Significant features in this release include the lazy preemption model for CPU scheduling, Arm64 Guarded Control Stack support, the PIDFD_GET_INFO() operation, multi-grain file timestamps, beginning atomic write support for the ext4 and XFS filesystems, the setxattrat(), getxattrat(), listxattrat(), and removexattrat() system calls, private stacks for BPF programs, a new mechanism for adding guard pages to a memory mapping, the removal of the reiserfs filesystem, and more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 6.13 page for more information.

Greg Kroah-Hartman has released the 6.1.126 stable kernel to fix build failures with the 6.1.125 stable release.

The idea of adding None-aware operators to Python has sprung up once again. These would make traversing structures with None values in them easier, by short-circuiting lookups when a None is encountered. Almost exactly a year ago, LWN covered the previous attempt to bring the operators to Python, but there have been periodic discussions stretching back to 2015 and possibly before. This time Noah Kim has taken up the cause. After some debate, he eventually settled on redrafting the existing PEP to have a more limited scope, which might finally see it move past the cycle of debate, resurrection, and abandonment that it has been stuck in for most of the last decade.

The 6.12.10, 6.6.72, and 6.1.125 stable kernels have been released on the expected schedule.
