So how about we make that explicitly stated?

1 is hopfully right. 2 should be, but we haven't received many bug
reports for people with the alphas. Which certainly *could* mean that
1 made there not be many bugs, but it could also mean that people
aren't really testing it, just tasting it.

It is, unless it's because we created those open items by committing
things too late in the cycle, even though it wasn't quite ready, "so
the author won't have to wait another year for a release".
