14 DAY TRIAL // The Debian project has released the new Live CD images for the latest version of Debian 7.5 “Wheezy,” that was made available a week ago.
When a new point release of Debian is made available, the Live CD version of that distro is not accessible to users right away. It usually takes about a week for the Debian Live CD team to put together the new releases.
Even if the new Live images have been released, this is no reason to install Debian from scratch. If you already have Debian installed, the simple upgrade process will keep you up to date.
“Please note that this update does not constitute a new version of Debian 7 but only updates some of the packages included. There is no need to throw away old "wheezy" CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated,” reads the original announcement for the Debian 7.5 release.
All the Debian flavors have gotten their own Live Cd, including LXDE, GNOME, KDE, and the Rescue CD. The default implementation is Xfce.
You can find more details about Debian 7.5 “Wheezy” on the official website. You can download the latest Debian Live CD from Softpedia.
