LiveCDs Are Outdated

#1 The List of LiveCDs located at https://wiki.trinitydesktop.org/LiveCDs are mostly outdated, meaning that they don't contain the latest version of TDE, although the page states "Unless otherwise marked, all of them contain the most recent version of Trinity". If LiveCDs are always gonna be late behind then the previous statement should be removed. #2 Whose working on Ubuntu Releases and Ubuntu Nightly? I'm pretty sure they are not official Ubuntu flavors so they must be community driven, and why are they so late behind with R14.04 version?
