But, for now, let’s take a look at what we already know so far: #### 1\. 支持 WireGuard WireGuard will be added to Linux 5.6 – potentially replacing [OpenVPN][2] for a variety of reasons. You can learn more about [WireGuard][3] on their official site to know the benefits. Of course, if you’ve used it, you might be aware of the reasons why it’s potentially better than OpenVPN. Also, [Ubuntu 20.04 LTS will be adding support for WireGuard][4]. #### 2\. 支持 USB4 Linux 5.6 will also include the support of **USB4**. In case you didn’t know about USB 4.0 (USB4), you can read the [announcement post][5]. As per the announcement – “_USB4 doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols._“ Also, while we know that USB4 is based on the Thunderbolt protocol specification, it will be backward compatible with USB 2.0, USB 3.0, and Thunderbolt 3 – which is great news. #### 3\. 使用 LZO/LZ4 压缩 F2FS 数据 Linux 5.6 will also come with the support for F2FS data compression using LZO/LZ4 algorithms. In other words, it is just a new compression technique for the Linux file-system where you will be able to select particular file extensions. #### 4\. 解决 32 位系统的 2038 年问题 Unix and Linux store the time value in a 32-bit signed integer format which has the maximum value of 2147483647. Beyond this number, due to integer overflow, the values will be stored as a negative number. This means that for a 32-bit system, the time value cannot go beyond 2147483647 seconds after Jan. 1, 1970. In simpler terms, after 03:14:07 UTC on Jan. 19, 2038, due to integer overflow, the time will read as Dec. 13, 1901 instead of Jan. 19, 2038. Linux kernel 5.6 has a fix for this problem so that 32-bit systems can run beyond the year 2038. #### 5\. 改进硬件支持 Obviously, with the next release, the hardware support will improve as well. The plan to support newer wireless peripherals will be a priority too. The new kernel will also add the support for MX Master 3 mouse and other wireless Logitech products. In addition to Logitech products, you can expect a lot of different hardware support as well (including the support for AMD GPUs, NVIDIA GPUs, and Intel Tiger Lake chipset support). #### 6\. 其他更新 Also, in addition to all these major additions/support in Linux 5.6, there are several other changes that would be coming with the next kernel release: * Improvements in AMD Zen temperature/power reporting * A fix for AMD CPUs overheating in ASUS TUF laptops * Open-source NVIDIA RTX 2000 “Turing” graphics support * FSCRYPT inline encryption. [Phoronix][6] 跟踪了 Linux 5.6 带来的许多技术性更改。因此，如果你好奇 Linux 5.6 所涉及的全部更改，则可以亲自了解一下。 现在你已经了解了 Linux 5.6 发布版带来的新功能，对此有什么看法呢？在下方评论中留下你的看法。 -------------------------------------------------------------------------------- via: https://itsfoss.com/linux-kernel-5-6/ 作者：[Ankush Das][a] 选题：[lujun9972][b] 译者：[LazyWolfLin](https://github.com/LazyWolfLin) 校对：[校对者ID](https://github.com/校对者ID) 本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 [a]: https://itsfoss.com/author/ankush/ [b]: https://github.com/lujun9972 [1]: https://i0.wp.com/itsfoss.com/wp-content/uploads/2020/02/linux-kernel-5.6.jpg?ssl=1 [2]: https://openvpn.net/ [3]: https://www.wireguard.com/ [4]: https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-20.04-Adds-WireGuard [5]: https://www.usb.org/sites/default/files/2019-09/USB-IF_USB4%20spec%20announcement_FINAL.pdf [6]: https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.6-Spectacular
