I've noticed a couple of these: For example,
EOL Notice: Precise Pangolin (12.04) will be End of Life starting April 28, 2017
Non-EOL Notice: Quantal (12.10) remains supported through April 2014
Since statements of fact are unlikely to result in much discussion and the EOL dates are published upon release at https://wiki.ubuntu.com/Releases are notifications like this necessary?
