The latest version 2021.1 comes with enhancements to existing features, new hacking tools, and an updated core packages.
New Features In Kali Linux 2021.1
Tweaked GTK3 theme on Xfce 4.16
One of the highlight features of Kali Linux 2021.1 is the addition of command-not-found package by default.
The Command-Not-Found not only suggests you install a package when it’s not already installed, but also points out the typo error with the correct word and gives the original message of “command not found” for an invalid command that doesn’t exist in Kali.
As you may know, in the previous version 2020.4, Kali Linux partnered with CrackMapExec (CME) tool author byt3bl33d3r.
