Both Kubuntu and Kubuntu Netbook Remix are now updated to 10.04.1. These new ISO images are updated to include all the post-release fixes delivered since Kubuntu and Kubuntu Netbook Remix were released. This release includes updated desktop installation CDs for the i386 and amd64 architectures and an updated ISO image for USB installs for netbooks.
If you are already running 10.04, there is no need to do anything except install all available updates. If you are doing a new installation, the updated 10.04.1 images will enable you to install a fully up to date system. Get them from our download page
