This I would be okay with, and I have always said we should have maintenance branches, but the release manager doesn't want to do that so *shrug* -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

As far as I am concerned, the sooner py2 is dropped on the "main" branches, the better.

There will be a handful of folks who use (sage-9.x + Python 2) for whatever few values of x this will work for, but I agree with William and others that in nearly all cases just using 8.9 would suffice. Given that the period of official dual Python 2/Python 3 support is going to be a few months, not years, I see no harm in removing Python 2 support in Sage 9.1. In terms of helping users with thousands of lines of Python 2 based Sage code, trying to keep building Sage 8.9-the-distribution binaries for future OS releases as they come out is probably a lot more effective than working hard to push back the date that Python 2 support is dropped from Sage 9.x.

I only support python3 anymore on gentoo - because support for python2 ipython/jupyter as been removed from the main tree. I am the lucky one because I still have an ipython-5 I can pull as a dependency, most of my colleagues have to go ipython-7+ which is python3 only and requires heavy patching. Some interesting packages we may want to use that are python3 only and that will make our life difficult because we have to move forward regardless * ipython-7 * matplotlib-3 * sphinx-2 * numpy-1.17 * scipy-1.3+ The main person that has valid reason to want longer support for python2 is William. As he mentions, he has paying customers. At this point my only reasonable suggestion is to have a python2 compatibility branch for a while as sage-9.x while some of us plow on ahead without in sage-10.x. That’s unreasonable on the release manager unless someone step up to help. François -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

[sage-devel] drop python2 compatibility in 9.1 ?
Hello, I would like to suggest that the sooner we drop Python 2 support the better. We still need to handle the upgrade to ipython7 and the compatibility with python 3.8. All this will be made very difficult if we insist on maintaining a codebase that is both compatible with python 2 and python 3. So, please vote : Do you agree that sage release 9.1 (and most of the 9.1.betas) will not be kept compatible with Python 2 ?
