What's new in Ubuntu (Kinetic Kudu) 22.10

Oct 29, 2022
  • These release notes for Ubuntu 22.10 (Kinetic Kudu) provide an overview of the release and document the known issues with Ubuntu and its flavours.
  • Ubuntu 22.10 will be supported for 9 months until July 2023. If you need Long Term Support, it is recommended you use Ubuntu 22.04 LTS 410 instead.
  • NEW FEATURES IN 22.10:
  • Updated Packages:
  • Linux kernel:
  • Ubuntu 22.10 is shipped with the new 5.19 Linux kernel that brings the following (most relevant) features (in addition to many other new features, new drivers, improvements and fixes):
  • The new futex_waitv() syscall that can speed up games by letting them wait for multiple futexes with a single system call.
  • Support in the task scheduler for CPU clusters that share L2/L3 cache (spreading tasks between clusters will bring more memory bandwidth and decrease cache contention).
  • Support for Intel® AMX (Advanced Matrix Extensions) instructions.
  • CO-RE support that makes compiled BPF programs more portable.
  • A faster random number generator (entropy extractor switched from SHA1 to BLAKE2s).
  • Support for proactive reclaim in memory control groups.
  • Support for Intel® Trust Domain Extensions (TDX).
  • systemd v251.4:
  • The init system was updated to systemd v251.4. Please refer to the upstream changelog 103 for more information about individual features.
  • Toolchain Upgrades :hammer_and_wrench:
  • debuginfod support
  • Following the recent announcement 23 of our debuginfod instance 16, Ubuntu now automatically requests debug symbols from the service when GDB (or any other debuginfo-consuming application) is used. Please refer to the Ubuntu Server Guide on debuginfod 18 for more information.
  • Security Improvements:
  • AppArmor gained support for restricting access to unprivileged user namespaces. This allows a system administrator to configure their system so that only applications and services which are confined by an appropriate AppArmor profile can use this feature.
  • Base System:
  • Netplan v0.105 55 gained support for VXLAN, VRF and InfiniBand devices
  • Ubuntu Desktop:
  • The default audio server is now PipeWire instead of PulseAudio
