14 DAY TRIAL // After informing us about the release of Linux kernel 3.12.59 LTS, kernel developer Sasha Levin is back today, April 28, 2016, with details about the twenty-third maintenance build of the long-term supported Linux 4.1 kernel series.
According to the appended shortlog, Linux kernel 4.1.23 LTS appears to be a fairly normal update to the Linux 4.1 LTS (Long Term Support) branch, which is currently used in several GNU/Linux operating systems, and it changes a total of 64 files, with 949 insertions and 400 deletions.
"I'm announcing the release of the 4.1.23 kernel. All users of the 4.1 kernel series must upgrade," says Sasha Levin in today's announcement. "The updated 4.1.y git tree can be browsed at the normal kernel.org git web browser: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary."
Here's what's new in Linux kernel 4.1.23 LTS
There's a little bit of everything in Linux kernel 4.1.23 LTS, starting with improvements to the PA-RISC, ARM, and x86 hardware architectures, as well as to the EXT4 and Btrfs filesystems, small fixes to the sound and networking stacks (mac80211 and IPv4), and various core kernel enhancements.
The list of changes continues with updated drivers, and looking at the diff from the previous maintenance release, version 4.1.22, today's update brings DMA, general-purpose input/output (GPIO), GPU (mostly Intel i915), AU02828, SCSI, thermal, eXtensible Host Controller Interface (xHCI), Xen, and many USB changes.
As usual, if you are using a GNU/Linux operating system powered by a kernel from the long-term supported Linux 4.1 series, it is recommended that you update to version 4.1.23 as soon as possible, or as soon as the new package lands in the main software repositories of your distribution.
Alternatively, you can download the Linux kernel 4.1.23 LTS sources right now via Softpedia or from the kernel.org website and compile them yourself (only recommended for advanced users and OS vendors). More details should be found in the archive.
