[virtio 1.3] Reminder: Feature freeze coming up on July 1st

[Cornelia Huck <cohuck@redhat.com>]

As outlined in
https://lists.oasis-open.org/archives/virtio/202304/msg00036.html ff.,
we'll soon start the process of getting version 1.3 of the virtio spec
released. As a first step, we'll enter feature freeze on July 1st. This
means:

***
By July 1st, all not yet integrated features that are targeting 1.3 need
to have at least a github issue open that is pointing to a patch (set)
on the list.
***

This should hopefully give us enough time to conclude voting for those
features before we enter change freeze on August 1st.
