* **New features**
+ * Introduce memory allocation threads
+
+ When starting a QEMU guest, libvirt can now instruct QEMU to allocate
+ guest's memory in parallel. This may be handy when guest has large amounts
+ of memory.
+
* **Improvements**
* qemu: ``VIR_MIGRATE_PARAM_TLS_DESTINATION`` now works with non-shared storage migration
@@ -32,11 +38,56 @@ v8.2.0 (unreleased)
specify the overrides instead of relying on the argv passthrough of the
``-set`` qemu commandline option which no longer works with new qemu.
+ * libxl: Turn on user aliases
+
+ Users can now use so called user aliases for XEN domains.
+
+ * Implement support for FUSE3
+
+ The LXC driver uses fuse to overwrite some lines in ``/proc/meminfo``
+ inside containers so that they see correct amount of memory given to them.
+ The code was changed so that both ``fuse`` and ``fuse3`` are supported.
+
+ * Improve domain save/restore throughput
+
+ Code that's handling save or restore of QEMU domains was changed resulting
+ in better performance of I/O and thus shortening time needed for the operation.
+
* **Bug fixes**
* Both build and tests should now pass on Alpine Linux or any other
distribution with musl libc.
+ * virsh: Fix integer overflow in allocpages
+
+ On hosts which support hugepages larger than 1GiB ``virsh allocpages``
+ failed to accept them because of an integer overflow. This is now fixed.
+
+ * qemu: Fix segmentation fault in virDomainUndefineFlags
+
+ When a domain without any ``<loader/>`` was being undefined, libvirt has
+ crashed. This is now fixed.
+
+ * lxc: Fix unaligned reads of /proc/meminfo within a container
+
+ When /proc/meminfo was read in chunks smaller than the entire file, libvirt
+ would produce mangled output. While porting the code to FUSE3 this area was
+ reworked and the file can now be read with any granularity.
+
+ * qemu: Be less aggressive around cgroup_device_acl
+
+ A basic set of devices common to every domain can be set in ``qemu.conf``
+ via cgroup_device_acl knob. Devices from this set are allowed in CGroup and
+ created in domain private namespace for every domain. However, upon device
+ hotunplug it may have had happened that libvirt mistakenly denied a device
+ from this set and/or removed it from the namespace. For instance,
+ /dev/urandom was removed and denied in CGroup on RNG hotunplug.
+
+ * nodedev: trigger mdev device definition update on udev add and remove
+
+ When nodedev objects are added and removed mdev device definitions are
+ updated to report correct associated parent.
