I was trying to get the torrents for 14.04.4 (both versions), and on your page at http://www.kubuntu.org/getkubuntu/, the links are old and pointing to 14.04.3. I copied the link and by removing the last part of the path (http://cdimage.ubuntu.com/kubuntu/releases/trusty/release/), I found that 14.04.4 is available, but the links are just old. I then clicked on "Contact us" at the bottom, which took me to http://www.kubuntu.org/contact-us/. After reading that page, I tried to click on the link at the top for the support page, which took me to http://kubwp.kubuntu.co.uk/support/, which gave a 404 error. I then went back, and noticed the link for reporting a problem with a website at the bottom, which brought me here. Just thought you'd like to know those links need to be updated!
Thank you for reporting. I've fixed these issues.
