At the time of this writing it still does not appear in The Linux Kernel Archives, or not on your home page, but the launch has occurred. In fact, it was yesterday that Linus Torvalds made it public by reporting in his weekly rotating, where he explains that the last few weeks have been very quiet. If not, Linux 5.1 it could have needed one more Release Candidate and the release would have occurred on May 12.
If you are a user who likes to use long-term supported versions, Linux 5.1 is not for you, since it is not an LTS version. The latest LTS version is Linux 4.19.40. This version is recommended to users who want to enjoy the latest news sooner or to all those who are experiencing hardware problems that the new version could solve.
Linux 5.1 arrives with these news
- Ability to use persistent memory as RAM in addition to physical RAM.
- Ability to boot into a device-mapper device without using initramfs.
- Cumulative patch support for the new Live Patching feature.
- Zstd compression levels can now be configured.
- The fanotify-based monitoring system has been improved by adding what they call “super block root watch” to the fanotify interface.
