Kali Linux 1.0.7 was released.
"Kali linux 1.0.7 has just been released, complete with a whole bunch of tool updates, a new kernel, and some cool new features. Check out our changelog for a full list of these items. One of the new sought-out features introduced (which is also partially responsible for the kernel update) is the ability to create Kali Linux live USB with LUKS encrypted persistence. This feature ushers in a new era of secure Kali Linux USB portability, allowing us to either boot to a 'clean' Kali image or alternatively, overlay it with the contents of a persistent encrypted partition, all within the same USB drive."
Kali Linux (formerly known as BackTrack) is a Debian-based distribution with a collection of security and forensics tools. It features timely security updates, support for the ARM architecture, a choice of four popular desktop environments, and seamless upgrades to newer versions.
