I think that does happen sometimes. In other cases it isn't possible, e.g., sometimes upgrades fail because the user changes (or breaks) their compiler between when they install sage-x and sage-y. In that case, there is nothing really to be done. You compared upgrading Sage to upgrading Firefox, but they are really different, since Firefox upgrades are *binaries*, whereas Sage are source-based. It would be neat to have binary based upgrades for Sage, but that would be a lot of work to implement, and I'm not going to do it today. -- William -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
