+# v19.0
+
+This release has been tracked through the [v19.0
+project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/22).
+
+### Improved PTY handling for serial and `virtio-console`
+
+The PTY support for serial has been enhanced with improved buffering when the
+the PTY is not yet connected to. Using `virtio-console` with PTY now results in
+the console being resized if the PTY window is also resized.
+
+### PCI boot time optimisations
+
+Multiple optimisations have been made to the PCI handling resulting in
+significant improvements in the boot time of the guest.
+
+### Improved TDX support
+
+When using the latest TDVF firmware the ACPI tables created by the VMM are now
+exposed via the firmware to the guest. 
+
+### Live migration enhancements
+
+Live migration support has been enhanced to support migration with `virtio-mem`
+based memory hotplug and the `virtio-balloon` device now supports live
+migration.
+
+### `virtio-mem` support with `vfio-user`
+
+The use of `vfio-user` userspaces devices can now be used in conjunction with
+`virtio-mem` based memory hotplug and unplug.
+
+### AArch64 for `virtio-iommu`
+
+A paravirtualised IOMMU can now be used on the AArch64 platform.
+
+### Notable bug fixes
+
+* ACPI hotplugged memory is correctly restored after a live migration or
+  snapshot/restore (#3165)
+* Multiple devices from the same IOMMU group can be passed through via VFIO
+  (#3078 #3113)
+* Live migration with large blocks of memory was buggy due to an in issue in
+  the underlying crate (#3157)
