qemu (1:2.12+dfsg-2) unstable; urgency=medium

   Since qemu 2.12, [G]UI display frontends can be built as modules.
   Debian creates new package, qemu-system-gui, which currently
   includes GTK3 support. This also switches display from SDL to GTK.
   Qemu-system-* packages recommends installing qemu-system-gui, so
   by default on upgrade you will have new package installed, and
   local GUI will continue to work. However, if you choose to not
   install recommended packages, you might consider installing
   qemu-system-gui package separately, if you need local GUI support
   as well. Without this package, qemu-system-* becomes "headless",
   and can be used on servers to reduce amount of dependencies -
   this way, no X11 stuff is needed by qemu-system anymore.

qemu (1:2.2+dfsg-6exp) unstable; urgency=medium

   Since Debian release 2.2+dfsg-6exp, a new package named qemu-block-extra
   has been created and some less frequently used block backends has been
   split out of main qemu-system binaries and from qemu-img binary to
   this new package.  The backends which has been split are:
     curl
     iscsi
     rbd (ceph/rados)
     ssh
   If you use any of these, please install qemu-block-extra package in
   addition to qemu-system-* or qemu-utils package, because without it
   these block backends won't work anymore.

qemu (2.0.0+dfsg-1) unstable; urgency=low

   qemu-system-* packages does not provide /usr/bin/qemu alternative
   anymore, and all various alternatives will be unregistered at new
   individual qemu-system packages install.  This is because different
   architectures are not really alternatives, and never has been.
   Historically, qemu emulated just one architecture, so the name "qemu"
   was used for the binary.  However when more architectures were added,
   the old name "qemu" was used as an alternative, pointing to one of
   the emulators.  Upstream does not use the name "qemu" for binaries
   for a long time.  If you have scripts using the old name "qemu"
   please update them to use the right qemu-system-* binary.
