Quoting myself: """ para ipython-owner --- Hi, Is there some work on updating to ipython5? I did some initial work just to get a feeling on how it should be done, but did not yet check packages that (build?) requires ipython. I need it for sagemath 7.4 on rawhide. Previously I was doing some patches to make it work with ipython3, but the patch no longer work (worked last for sagemath 7.3), so, my current WIP sagemath 7.4 package is installing a bundled ipython 5.0.0. Thanks, Paulo """
I just opened this bug report as an "excuse" for possible issues for importing ipykernel, that at first only sagemath will use, and newer sagemath should (temporarily) bundle ipython 5. The quoted email above was sent 16 November.
