The release of the free boot firmware Libreboot 20240612 is now available. This project builds on the Coreboot project, providing a replacement for proprietary UEFI and BIOS firmware responsible for initializing the CPU, memory, peripherals, and other hardware components, while minimizing binary blobs.
Libreboot aims to create a system environment that can operate without proprietary software as much as possible, not only at the operating system level but also in the firmware that handles booting. Libreboot complements Coreboot with tools that simplify the process for end-users, forming a ready-to-use distribution that any user without special skills can utilize.
Like the previous release, this update is labeled as a stable release and mainly differs by correcting errors identified over the month and implementing changes prepared during the build system audit. A new experimental branch is planned to be formed in July, which will serve as the basis for the next stable release expected in the spring of next year.
The size of the build script, written in POSIX sh, has been reduced by 12%. A driver for supporting booting from NVMe drives has been added to GRUB. On systems with Intel Haswell CPUs (ThinkPad T440p, W541, Dell OptiPlex 9020 MT, and Dell OptiPlex 9020), the use of the blob for memory initialization (MRC) has been discontinued, and a free implementation of raminit has been utilized instead.

In addition to Libreboot, a release of the Canoeboot 20240612 project has been formed, which positions itself as a completely free build of Libreboot that complies with the FSF's requirements for fully free distributions. The Canoeboot release is based on Libreboot version 20240612, from which components and changes that do not meet the FSF's criteria have been removed.
The need to create a separate build of Libreboot arises from the Free Software Foundation's established requirements for free distributions, which do not allow the delivery of binary firmware or any binary driver components. Starting from 2022, the Libreboot project has adopted more pragmatic rules for the usage of binary components, significantly expanding the range of supported hardware. The new goal of the Libreboot project is to support all hardware supported in coreboot, excluding binary components that impact security and reliability (for instance, Libreboot uses me_cleaner to disable Intel ME). With this approach, Libreboot lost its status as a fully free distribution from the perspective of the Free Software Foundation.
