Hi! News from the Debian Xen team (well, that's still only Ian and me). We still have Xen 4.11 in Debian unstable and stable (Buster) now, but at this point I really want to start working on the preparations for the next Debian release which will happen in about a little bit less than a year from now.
So, the 4.14.0 release is a good moment to kick it off. In february 2020 Ian and I already spent a day to move the Debian packaging to 4.13, and the result has been laying around for a bit. Now I'm forwarding it to 4.14.0 and I really want to get this in Debian so users can start playing around with it and have enough time to either contribute new things (like cross-building for raspberry pi4!) etc. All the yolo WIP stuff without anything cleaned up is here: https://salsa.debian.org/xen-team/debian-xen/-/commits/knorrie/4.14 Unfortunately, it FTBFS in an unexpected way, since I cannot relate this to any of our additional patches or anything.

Knorrie P.S. The next big thing to fix in the packaging before it can go into Debian unstable is no usage of python 2 anywhere. I might ask some questions about that later.
