The X keyboard helper library used by GNOME (keyboard indicator, keyboard properties etc) is moved to new glib-based API (and gtk-doc based documentation). The new unstable release 2.91 is available on sf.net.

This release is ABSOLUTELY incompatible with GNOME 2.14. It will be
used in GNOME 2.15+. GNOME 2.14 and earlier should be built using the
v_2_x branch of libxklavier CVS.
