Because the devel branch is a rewrite that is not based
on master, so it needs to be merged on top of an empty
master.

	  - Completely rewritten launcher (Bugs 2336, 2365, 1323, 2262 and 1225)
	  - Various improvements in libxfce4panel (memory leaks, G_GNUC_INTERNAL,
	    GSList, canonical strings and fixed pedantic warnings).
	  - Libxfce4panel does no longer depend on libxfcegui4. This might cause
	    some problems with plugins. Plugin developers should add libxfcegui4
	    to the dependencies of their package (including cflags and libadd in
	    the makefiles).
