+---
+This release has been tracked in our [roadmap
+project](https://github.com/orgs/cloud-hypervisor/projects/6) as iteration
+v39.0. The following user visible changes have been made:
+
+### Variable Sizing of PCI Apertures for Segments
+
+It is now possible to use `--pci-segment` to adjust the aperture size that
+devices 32-bit and 64-bit PCI device BARs will be allocated from. Previously
+the address space was equally distributed across all the segments which may
+leave insufficient space for devices that require a large 32-bit space. With
+this change the weighting per segment can be adjusted. (#6387)
+
+### Direct Booting with bzImages
+
+Support for directly booting Linux from bzImages has been added.(#6200)

+configuration of device P2P support with NVIDIA GPUs. (#6235)
