Thank you for the release assembly and tagging, Mindy!  Ive activated CI for 
the mirageos-3-beta branch at:

  https://ci.ocaml.io/mirage/mirageos-3-beta/ref/heads/master

You can also find differential bulk build results with and without mirage-dev 
included at:

  https://ci.ocaml.io/mirage/opam-repository/ref/heads/bulk

The differences are:

datakit (0.8.0 -> dev~mirage) fails now
dog (0.2.1 -> 0.2.1) fails now
ezirmin (0.1.0 -> 0.1.0) fails now
jitsu-libxl (0.0.1 -> 0.0.1) broken before and now builds
mirage-block-xen (1.4.0 -> dev~mirage) broken before and now builds
mirage-console-xen (1.0.2 -> dev~mirage) fails now
mirage-entropy-xen (0.3.0 -> 0.3.0) fails now
mirage-git (1.6.0 -> 1.6.0) fails now
mirage-irmin (0.9.8 -> 0.9.8) fails now
mirage-net-solo5 (0.1.1 -> dev~mirage) fails now
mirage-net-xen (1.6.1 -> dev~mirage) still broken
mirage-qubes (0.3 -> dev~mirage) fails now
mirage-xen (2.6.0 -> dev~mirage) fails now
mirage-xen-minios (0.8.0 -> 0.8.0) fails now
mirage-xen-ocaml (2.6.0 -> dev~mirage) fails now
mirage-xen-posix (2.6.0 -> 2.6.0) fails now
qcow (0.7.0 -> dev~mirage) fails now
qcow-format (0.5.0 -> 0.5.0) fails now
session (0.3.0 -> dev~mirage) fails now
vhd-format (0.8.0 -> dev~mirage) fails now
vpnkit (0.0.0 -> 0.0.0) fails now
xenctrl (0.9.30 -> dev~mirage) broken before and now builds
datakit-ci (new dev~mirage) fails now
mirage-www (new dev~mirage) fails now
prometheus-app (new dev~mirage) fails now
shared-block-ring (new dev~mirage) fails now

Some of these failures need triage, but there are almost certainly a few 
genuine build failures in there. Any debugging or PRs fixing your libraries are 
most welcome.  I'll switch this testing over to the mirageos-3-beta branch on 
Monday.  I am also deploying the beta branch for live infrastructure as well, 
so we will move to Solo5 and Xen simultaneously as soon as everything is 
compiled and deployed.

regards
Anil
