GNOME panel is, well, the panel in GNOME. You know, the bar you see at the top and at the bottom of your desktop, with menus and lots of applets on it. That's it. That's the panel.
This is the "J'aimerais avoir plusieurs écrans" release: Arvind has decided to fix some multihead bugs in the panel. The panel is supposed to work nicely in multihead setups, but it seems that there are not a lot of developers with such setups... Things should be better with this release, but help is always welcome
Since gnome-panel 2.9.2, the gnome-panel use the /apps/panel gconf directory to store its settings. The settings that were previously stored in /apps/panel/profiles will be automatically migrated. Since gnome-panel 2.9.2 also, the panel depends on gnome-menus and we should finally enjoy the freekdestop.org Desktop Menu Specification. If you don't see any items in the menus, then you probably forgot to set $XDG_CONFIG_DIRS to $(sysconfdir)/xdg
Thanks to everyone who contributed to this release.
