Offensive Security has released Kali Linux 2019.1, the first 2019 version of its OS for cyber security experts. The latest version includes kernel up to version 4.19.13 and patches for bugs, along with many software updates. You can download the latest version straight away from here. Or if you are already using older version of the OS, you could simply run this command:

“Veyron has been moved to a 4.19 kernel, and the Raspberry Pi images have been simplified, so it is easier to figure out which one to use,” Kali Linux project maintainers says in their official release announcement.
