After a long wait since 5.1.1, KNOPPIX 5.3.1 is out as an official public release.
I’m very, very pleased with 5.3. My only quibble is that there is only a DVD version, not a CD version. I do work on computers without DVD drives, as uncommon as they are becoming. Granted, 5.1 usually works on such systems, but I would still like to be able to keep both a CD and a DVD around of 5.3.
On systems with DVD drives, best version yet!
