GNOME 2.29.4 version is now available. GNOME 2.29.4 is still considered developmental quality but represents a milestone that is a step closer to the final release of GNOME 2.30, which will come in March of 2010.
There are many new cool staf in this release, like an updated nautilus with its changed focus , or various modules like gnome-control-center with tons of bug fixes. You can also take a look at gnome-keyring which has changed quite a bit internally… There are definitely many changes in there.
