Linus Torvalds announced the release of the Linux 4.4 LTS kernel (Long-Term Support)
The Linux 4.4 LTS kernel (Long-Term Support) quietly and imperceptibly appeared, and Linus Torvalds informed about it. The novelty includes quite significant updates, including, for example, 3D support for virtual GPU drawers. Thanks to this, you can use hardware graphics support in guest VM. Also included is support for Open-Channel Solid State Drives (SSDs) via LightNVM.
Moreover, Linux kernel 4.4 LTS supports RAID5 MD, added the ability for non-privileged users to run eBPF programs. Polling support is also worth mentioning to improve the overall performance of high-end storage devices, mlock2 () syscal, and more. Improved support for 64-bit ARM, fixed issue with memory leak in Skylake CPU from Intel. Added the ability to work listening TCP sockets in non-blocking mode, the ability to determine the loss of TCP packets using RACK, added KMS driver for Malinka (Raspberry Pi), and xconfig translated into Qt5.
In the new version about 13 thousand corrections made by 1548 developers are accepted. Approximately 44% of all changes in the new version of the kernel are related to device drivers.
Old drivers have been updated, many new ones have been added, bugs and problems of previous kernel versions have been fixed. More information can be found here and here (in Russian).
')
Overall, Linux 4.4 LTS is the most advanced long-term branch among all others. It is likely that this version of the kernel will be used in Ubuntu 16.04 LTS (Xenial Xerus) and many other distributions. You can also hope for the integration of 4.4 LTS in Arch Linux.
