Linus Torvalds comes released version 5.0 of the Linux kernel, named "Shy Crocodile". Linux 5.0 includes Google's new encryption technology, as well as support for AMD FreeSync, Raspberry Pi, and other goodies.
Linux 5.0 arrived on March 3, 2019. As Linus has explained Last January, on the Linux kernel mailing list (LKML), it's not really a huge version:
The change of numbering does not indicate anything special. If you want to have an official reason, it's because I ran out of fingers and toes to count on, so 4.21 became 5.0 …. There is also no major special feature for version numbering. Of course, depending on your particular interests, some people may well find such a feature that they think it can make it a reason to increase the major number.
So unleash yourself. Invent your own reason why it's 5.0.
You have several reasons to choose. OMG Ubuntu has a good summary of the most interesting:
Linux file system encryption (fscrypt) now provides built-in support for Adiantum, Google's new fast encryption technology for low-end phones and light devices Internet of Things (IoT). You can use this technology on your Linux workstation with file systems such as EXT4 and F2FS (Flash-compatible file system).
For gamers, Linux 5.0 now has built-in support for AMD FreeSync, which provides adaptive refresh rates. In other words, it allows the computer to control the refresh rate of the display on the fly. This requires both AMD Radeon hardware and a display that supports FreeSync.
The Raspberry Pi Foundation offers an official 7 inch touch screen monitor. This latest Linux kernel provides built-in support for this hardware, making it easier for Raspberry Pi enthusiasts.
Linux 5.0 also supports other new devices, from NVIDIA Turing GPUs to keyboard shortcuts for Lenovo ThinkPad and Asus laptops.
If you use Linux, you probably will not have downloaded or manually compiled your own kernel. Instead, you will get Linux 5.0 when it is offered by your Linux distribution. For example, Linux 5.0 will probably appear in the next version of Ubuntu, Ubuntu 19.04 "Disco Dingo, Whose exit is scheduled for April 18, 2019.
