In this update the main concern is with it's size, with the support of AMD's new Radeon RX Vega graphics card.
"4.12 is one of the bigger releases historically, and I think only 4.9 ends up having had more commits. And 4.9 was big at least partly because Greg announced it was an LTS kernel. But 4.12 is just plain big," said Torvalds.Linux 4.12 brought over one million lines of new code to the kernel since 4.11 through work on Direct Rendering Manager (DRM) for Vega GPUs, new disk and file-systems, updates for POWER9, ARM, and Nvidia processors, a USB Type-C port manager, and some kernel hardening in the form of Kernel Address Space Layout Randomization or KASLR, which is on by default for x86 systems - said Phoronix.
"Go test" to "Go out and use it". - say's Torvalds"In the diff department, 4.12 is also very big, although the reason there isn't just that there's a lot of development, we have the added bulk of a lot of new header files for the AMD Vega support," he explained.
