Tomorrow the Linux 6.6 kernel is expected to be released as stable unless Linus Torvalds has last minute reservations and decides to extend the cycle by an extra week. While there were many last minute fixes this week, the changes don't appear to be too scary or invasive. In any event the Linux 6.6 kernel is bringing some exciting features.

Guardrails have been in place where the Firefox browser has enabled Wayland by default (when running on recent GTK versions) but as of today that code has been removed... Firefox will try to move forward with stable releases where Wayland will ship by default!

KDE developer Nate Graham is out with his usual weekly recap highlighting all of the interesting accomplishments for this open-source desktop for the past week. But with not having posted last weekend, this edition highlights the many achievements made by the KDE camp over the past two weeks.

Less than twenty-four hours after Bcachefs was submitted for Linux 6.7, this new open-source file-system has been successfully merged for this next kernel version.

Overnight the mainline Linux kernel has retired support for Intel Itanium (IA-64) processors.

The ReactOS project today published their latest newesletter that outlines development progress made in recent months for this open-source operating system project striving for binary compatibility with Windows device drivers and application/user-space software.

It's been an exciting week in the KDE space as along with releasing Plasma 6.0 Alpha, they have also committed to shipping Plasma 6.0 with the Wayland session being enabled by default.

In addition to the many x86/x86_64 and AArch64 improvements this round for Linux 6.7, on the RISC-V architecture side are some exciting kernel advancements too.

The latest software offering announced today by Canonical with an enterprise focus and their hopes of driving new Ubuntu Pro and support subscriptions is MicroCloud. Their MicroCloud software aims to make it easy to deploy a private cloud that is a "fully functional cloud in minutes" atop Ubuntu Linux.

While micro-architecture specific optimizations are rather common place within the Linux x86_64 kernel for various Intel and AMD CPU families with various performance tricks, the ARM64 Linux kernel maintainers are against introducing new micro-architecture specific optimizations as it affects new ARM processors.

The Linux 6.7 merge window has been downright exciting with additions like Nouveau GSP support and the Bcachefs file-system being added. It's also been downright massive as one of the largest merge windows in recent history in terms of code changes. Here's some statistics of the Linux 6.7 merge window ahead of today's Linux 6.7-rc1 release.

One of the great niche features of Ubuntu Linux has been the Ubuntu Mainline Kernel PPA that's been maintained by Canonical for providing daily kernel builds of the Linux Git kernel state as well as of all point releases and release candidates. Sadly it's now been broken for one month for this very convenient feature.

The LLVM project is now employing profile-guided optimizations (PGO) when building their x86_64 Microsoft Windows release packages. Making use of PGO is able to make their Clang build a stunning 22% faster.

Ahead of the official release announcement due out tomorrow, the Mozilla Firefox 120.0 release binaries are now available.

In addition to the OpenZFS code this week landing sync parallelism to improve write performance scalability, another shiny new feature was also merged: RAIDZ expansion.

Another merge window, another attempt for Bcachefs to be mainlined. This file-system was submitted again today for the now-open Linux 6.7 merge window and it stands better chances this cycle of being upstreamed.

One of the many early pull requests sent in for Linux 6.7 were the x86/boot changes that are headlined by a rework to the PE header generation in order to generate a modern, 4K-aligned kernel image view to ultimately aim for better system security.

As mentioned last week, merged for the Linux 6.7 kernel is NVIDIA GSP firmware support in the Nouveau driver so that these NVIDIA firmware blobs can handle hardware initialization and power management related tasks. This support is optional right now for the GeForce RTX 20 / RTX 30 series hardware with Nouveau but necessary if wanting better performance via re-clocking the GPUs. The GSP firmware is a mandatory requirement for Nouveau with the NVIDIA RTX 40 GPUs and moving forward.

Earlier this month NVIDIA published the R545 Linux driver beta while today it's been promoted to the stable series with the NVIDIA 545.29.02 Linux driver release.

Back during the Linux 6.3 kernel support for a number of legacy DRM drivers was removed and now patches have been volleyed for taking things one step further by now eliminating the infrastructure for supporting these older user-space mode-setting graphics/display drivers.

Wine 8.20 is out today and it takes care of quite a vintage bug report... A feature request from 2010 to be able to register URL protocol handlers under Linux.

Slint as a reminder is a Rust-written open-source graphical toolkit that on Linux uses Qt currently underneath. Slint has been making good progress on its goals and today marks the availability of Slint 1.3.

The Canonical-developed Netplan has served for Linux network configuration on Ubuntu Server and Cloud versions for years. With the recent Ubuntu 23.10 release, Netplan is now being used by default on the desktop. Canonical is committing to fully leveraging Netplan for network configuration with the upcoming Ubuntu 24.04 LTS release and in turn also marking the Netplan 1.0 release.

Systemd 255-rc1 is out this morning and it's packed with even more features for this dominant Linux init system and a growing list of other system utilities. Systemd 255 even is introducing systemd-bsod as a "Blue Screen of Death" for displaying important error messages during boot failure, systemd-vmspawn as a new tool to spawn virtual machines, and other new features.

Google engineers on Wednesday posted an initial "request for comments" set of patches that re-implement Android's Binder code within the Linux kernel in the Rust programming language rather than C.
