The Incremental GNOME 3.8: Doing What the Project Does Best
If you dislike the GNOME 3 release series, the new 3.8 version of the popular desktop environment won't change your mind. However, if you do use GNOME 3, you'll appreciate the enhancements. Essentially, 3.8 is an incremental release, in which the project does what it has always done best — making dozens of tweaks that affect the user experience (generally for the better) without making any major changes to how it works.
Like most software releases, GNOME 3.8 is full of changes that aren't likely to be visible to most users. In GNOME 3.8, these invisible changes include modifications of key libraries such as GLib, GTK+ and Clutter, as well as Python bindings and a new help interface in the GNOME 3 style.
However, the features that most users are likely to notice are the replacement of fallback mode with GNOME Classic, the changes to the main screen and the overview screen, and the addition of new top-level headings in the Settings dialog.
