Software Update: OpenBSD 4.7

On Wednesday, the new semi-annual release of OpenBSD came out. on this page a comprehensive list of ftp and http download locations can be found. OpenBSD descends from the original Berkeley Software Distribution occasionally, and is known for its developers only wanting to use open source software. Furthermore, the OS is known for its excellent documentation and security. As usual with a new version of OpenBSD, there is also a new theme designed around the OS, accompanied by a real theme song and available on audio CD, as a poster and as a T-shirt. This time the title of the theme was ‘I’m still here‘. Below is a detailed overview of the changes implemented in version 4.7.
