Most of the tickets marked for 0.9.1 or 0.10.0 in Trac are about the signal
and stats modules. Warren and Josef, could you please have a look at those?
If they're not straightforward and important to fix they can be set to
Unscheduled.

There are several pull requests that are (almost) ready to go in; of the
ones that still require some work or review I think especially #21 (discrete
state-space, transfer function and LTI systems) and #55 (QR decomposition
with Q multiplication) would be nice to have merged.

Here is a proposed schedule:
Sun 11 Sep: beta 1
Sun 25 Sep: rc 1
Sun 02 Oct: rc 2 (if needed)
Sun 09 Oct: final release

Does that work for everyone?

Cheers,
Ralf
