The M2 release is the first one with a release cycle as short as
three months. As such it was an experiment, and I think it was quite
a success. The milestone is released even though not all assigned bugs
could be closed in time. I think for now it's more important to send
out the signal that we are actually able to stick to such a release
cycle. May be we should be more realistic about what bugs/tasks to
assign for M3...
