+# v20.0
+
+This release has been tracked through the [v20.0
+project](https://github.com/cloud-hypervisor/cloud-hypervisor/projects/23).
+
+### Multiple PCI segments support
+
+Cloud Hypervisor is no longer limited to 31 PCI devices. For both `x86_64` and
+`aarch64` architectures, it is now possible to create up to 16 PCI segments,
+increasing the total amount of supported PCI devices to 496.
+
+### CPU pinning
+
+For each vCPU, the user can define a limited set of host CPUs on which it is
+allowed to run. This can be useful when assigning a 1:1 mapping between host and
+guest resources, or when running a VM on a specific NUMA node.
+
+### Improved VFIO support
+
+Based on VFIO region capabilities, all regions can be memory mapped, limiting
+the amount of triggered VM exits, and therefore increasing the performance of
+the passthrough device.
+
+### Safer code
+
+Several sections containing unsafe Rust code have been replaced with safe
+alternatives, and multiple comments have been added to clarify why the remaining
+unsafe sections are safe to use.
+
+### Extended documentation
+
+The documentation related to VFIO has been updated while some new documents have
+been introduced to cover the usage of `--cpus` parameter as well as how to run
+Cloud Hypervisor on Intel TDX.
+
+### Notable bug fixes
+
+* Naturally align PCI BARs on relocation (#3244)
+* Fix panic in SIGWINCH listener thread when no seccomp filter set (#3338)
+* Use the tty raw mode implementation from libc (#3344)
+* Fix the emulation of register D for CMOS/RTC device (#3393)
