Hi, As many of you surely know, upstream support for python 2.7 is ending in 2020. Someone else may fill the gap but by and large people have migrated to python3. sage has slowly been migrating to python 3 over the last couple of years and sage 9.0 (the next release) will be the first one which default to python3 (3.7 to be more precise).
With that being said I am not sure for how long, after the first of January 2020, Gentoo will support python 2.7. So I have decided that in Gentoo the next release of sage (9.0) will drop python 2.7. While upstream may cling to it for a bit longer I want to have a head start on the impeding removal of python 2.7 from the main tree. For people following sage-9999 (the next beta release of sage), the drop will occur in the next release (probably called 9.0.beta7). Cheers, François
