It has already been said, but this is just a point release. If you keep your Debian system up to date (which you should) you'll only get a few new packages.<p>See also <a href="https://wiki.debian.org/DebianReleases/PointReleases" rel="nofollow">https://wiki.debian.org/DebianReleases/PointReleases</a>
I recently gave Debian a try and one thing that surprised me, coming from Arch, is that the tool to install software, apt-get, can't list what software has already been installed. You have to use dkpg to get that information.<p>Even funnier, I found the answer for that on the Arch Wiki page on Pacmac Rosetta:<p><a href="https://wiki.archlinux.org/index.php/Pacman_Rosetta" rel="nofollow">https://wiki.archlinux.org/index.php/Pacman_Rosetta</a>
Since I do apt-get update && apt-get upgrade almost regularly, I found out that my system was already running 7.3 (cat /etc/debian_version). So yes, this is not a major upgrade release just that the Debian team thought that there were enough changes and bug fixes to label this as a new release.
Can anyone point me to a step by step for how to get debian running on a macbook air? I've googled it and tried at least 4 different approaches, to no avail. I'm talking about a macbookair3,1 (late 2010 11").
