please don't flood the lists with 6 versions in a single day.
Generally we want 1-2 days betwqeen versions to give people time
to actually review them.

All changelogs contain at least some changes that should have been
caught before sending patches to the lists. So please don't iterate
by sending patches and instead test locally and make sure _everything_
works before sending patches.


Thanks
Heiko
