Just saw this tweet from @chx1975:
If you are organizing a Drupal 7 release party why dont you assign a major bug to yourself and get it done during the party? #d7rp

Two things I like about it:

1. You see, it is very well possible to have a release party while you know there are still bugs.

2. nice idea to combine a bugsquash party and a release party: double fun.
