libsoup 2.3.0 will be merged to svn head and released later today, to become a part of GNOME 2.22. This is an API-breaking release, so everything that uses libsoup needs to be ported to the new release.

I am about to attach patches for evolution-exchange. Unfortunately, while I've tested that they compile, I don't really have the infrastructure to really test that they *work*. At any rate, you can see that most of the changes are fairly mechanical renamings, so there shouldn't be major problems (and any minor problems should be worked out before 2.21.90).
