Ο Linus Torvalds released the new Linux kernel 5.4 series, a major release that adds many new features, greater security and updated drivers for new hardware.
Linux kernel 5.4 has been in development since early October and had a total of eight Release Candidates. It has many new features such as system support files Microsoft's exFAT, which was eventually built into the kernel.
Another major change that the Linux kernel 5.4 has is the core locking capability, something that offers extra security as it can restrict access to the kernel in some applications.
AMD fans will rejoice, as Linux kernel 5.4 supports AMD Radeon Navi 12 and 14, AMD Radeon Arcturus GPUs, as well as AMD Dali APUs. It also supports AMD Ryzen 3000 series CPUs and AMD EPYC microprocessors for improved load balancing.
He supports them processors Intel Tiger Lake, τα Qualcomm Snapdragon 855 SoCs, και τα Intel Lightning Mountain SoC. Προσφέρει βελτιωμένη διαχείριση μνήμης εφαρμογών στο Android, και διαθέτει ένα νέο virtio driver υψηλής απόδοσης για την κοινή χρήση αρχείων μεταξύ hosts και guests. Διαθέτει ένα νέο χαρακτηριστικό ασφάλειας για την ανίχνευση αλλοίωσης αρχείων που ονομάζεται fs-verity αλλά και το dm-clone για την live ζωντανή κλωνοποίηση των block devices.
Ο Source Code του Linux kernel 5.4 5.4 είναι availables to download from kernel.org if you want to do the compile yourself.
But keep in mind that at this time the new kernel is still in "mainline" state, which means that it is still considered a version that is not ready for mass adoption. The 5.4 version will become "stable" one or two weeks after its first release. so it would be a good idea to wait at least two weeks.
