	* configure.in: drop version back down to 2.2.5 and
	SOUP_API_VERSION back to 2.2; due to various snafus, there has
	never yet been an official release of the 2.4 API and the GNOME
	2.12 betas have been shipping with libsoup 2.2 tarballs (while
	jhbuild has been using 2.4, with evolution and related packages
	having configure hacks to build against either). As there never
	ended up being any API-incompatible changes in the 2.4 series, we
	can just merge it back into the 2.2 series and kill off 2.4.

	* NEWS: Copy in the 2.2-series news from the gnome-2-10 branch,
	and add new NEWS

	* libsoup-zip.in: s/2.2/@SOUP_API_VERSION@/

	* libsoup/Makefile.am (libsoupincludedir, lib_LTLIBRARIES,
	libsoup_2_2_la_LDFLAGS, libsoup_2_2_la_LIBADD,
	libsoup_2_2_la_SOURCES): s/4/2/ in all the places automake won't
	let us use a variable.
