3.6 (and to a lesser extent 3.7) > is being raised more and more, while the burden of supporting it is > increasing. > > Does anyone still care about Python 3.6 or even Python 3.7?
