From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Release notes:

New features in 23.10 Updated Packages

add-apt-repository now adds PPAs as deb822 .sources files (Improvements to PPA management in 23.10 116).

Linux kernel :penguin:

Ubuntu 23.10 includes the new 6.5 Linux kernel that brings many new features.

Notable upstream changes:

Intel’s “Topology Aware Register and PM Capsule Interface” (interface that provides better power-management features).
arm64 permission-indirection extension (technology to set special memory permissions).
RISC-V now supports ACPI.
The Loongarch architecture now supports simultaneous multi-threading (SMT).
Support for unaccepted memory (protocol by which secure guest systems accept memory allocated by the host - Seeking an acceptable unaccepted memory policy 5.
The io_uring subsystem can now store the rings and submission queue in user-space memory.
Ability to mount a file system underneath an existing mount on the same mount point; useful in container scenarios (Merge tag ‘v6.5/vfs.mount’ of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs 5).
New cachestat() system call (query the page-cache state of files and directories).
Usual set of changes to support new hardware.

Notable Ubuntu-specific changes:

zstd compressed modules (LP: #2028568 11) to shorten boot time.
New Apparmor/Stacking LSM patch set.
Updated shiftfs patch set.
Enabled multi-gen LRU page reclaiming by default (LP: #2023629 1).

The network stack was updated to Netplan v0.107 3, introducing support for dummy and veth devices in addition to providing Python bindings to libnetplan in the python3-netplan package. Toolchain Upgrades :hammer_and_wrench:

Makes me nostalgic for when I got really excited for Ubuntu releases (circa 8.04-10.10 era)

That update where they switched everyone to that awful Unity DE was the breaking point for a lot of people I know.
