It’s not uncommon in the open source world when things are delayed – it’s rarer that they have an actual release date to begin with. Fedora 18 has been no stranger to these delays, as it originally was supposed to be out in November last year. So it’s unsurprising that the final release has been delayed yet again.
At the scheduled Go/No-Go meeting, the Fedora team decided that the presence of some unresolved blocker bugs should push back the release by another week. From now on, each week a meeting will be held to decide whether or not 18 is ready for release.
