Back in 2021 Facebook open-sourced CacheLib as a new caching engine . Back in 2021 it was done to help scale services with non-volatile memory caching to offset increasing DRAM costs at the time. Now in 2026, DRAM memory prices are astronomical compared to 2021 pricing given the AI surge. And, surprisingly, Meta is out with a new CacheLib release after being absent the past two years.

CacheLib was originally started to help with caching on non-

In addition to the release today of Sway 1.12 for that i3-inspired Wayland compositor, Labwc 0.20 is also out today as another wlroots-based Wayland compositor.

Labwc continues with its focus as a window-stacking Wayland compositor. This lightweight compositor inspired by Openbox continues to leverage the wlroots library to help in the heavy lifting. With labwc 0.20, it's re-based against wlroots 0.20.

Labwc 0.20 introduces a much requested "

Sway 1.12 is out today as the newest feature release of this i3-inspired Wayland compositor powered by the wlroots library.

Sway 1.12 introduces HDR10 support when running with its Vulkan renderer option. HDR10 is the most prevalent open standard formant for HDR video content.

Sway 1.12 also introduces support for capturing individual windows, a new "--device-primaries" option to use the color primaries advertised by the display's EDID data, support for keypad

Merged today for what will become Mesa 26.2 next quarter is the Radeon Vulkan driver "RADV" now supporting the VK_KHR_shader_fma extension.

VK_KHR_shader_fma was introduced to the Vulkan spec last year for applications wanting correctly-rounded fused-multiply add (FMA) operations. This is particularly useful for machine learning and scientific computing applications leveraging Vulkan for GPU acceleration and wanting to ensure floating-point accuracy.

The Vulkan extension spec text for VK_KHR_shader_

An exciting Intel innovation expected to be added for the upcoming Linux 7.2 kernel is introducing the new USB4STREAM protocol for USB4/Thunderbolt as a "super simple" way to "basically just transfer raw packets from one host to another". This can be useful for quickly backing up a system from one host to another, sharing of web cameras or other peripherals across systems, or other environments where not having networking or wanting to avoid the traditional Linux networking stack.

Intel Thunderbolt maintainer Mika Westerberg has been

With Linux 7.1 ISDN, ham radio, and other old network code was removed in lightening the kernel source tree by around 138 thousand lines of code. Some additional Linux networking code cleaning is expected for Linux 7.2 with the ISA and PCMCIA hardware around ARCnet set to be removed.

For those still using ARCnet for that pre-Ethernet networking technology from decades ago, Linux kernel developers plan to end support for ARCnet with ISA and PCMCIA adapters. Linux developers acknowledge ARCnet is still used in some embedded

Redis 8.8 reached GA today for the Redis open-source project providing a high performance, in-memory data store.

Notable with Redis 8.8 is introducing an Array data structure. Yes, finally having native array support within Redis for use-cases like aggregating or grep'ing data remotely or when having data dependent upon the relative position. Details on the new array type for Redis can be found via this pull that landed the array support.

Redis 8.8 also brings new performance improvements like now

While not as good as repealing AB 1043 outright for requiring operating system providers to ask for a user's age or birth date at device setup, open-source Linux distributions and other open-source OSes may end up seeing some reprieve before this law goes into effect at the start of 2027.

AB-1856 is currently undergoing committee reviews and could be voted on by the California State Legislature in June. AB-1856 makes some important adjustments to exempt

In the road to releasing Linux 7.1 in June, out today is Linux 7.1-rc5 that continues coming on heavy with fixes.

Linux 7.1-rc5 brings more code fixes crafted by different AI coding agents like GitHub Copilot and Claude Code. The AI-driven fixes scatter the kernel spectrum from different graphics driver bugs to security issues being addressed in the C code. During the networking fixes merge this week, the merge request noted the craziness continues with no end in sight . There
