+        </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.

+        <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.

+        <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.

+          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.

+        <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.

+        </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.

+        <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.

+        <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.
