Allow opening secondary drivers
</summary>
<description>
Up until now it was possible to connect to only hypervisor drivers
(e.g. qemu:///system, lxc:///, vbox:///system, and so on). The
internal drivers (like network driver, node device driver, etc.) were
hidden from users and users could use them only indirectly. Starting
with this release new connection URIs are accepted. For instance
network:///system, storage:///system and so on.

<summary>
Make port allocator global
</summary>
<description>
Up until now each driver had their own port allocator module. This
meant that info on port usage was not shared. Starting with this
release, the port allocator module is made global and therefore
drivers allocate ports from global pool.

qemu: Check for unsafe migration more thoroughly
</summary>
<description>
If a domain disk is stored on local filesystem (e.g. ext4) but is
not being migrated it is very likely that domain is not able to
run on destination. Regardless of share/cache mode.

qemu: Fix updating device with boot order
</summary>
<description>
Starting with 3.7.0 release updating any device with boot order would
fail with 'boot order X is already used by another device' while in
fact it was the very same device.

virlog: determine the hostname on startup CVE-2018-6764
</summary>
<description>
At later point it might not be possible or even safe to use
getaddrinfo(). It can in turn result in a load of NSS module which
can even be loaded from unsage guest filesystem and thus escape the
confinment of its container.

qemu: Rework vCPU statistics fetching
</summary>
<description>
Fetching vCPU statistics was very expensive because it lead to waking
up vCPU threads in QEMU and thus it degraded performance. The code
was reworked so that fetching statistics does not wake up halted
vCPUs.

qemu: unlink memory backing file on domain shutdown
</summary>
<description>
Depending on the filesystem where domain memory is stored, some files
might have been left behind. This is not a problem on hugetlbfs, but
it is a problem on regular filesystems like ext4.

qemu: Fix shutting down domains in parallel
</summary>
<description>
If multiple domains were being shut down in parallel, libvirtd might
have deadlocked.

nodedev: Update PCI mdev capabilities dynamically
</summary>
<description>
PCI devices may have other nested capabilities, like SRIOV and mdev
which depend on the device being plugged into the native vendor
driver. However, in case such a device is directly assigned to a guest
using VFIO driver, the device will naturally lose these capabilities
and libvirt needs to reflect that.
