A new ``VIR_MIGRATE_POSTCOPY_RESUME`` flag (``virsh migrate --postcopy-resume``)
was introduced for recovering from a failed post-copy migration.
+ * Introduce thread_pool_min and thread_pool_max attributes to IOThread
+
+ New attributes ``thread_pool_min`` and ``thread_pool_max`` were introduced
+ to ``<iothread/>`` as well as new ``<defaultiothread/>`` element with the
+ same attributes. This way it's possible to instruct QEMU to spawn enough
+ worker threads for an IOThread upfront, resulting in predictable time
+ needed to process an I/O requests.
+
* **Improvements**
+ * Define a TFTP server without a DHCP server in network configuration
+
+ It's now possible to define a network with no DHCP server but with a TFTP
+ server. This may be useful when DHCP service is provided by other entity on
+ the network than libvirt spawned dnsmasq.
+
* **Bug fixes**
+ * qemu: Restore label to temp file in qemuDomainScreenshot()
+
+ When virDomainScreenshot() is called, libvirt instructs QEMU to save the
+ screenshot into a temporary file. This file needs to be labelled correctly,
+ so that QEMU can access it. And since the file is temporary (it's deleted
+ after the screenshot was taken) the corresponding label restore was
+ missing. This proven to be problematic for profile based models, like
+ AppArmor, where the temporary files were added into the profile but never
+ removed, which resulted in longer profile recalculation times.
+
+ * qemuBuildInterfaceConnect: Initialize @tapfd array
+
+ Due to an uninitialized array, unsuccessful attempt to start a guest with
+ an ``<interface/>`` might have resulted in closing of a random FD and thus
+ sudden disconnect of a client or other random failures.
