  * Added Changes
    - update VCS-git to match the bionic branch
    - sdl2 is yet too unstable for the LTS Ubuntu release given the reports
      we still see upstream and in Debian - furthermore sdl2 isn't in main yet,
      so we revert related changes to stick with the proven for now:
      - 0fd25810 - do not build-depend on libx11-dev (libsdl2-dev already
                   depends on it)
      - 9594f820 - switch from sdl1.2 to sdl2 (#870025)
    - d/qemu-system-x86.README.Debian: document intention of nested being
      default is comfort, not full support
    - update Ubuntu machine types for qemu 2.11
    - qemu-guest-agent: freeze-hook fixes (LP: #1484990)
      - d/p/guest-agent-freeze-hook-skip-dpkg-artifacts.patch
      - d/qemu-guest-agent.install: provide /etc/qemu/fsfreeze-hook
      - d/qemu-guest-agent.dirs: provide /etc/qemu/fsfreeze-hook.d
    - Create and install pxe netboot images for KVM s390x (LP: #1732094)
      - d/rules enable install s390x-netboot.img
      - debian/patches/ubuntu/partial-SLOF-for-s390x-netboot-compilation.patch
    - d/control-in: enable RDMA support in qemu (LP: #1692476)
    - on s390x provide facility bits 81 (ppa15) and 82 (bpb) (LP: #1743560)
      - d/p/ubuntu/linux-headers-update-to-4.15-rc1.patch
      - d/p/ubuntu/linux-headers-update-4.15-rc9.patch
      - d/p/ubuntu/lp1743560-s390x-kvm-Handle-bpb-feature.patch
      - d/p/ubuntu/lp1743560-s390x-kvm-provide-stfle.81.patch
    - tolerate ipxe size change on migrations to >=18.04 (LP: #1713490)
      - d/p/ubuntu/pre-bionic-256k-ipxe-efi-roms.patch: old machine types
        reference 256k path
      - d/control: depend on ipxe-qemu-256k-compat-efi-roms to be able to
        handle incoming migrations from former releases.
    - d/control-in: enable seccomp on s390x
  * Dropped changes (no more needed):
    - Dropped VHOST_NET_ENABLED and KVM_HUGEPAGES from /etc/default/qemu-kvm
      The functionality is retained for upgraders, but is deprecated.
      Post 18.04 the implementation for these configurations will be removed.
  * Dropped changes (in Debian now):
    - ppc64[le] support
      - Enable seccomp for ppc64el
      - bump libseccomp-dev dependency, 2.3 is the minimum for ppc64
    - disable missing x32 architecture
    - d/rules: or32 is now named or1k (since 4a09d0bb)
    - d/qemu-system-common.docs: new paths since (ac06724a)
    - d/qemu-system-common.install: qmp-commands.txt removed, but replaced
      by qapi-schema.json which is already packaged (since 4d8bb958)
    - d/p/02_kfreebsd.patch: utimensat is no more optional upstream (Update
      to Debian patch to match qemu 2.10)
    - d/qemu-system-common.docs: adapt new path of live-block-operations.rst
      since 8508eee7
    - d/qemu-system-common.docs: adapt q35 config paths since 9ca019c1
    - make nios2/hppa not installed explicitly until further stablized
    - d/qemu-guest-agent.install: add the new guest agent reference man page
      qemu-ga-ref
    - d/qemu-system-common.install: add the now generated qapi/qmp reference
      along the qapi intro
    - d/not-installed: ignore further generated (since 56e8bdd4) files in
      dh_missing that are already provided in other formats qemu-doc,
      qemu-qmp-ref,qemu-ga-ref
  * Dropped changes (integrated upstream):
    - d/p/detect-ITS-and-skip-usage-on-older-kernel.patch to avoid crashes
      on arm64 when doing suspend/resume and reboots due to older kernels not
      supporting ITS (LP 1731051).
    - Apply linux-user-return-EINVAL-from-prctl-PR_-_SECCOMP.patch from
      James Cowgill to prevent qemu-user from forwarding prctl seccomp
      calls (LP 1726394)
    - update to upstream 2.10.1 point release (LP 1722808)
