You can check it here: http://wiki.sugarlabs.org/go/0.90/Notes#Dependencies
I will be updating that page as we require newer minor versions
because of any bugs fixed during integration testing.

We would need to backport a ton of bugfixes from mission-control 5.5.x
to 5.4.x along with refactorings, I'm afraid we'll do better by
sticking with the upcoming stable release.
Just to be clear, I see why you would have liked to stop building
telepathy (and any other sugar dependencies) in jhbuild but if the
Sugar community is going to be involved in the development of the
platform we use then we are going to invariably have to depend on
stable releases not yet released.
For the last years we have been in a situation in which we were able
to just use the platform as it was and workaround any issues inside
Sugar, but GNOME is now transitioning to a new API and this:
- forces us to adapt Sugar to the new API by dropping dependencies and
acquiring new ones (which may not have had a stable release yet),
- and also gives us an opportunity to influence it with our work so we
end up breaking some limitations and we can remove workarounds.
It's also relevant that our most important distro today is Fedora and
it is very willing to drop obsolete components and "encourage"
upstreams to move on.
As an illustration, Read won't work in F14 because the python bindings
were broken and we were told to use introspection instead, of which
there isn't an stable release yet. It should serve to us as a warning
of what will come in F15.
In summary: we need to do work on the platform if we want to remove
long-standing limitations and keep being shipped in distros, and this
will mean that we cannot solely rely on already packaged components.
