The GNOME 3.2.1 release announcements (with links to the complete change-logs) can be found on the GNOME announcement mailing list. A GNOME 3.2.2 point release is planned for the middle of November.
Meanwhile, all major development efforts are centered around GNOME 3.4. The first development release in the road to GNOME 3.4 is due out next week. The release of GNOME 3.3.1 next week Wednesday is to be the first development release for testing and it also marks the end of feature proposals for GNOME 3.4, after that it's time to debate the proposals while the GNOME release team has the last say in the matter.
GNOME 3.4 will be in beta around the 22nd of February, release candidates in March, and the official GNOME 3.4.0 release is scheduled for the 28th of March, 2012. Among the expected work for GNOME 3.4 is finishing up the application menu, gnome-boxes as a GNOME application for accessing other computer systems/images using libvirt, enhancements to GNOME Documents, network zones support in GNOME, and other desktop features. Some of the slated GNOME 3.3/3.4 features are mentioned on this GNOME Live page.
