Functional programming languages have a long association with graphs. In the
1990s, it was even thought that parallel graph-reduction
architectures could make functional programming languages much faster than their
imperative counterparts. Alas, that prediction mostly failed to materialize.
Even though graphs are still used as a theoretical formalism in order to define
and optimize functional languages (such as Haskell’s

spineless tagless graph-machine), they are still mostly compiled down to the same old
non-parallel assembly code that every other language uses. Now, two
projects —

Bend and

Vine — have sprung up attempting to change that, and prove that
parallel graph reduction can be a useful technique for real programs.

The Xen Project has announced
the release of Xen 4.20. This release adds support for
AMD Zen 5 CPUs, improved compliance with the MISRA C standard,
work on PCI-passthrough on Arm, and more. Xen 4.20 also removes
support for Xeon
Phi CPUs, which were discontinued
in 2018. See the feature
list and release
notes for more information.

Version
136.0 of the Thunderbird Desktop mail client has been
released. The release includes a quick toggle for adapting messages to
dark mode, and a new “Appearance” setting to control message threading
and sorting order globally, as well as a number of bug fixes. See the
security
advisory for a full list of security vulnerabilities addressed in
Thunderbird 136.0.

Version
12.3 of Linux From
Scratch (LFS) has been released, along with Beyond Linux
From Scratch (BLFS) 12.3. LFS provides step-by-step instructions
on building a customized Linux system entirely from source, and BLFS
helps to extend an LFS installation into a more usable system. Notable
changes in this release include toolchain updates to GNU Binutils
2.44, GNU C Library (glibc) 2.41, and Linux 6.13.2. The Changelog
has a full list of changes since the previous stable release.
