After the release of Linux kernel 3.2.76 LTS, the kernel developers have announced the immediate availability for download of the fourth maintenance release of Linux kernel 4.3.
According to the appended shortlog, Linux kernel 4.3.4 is quite a small release that changes a total of 64 files with 486 insertions and 186 deletions. As mentioned, it is a maintenance release that brings mostly bugfixes. Just by looking at the diff from Linux kernel 4.3.3, we can notice multiple drivers updates, especially for things like USB, ACPI (Advanced Configuration and Power Interface), Character Device Drivers, and networking (mostly Ethernet, but also PPP, USB, and PHY changes).
“I’m announcing the release of the 4.3.4 kernel. All users of the 4.3 kernel series must upgrade,” said Greg Kroah-Hartman. “The updated 4.3.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.3.y and 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.”
The networking stack has been updated
Besides the updated drivers, Linux kernel 4.3.4 is here to also improve the networking stack by fixing various issues with the IPv6 and IPv4 protocols, as well as with things like Bluetooth, AX.25, DECnet, IrDA, Open vSwitch, Stream Control Transmission Protocol (SCTP), and Transparent Inter-process Communication (TIPC). Additionally, there are also a couple of security fixes in the fourth maintenance release of Linux kernel 4.4.
As usual, we strongly recommend OS vendors to download the Linux kernel 4.3.4 build, compile it for their supported architectures, and release it to the default software repositories for users to upgrade as soon as possible. At the moment, there are numerous GNU/Linux distributions based on the Linux 4.3 kernel branch, including Ubuntu 15.10 (Wily Werewolf), Arch Linux, and Solus. You can also download Linux kernel 4.3.4 right now from Softpedia or via the kernel.org website.
