In experimental you can find:
blender 2.48a: Finally (sorry for that) packaged. Upstream release logs: 2.47, 2.48.
python-networkx 0.99 and its companion python-pygraphviz 0.99: Quite a huge step forward, to polish things before a 1.0 release.
hugin 0.7.0: Lots! of things changed since the last upstream release. Grab it!
libgphoto2 2.4.3: Upstream release logs from 2.4.1 and even older.
Some of those packages have been there for quite some time already,
but experimental being what it is, a bit of advertisement is always
welcome I guess.
