Sorry, no. This dist-upgrade has been the trickiest I've seen for a decade or so, and most of the glitches aren't really documented. #1) X starts needing xserver-xorg-input-libinput, which will be pulled in by default if you've got xserver-xorg-input-all installed, but not otherwise (symptoms: input stops working). There's a new item about libinput, but it basically fails to address this issue. #2) independently, startx stops working with similar symptoms, but nothing I've found makes it work again, regardless of what else I install (in particular, xserver-xorg-legacy makes no difference). The only solution I've found is to switch to lightdm (which might as well happen before the dist-upgrade). If nobody else is seeing this then I don't even know what to report a bug against. #3) after an upgrade, ifupdown is marked as automatically installed and no longer held in by dependencies, so things like aptitude want to uninstall it as junk. Fortunately I'd noticed this was likely to happen before I started doing upgrades, so I've never had my network crippled by this. I suggested some text about this in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864166#57 #4) at the end of the dist-upgrade needrestart restarts networking, which fails - the wifi interface gives errors as if I'd defined two gateway addresses. You can tell needrestart not to do this, but fortunately it's fixed by a reboot, and a reboot was the next step in the dist-upgrade anyway. However, it's easy to imagine ways this could combine with the other items on this list to be a real problem. I can't reproduce the issue outside the context of a dist-upgrade, so again I don't know where the bug is exactly, and if nobody else is seeing it then I don't know if it warrants being mentioned in the release-notes. It's possible that #2 amd #4 only hit me because I'm doing my trial upgrades on an old machine, and I'm not using a mainstream desktop environment (just fvwm). But I haven't heard anybody claiming to have done any bug-free upgrades, so it's hard to be confident. -- JBR with qualifications in linguistics, experience as a Debian sysadmin, and probably no clue about this particular package
