Actually, better idea: I hereby give a blanket release ack for
anything in CHANGELOG.md that is committed by the end of Wednesday.
Whatever isn't ready by then I will look properly at. I expect us to
commit final docs updates early on Tuesday the 6th. So in practice I
think that means that any input from people who are away for Easter
needs to be finalised before the Easter weekend so that George and I
can get it properly into the tree.
Thanks,
Ian.

Looking at the log, the feature looks x86 only (at least the dom0 part).

Oh, interesting. So what about the following?

Sounds fine to me. Note that I haven't tried zstd-compressed for domu
Kernel on Arm.
Maybe the author (Jan) can confirm whether this was plumbed in common
libxc code?

Well, I've followed the model used for other compression methods. I have
no idea what this means or does not mean for Arm; in fact so far I was
under the impression that like in the hypervisor decompression support
was an x86-only feature, but from what you say I conclude I have been
wrong with this.

We support gzip for dom0. For guests, I am not entirely sure what the
