Yes. Guess I should reread such a paragraph a few times before committing.

The only reason I've not made a 1.5 branch yet is I will only have time for
a numpy release cycle at or towards the end of this scipy release cycle.
Saves some backporting. If you think it'd be useful to do it now please let
me know.

Done. For the previous releases I put only the final release there. Maybe
good to announce beta/rc releases but then just update the announcement
instead of adding new items each time. It's a small sidebar after all.

The scipy.org announcement is in there. I'll add a "check the release notes
for ..." item.

Here is my checklist of things to do before 0.8.0rc1. I'm traveling (without
computer) for the next week, so if anyone wants to tackle any of these
items, that would be be very helpful.
- remove stuff in scipy.io as explained in 0.7.0 release notes
- fix paver dmg task to include docs
- add sphinxext to tarballs?
- check numscons works
- SSE instruction ticket: http://projects.scipy.org/scipy/ticket/1170
- linalg.qr: http://projects.scipy.org/scipy/ticket/243
- windows crash: http://projects.scipy.org/scipy/ticket/1102
- invalid 2.6 syntax: http://projects.scipy.org/scipy/ticket/1193
