Knoppix 7.5, Linux Magazine Edition, released in conjunction with the CeBIT 2015 Exhibition, can be found on the April Edition (No. 173) of the UK version of Linux Magazine.

Before anyone starts jumping up and down demanding the public edition should be available for download it is as well to remember that past experience is that the .1 public edition does not usually appear till later, (maybe as late as September). The benefit of the wait is you get some bugs fixed. Klaus Knopper releases when he is ready.
