It unfortunately does not work like that. Bugs are fixed as developers choose to fix them. And we guarantee some level of support (we do not let thing rot that is).
I see present 3.2.4 http://www.gramps-project.org/bugs/roadmap_page.php?version_id=21
has some resolved bugs already, so a release could be done. It is a holiday period however.
I have not been tracking the bugs in 3.2.3, is there a real issue which would require a new bug fix release? If not, I would rather aim for a bug fix release end of august if the release manager has time.
