The Linux 3.3 kernel
release might be imminent. In releasing the Linux 3.3-rc6 kernel, which Linus says is just made up of small fixes and clean-ups, he says this could be the last release candidate.
Here's the key part of his announcement
: "In fact, it's been calm enough that this *might* be the last -rc, but we'll see how the upcoming week goes. If it stays calm (and hopefully even calms down some more), there doesn't seem to be any major reason to drag out the release cycle any more. But hey, that does imply that people who have seen regressions should re-check them and holler loudly if they are still seeing problems."
