OpenSSL 4.0 was just released as a big update for this widely-used SSL/TLS and crypto library.

Merged yesterday for the Linux 7.1 kernel is overhauling the T10 PI code for generating and verifying data integrity information. In turn the new code is cleaner while also allowing for better read storage performance.

As a big helper for Valve's Steam Play with DXVK and VKD3D-Proton, the Mesa Radeon Vulkan driver "RADV" has merged its initial support for the VK_EXT_descriptor_heap Vulkan extension.

A request made a KDE user all the way back in June 2005 on KDE 3.3.2 is finally resolved. After being sought after for 21 years, the latest KWin code now has support for per-screen virtual desktops.

All of the power management subsystem feature updates have been merged for the Linux 7.1 kernel.

Over the course of March there was much progress made on the ARM64 port of Haiku OS, the open-source operating system serving as the spiritual successor to BeOS.

Merged yesterday were all the CRC code updates for the Linux 7.1 kernel. Most notable with that pull is an ARM64-optimized CRC64-NVMe implementation that can deliver multiple times faster performance.

Jemalloc 5.3.1 was released today with next month marking four years since the prior release, jemalloc 5.3.0. While the version bump may not seem like much, jemalloc 5.3.1 comes with many performance improvements, new features, and other enhancements.

Last month we showcased GreenBoost as an open-source means of augmenting NVIDIA GPU vRAM with system RAM and NVMe storage. This memory tiering solution for NVIDIA GPUs was developed by an open-source developer with a focus on CUDA and allowing larger LLMs to be handled on graphics cards with smaller vRAM capacities. There was a setback to the project due to NVIDIA legal but now the project is going in new form and also has introduced GreenBoost-Proton for helping Linux gaming on NVIDIA hardware.

For those that had purchased a StarBook MK VI laptop 3+ years ago over the advertised support for Coreboot, Star Labs has now delivered with a Coreboot build finally available and working for this AMD Ryzen 5000 series powered laptop.

On this first day of the Linux 7.1 merge window, among the early pull requests merged were beginning to land the various VFS pull requests submitted by Christian Brauner. Among that code merged is enabling support for user.* extended attributes on sockets.

The Spack package manager is quite popular in the HPC / supercomputer space for scientific software. Even with the more selective niche than a typical general purpose OS package manager, large language models (LLMs) have already proven capable of being useful in generating new Spack packages. But there have also been some headaches involved too for Spack developers.

Last year NVIDIA announced the new CUDA Tile programming model as one of the biggest updates ever to the CUDA platform. CUDA Tile brings a virtual ISA for tile-based parallel programming and they subsequently open-sourced the CUDA Tile IR as an intermediate representation built atop LLVM's MLIR. Now they are looking to hire additional LLVM compiler engineers to help foster their CUDA Tile initiatives.

In advance of the Linux 7.1 merge window opening, Miguel Ojeda sent out all of the Rust feature updates on Friday. This includes bumping the minimum Rust version for building the Linux kernel as well as a new experimental option that can provide better performance for Rust code within the kernel, alongside other updates.

Mold 2.41 is out as the latest major update to this high performance linker and viable alternative to the linkers from the GNU and LLVM projects.

Sent out today was an initial patch series for comment on introducing the FTRFS file-system. The FTRFS proposal is more interesting than last week's VMUFAT file-system proposal.

The open-source, Rust-based Servo browser engine has been improving its Servoshell demo browser application while one of the most promising potentials for this engine is around embedded use as an alternative to the Chromium Embedded Framework (CEF). With the latest moves by Servo developers, they are making for a more compelling story for its use.

For those wishing to make use of modern OpenCL 3.0 capabilities on AMD APUs/SoCs with integrated Radeon graphics using Mesa's Rusticl driver, an improvement was merged this weekend to the RadeonSI driver ahead of this quarter's Mesa 26.1 release.

Nearly one year ago to the day I noted Linux developers were considering the removal of the Apple HFS and HFS+ file-system drivers from the kernel. They were orphaned the past decade and turning into a maintenance burden for upstream developers. But then to some surprise, a few developers stepped up to maintain the HFS(+) drivers. One year later it's proving to be a success story with more fixes for this aging Apple file-system support continuing.

Merged for the Linux 7.0 kernel was a power sequencing driver for PCIe M.2 connectors as part of an effort to allow describing PCIe M.2 connectors in Device Tree files. For Linux 7.1, that driver is extending support for PCIe M.2 Key E connectors.
