Welcome to our first release of 2018, Kali Linux 2018.1. This fine release contains all updated packages and bug fixes since our 2017.3 release last November. This release wasn’t without its challenges–from the Meltdown and Spectre excitement (patches will be in the 4.15 kernel) to a couple of other nasty bugs, we had our work cut out for us but we prevailed in time to deliver this latest and greatest version for your installation pleasure.

Churn, especially in security practices and software, is the best state imaginable for generating vulnerabilities.
New software means new bugs, unfamiliar setup requirements, newbie user mistakes, in addition to the 33% or more of users who accept phishing emails.
2018 looks like a great year for security churn.
How stable is your security? (Don’t answer over a clear channel.)
