Hi,<br>
<br>
Thanks for pointing out a valid reason for keeping old Python versions. I know some projects still supporting as old as Python 3.2 or 2.6. Are there examples for Python 2.5 and 3.1?<br>

Well, upgrading from old Python versions is much easier than upgrading from old OS X versions. Due to Apple policies, new OS X versions do not work on old machines, and buying a new machine is apparently not an option for some people. In contrast, upgrading from Python 2.5 to 2.7 or 3.1 to 3.4+ takes almost no cost as CPython developers keep backward compatibility as best as they can do.<div dir="auto"><br></div><div dir="auto">Regarding "technical reasons" - there's one: old Python version does not build with OpenSSL 1.1, thus a blocker for upgrading the openssl port, and I don't think backporting fixes for openssl 1.1 is feasible as hundreds of lines should be patched.<br>
