The latest Linux kernel boasts security, speed, and power improvements for Intel, AMD, ARM, and RISC-V architectures. . The latest Linux kernel is out with a slew of new features -- and, for once, this release has been nice and easy. As Linux creator Linus Torvalds wrote on the Linux Kernel Mailing List (LKML) : "It's been a calm release this time around … so here we are, right on schedule, with the 6.3 release out and ready for your enjoyment." While the straightforward release is good news, Torvalds warns there could still be challenges ahead: "That doesn't mean that something nasty couldn't have been lurking all these weeks, of course, but let's just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens." Calm doesn't mean boring. True, the features of this release are not as exciting as earlier ones that included Rust or Apple M1 support. But there are still some major new features in the Linux 6.3 kernel. Speaking of Rust , everyone's favorite memory-safe language, the new kernel comes with user-mode Linux support for Rust code. .

Linus Torvalds has announced the release and general availability of the Linux 5.19 kernel series as a major branch that brings more new features, improved hardware support, and lots of bug and security fixes. . After being in development for more than two months, Linux kernel 5.19 is finally here and introduces support for ZSTD-compressed firmware files, support for AMD’s Secure Nested Paging feature, a new user-space API for managing MultiPath TCP (MPTCP) flows, initial support for Loongson’s “LoongArch” RISC ISA CPU architecture, as well as support for the ARM Scalable Matrix Extension (SME). Also new support for supervisor-mode page-based memory types and the ability to run 32-bit binaries on 64-bit systems for RISC-V architectures, support for SMP coprocessors, KCSAN, and hibernation to the Xtensa architecture, a new generic ticket spinlock type to add support for full qspinlock implementation in various architectures like RISC-V, OpenRISC, and C-SKY, and a new FAN_MARK_EVICTABLE flag to the fanotify mechanism to avoid pinning the targeted inode in the inode cache.

The resurgence of Spectre-like malware has pushed the release date for the next iteration of Linux for at least a week, its creator has confirmed. . In the 5.17-rc8 announcement, the kernel development head Linus Torvalds explained that the discovery of CVE-2021-26341 - a vulnerability in some AMD processors that resembles the dreaded Spectre/Meltdown fiasco, meant the team needed to apply certain patches, which complicated things for the 5.17 version of the OS. “Last weekend, I thought I’d be releasing the final 5.17 today. That was then, this is now,” he writes. . Intel chip flaw pushes back Linux 5.17 launch, as engineers address safety concerns and ready critical updates..

No rest for the wicked! Days after the Linux kernel celebrated its 30th anniversary , Linus Torvalds, its creator and maintainer, put out its latest release with improvements to hardware support and security. “The celebrations will go on for a few more weeks yet, but you all may just need a breather from them. And when that happens, I have just the thing for you - a new kernel release to test and enjoy,” wrote Torvalds as he put out the new release. . The development cycle of the 5.14 release didn’t face any major hurdles and completed on schedule in just under two months. Reporting on the release, The Register notes that two of the headline features in the release are memfd_secret() system call and core scheduling, both of which are major efforts in the kernel’s attempts to mitigate the Spectre and Meltdown hardware vulnerabilities. .

Linus Torvalds has released Linux kernel version 5.11 with plenty of support updates for Intel, AMD and Arm-based hardware - and he seems to be content. "In fact, it's a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we're all set for the merge window to start," noted Torvalds announcing the release over the weekend. . Linux kernel creator Linus Torvalds has announced availability of the Linux kernel version 5.11, marking the first stable kernel release for 2021. The version arrived on Sunday's Valentine's Day with only a small amount of changes from the previous seventh release candidate (RC).

The latest Linux kernel release is certainly not a game-changer, but does offer some notable performance improvements that will make certain groups of users much happier. . Over the weekend, Linus Torvalds released the next Linux kernel: Linux 5.9. Torvalds said, "OK, so I'll be honest -- I had hoped for quite a bit fewer changes this last week, but at the same time there doesn't really seem to be anything particularly scary in here." So, if you're feeling brave, and you know how to compile your own Linux kernel , you can download all 115.5 MBs of the compressed Linux kernel 5.9 archive from kernel.org. Most of you, though, can afford to wait for it to appear in Linux distributions. That means, if you use a mainstream Linux distribution such as Fedora or Ubuntu , you can expect to run in their first 2021 releases. You don't have to be in a rush. The biggest change, support for the FSGSBASE instruction in Intel Ivy Bridge and later and AMD processors, will improve performance. But it only shows up if you're really pushing your RAM with many different loads. If you beat up your Linux server a lot, you'll see the change. I doubt a desktop user will spot it. . Linux 5.9 introduces major performance enhancements, including advanced kernel tracing with BPF Type Format and optimized scheduling for improved multi-core responsiveness.
