* **New features**
* qemu: zero block detection for non-shared-storage migration
Users can now request that all-zero blocks are not transferred when migrating
non-shared disk data without actually enabling zero detection on the disk
itself. This allows sparsifying images during migration where the source
has no access to the allocation state of blocks at the cost of CPU overhead.
This feature is available via the ``--migrate-disks-detect-zeroes`` option
for ``virsh migrate`` or ``VIR_MIGRATE_PARAM_MIGRATE_DISKS_DETECT_ZEROES_ZEROES``
migration parameter. See the documentation for caveats.
* **Improvements**
* qemu: internal snapshot improvements
