Hi all!

Here is my proposal, about how to correctly update qcow2 specification
to introduce new field, keeping in mind currently existing images and
downstream Qemu instances.

Let's consider discussing from this.

I called it v7, as it's a continuation of
"[PATCH v6 0/3] qcow2: add zstd cluster compression". Still there are
actually only two preparing patches, so, if we like them (may be after
some resends) Denis's series should be rebased on these two patches.

Vladimir Sementsov-Ogievskiy (2):
  docs: improve qcow2 spec about extending image header
  docs: qcow2: introduce compression type feature
