##### New features in 22.04 LTS
###### Updated Packages
###### Linux kernel 🐧
Ubuntu 22.04 LTS ships multiple optimized kernels on per-product basis:
- Ubuntu Desktop will automatically opt-into v5.17 kernel on the latest generations of certified devices (linux-oem-22.04)
- Ubuntu Desktop uses a rolling HWE kernel (linux-hwe-22.04) on all other generations of hardware. The rolling HWE kernel is based on the v5.15 kernel for 22.04.0 and 22.04.1 point releases
- Ubuntu Server defaults to a non-rolling LTS kernel v5.15 (linux-generic)
- Ubuntu Cloud and Devices use optimized kernels in collaboration with partners (v5.15+ with additional backports and features)
Additional optimized and certified kernel flavors will become available in Ubuntu 22.04 LTS in due course.
###### UDP disabled for NFS mounts
Since Ubuntu 20.10 (Groovy Gorilla), the kernel option CONFIG_NFS_DISABLE_UDP_SUPPORT=y is set and this disables using UDP as the transport for NFS mounts, regardless of NFS version.
In practice, if you try to use udp, you will get this error:
$ sudo mount f1:/storage /mnt -o udp mount.nfs: an incorrect mount option was specified
