Stable kernel 4.14.336
This is the LAST 4.14.y kernel to be released. It is now officially end-of-life. Do NOT use this kernel version anymore, please move to a newer one, as shown on the kernel.org releases page.
All users of the 4.14 kernel series must upgrade. But then, move to a newer release. If you are stuck at this version due to a vendor requiring it, go get support from that vendor for this obsolete kernel tree, as that is what you are paying them for :)

[$] The odd saga of CVE-2012-5639
Vcc: a Clang compiler for Vulkan
It’s exactly what the name implies: a clang-based compiler that outputs code that runs on Vulkan.
Vcc can be thought of as a GLSL and HLSL competitor, but the true intent of this project is to retire the concept of shading languages entirely. Unlike existing shading languages, Vcc makes a honest attempt to bring the entire C/C++ language family to Vulkan, which means implementing a number of previously unseen features in Vulkan shaders

Leemhuis: Regression tracking: state of the union early 2024
Top-priority will be "make regzbot more useful for kernel subsystem maintainers" from now on. My tracking efforts of course will continue, but everything except regressions in the current and the previous mainline cycle might not see much attention from my side. This refocusing also means that I won't work much on resolving some ambiguities around "how regressions are supposed to be handled" which lead to tension quite a few times. But all that should be for the best in the long term.
Shaw: Python 3.13 gets a JIT
Copy-and-patch was selected because the compilation from bytecodes to machine code is done as a set of “templates” that are then stitched together and patched at runtime with the correct values. This means that your average Python user isn’t running this complex JIT compiler architecture inside their Python runtime. Python writing it’s own IL and JIT would also be unreasonable since so many are available off-the-shelf like LLVMs and ryuJIT. But a full-JIT would require those being bundled with Python and all the added overheads. A copy-and-patch JIT only requires the LLVM JIT tools be installed on the machine where CPython is compiled from source, and for most people that means the machines of the CI that builds and packages CPython for python.org.

The 6.7 kernel has been released
End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we've ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release.
Some of the headline features in this release are: the removal of support for the Itanium architecture, the first part of the futex2 API, futex support in io_uring, the BPF exceptions mechanism, the bcachefs filesystem, the TCP authentication option, the kernel samepage merging smart scan mode, and networking support for the Landlock security module. See the LWN merge-window summaries (part 1, part 2) and the (in-progress) KernelNewbies 6.7 page for more information.

Computer science pioneer Niklaus Wirth passes away (ITWire)
Wirth is well-remembered for his pioneering work in programming languages and algorithms. For these achievements, he received the ACM Turing Award in 1984, inducted as a Fellow of the ACM in 1994, and a Fellow of the Computer History Museum in 2004.
They include, among many, being chief designer for the programming languages Euler (1965), PL360 (1966), ALGOL W (1968), Pascal (1970), Modula (1975), Modula-2 (1978), Oberon (1987), Oberon-2 (1991), and Oberon-07 (2007).
