It just happens to be one of those days where everything I use has to be updated. It started with Nessus, when opening my client I was prompted to download and install the new client. Nessus has moved from 5.2.4 to 5.2.5.
Later, it was on to auditing a small application, and that meant firing up Burp Suite. Burp notified that it needed to be updated from 1.5.20 to 1.5.21.
So, if you are using those apps, now is the time to update.
