They usually have very little harmful impact on python code. The pain in this case is that QGIS will not run on Windows 7 computers, because Python 3.9 does not support that OS, while 3.8 did.

Speaking as someone who works on a portable packaging system (pkgsrc), not particularly related to qgis: We tend to add new python versions more or less immediately (in parallel), change the default with due consideration, and then retire older versions when they are both out of support and no longer needed (in that anything that works with the old version also works with some newer version). It's quite common for python packages to fail with new 3.x versions, so we are somewhat shy about bumping the default version. We just a few months ago switched from 3.7 to 3.8, and that was probably overdue. At the time, some asked "why not 3.9" and the answer on looking was pretty clear: a fairly large number of packages did not build/work with 3.9. I am not sure it was 10%, but it was enough that having those packages be missing/broken with the default version seemed like a bigger minus than the positive benefit of a 3.8->3.9 move. So yes, for a given minor bump and a given package, the odds of trouble are fairly low, but the odds that a group of 100 packages has zero trouble is also pretty low, in my experience. Depending on packaging norms, the timeline involves not only the change necessary for 3.N++ to be accomodated, but then a release made. I expect pkgsrc will ask the "is it time for 3.9?" question again in April/May (we have quarterly cycle), and it feels like even odds if it will be time. So I am a bit surprised about the official windows installer moving to 3.9 already. (But I don't use Windows, and I build qgis from sources via pkgsrc, currently python 3.8.) signature.asc Description: PGP signature ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

It has not seemed to have caused any problems with my plugins.

[Qgis-user] Changes in Python versions on QGIS 3.18
Hello, I am not sure this is the appropriate mailing list to send this, but here it goes. I have noticed that QGIS 3.18 for Windows has shipped with Python 3.9, after having updated to 3.8 just a couple of versions ago. As a plugin developer, it becomes very difficult to track things and make sure plugins are up-to-date in the face of changing Python versions, especially when the move is to a bleeding edge version such as 3.9 right now. What channels should I be plugged into to learn about these changes and offer input before they happen? Is there such a channel?
