If you’re already to try (risk) your blog and be an early adopter, head over to the Wordpress 2.7 Beta staging ground and download your copy! I’ll skip and wait for the late November release.
A quick overview of the major changes of the 2.7 beta from freshmeat.net:
WordPress 2.7 has a newly redesigned administrative interface, the result of much user feedback and testing. New features include a built-in WP core upgrade function, plugin directory browser/installer, the ability for child themes to override individual template files, sticky posts, improved comment management, and much more.
