The Linux 7.3 kernel has been released on a Sunday afternoon, with the announcement noting no random delay. The final version arrived after a quiet last week of development. With this release complete, the merge window for Linux 7.4 opens tomorrow. The timing keeps the kernel's cadence on track.
This release is a record-breaker on all fronts, according to the announcement. It brought in 18,765 non-merge commits from 3,021 developers. Of those contributors, 807 were first-time kernel developers. That is an unusually large number of new participants.
Significant changes include binfmt_misc extensions and group-scheduling work aimed at improving performance on large systems. The release also introduces failfs, a new filesystem that fails all operations. The fchroot() system call is another notable addition. BPF programs now have global per-CPU data.
The sched_ext subscheduler feature is now complete. Virtual machines receive working-set tracking. The ntfs3 filesystem supports alternative data streams. SMB server improvements form a long list in this release.
These changes matter because Linux powers servers, desktops, mobile devices, and embedded systems. The record commit count signals strong community momentum. The features target performance, filesystem behavior, and virtualization. They also expand kernel programming capabilities.
The maintainer is on annual family vacation, so the 7.4 merge window will start later than usual. Instead of merging first thing in the morning, the maintainer will spend most of the day on a boat and under water. Merging will resume in the afternoon. The schedule is expected to remain unusual for a while.
Future outlook: The 7.4 merge window will collect new changes for the next kernel. Detailed summaries are available via LWN merge-window part 1 and part 2. The KernelNewbies 7.3 page also provides details. The kernel community continues to expand with each release.
