Fedora release cycle -- F18 January 2013?

[James Freer]

I was looking at the release cycle dates which are aimed for 1 May
(may Bank Holiday) and 31 Oct (Halloween).

F18 came out this month (instead of November 2012) - i installed F17
in December thinking i was installing the latest version (ok it was
but not what i thought). I assume there were problems to be overcome
or is it released quite often a couple of months late.

thanks
