These are valid points, yet since maintaining Python2 site/kernel/version/whatever indefinitely is impossible and sooner or later we will have to break things, I am still not convinced that there is much benefit in delaying it as much as possible. I am, however, quite sure that the transition has to happen between the terms as much as possible. If Sage itself switches in the middle, then I'll just hold the public servers for a few months.
It is, however, possible to warn the users somehow, e.g. we can put some wording on the root page or even something under the output window (where we have "Help | Powered by SageMath" at the moment). Something to encourage people to write Python3 compatible code, be aware of the upcoming transition, and I can look into setting up a test server that will run current Sage in Python3 mode. More concrete (and actionable ;-)) ideas are very welcome, as well as pull requests! -- You received this message because you are subscribed to the Google Groups "sage-cell" group.
