I haven't seen this announced anywhere, so here it goes:

http://www.cosic.esat.kuleuven.be/WeWorc/allAbstracts.pdf

Collisions for simplified variants of SHA-256
Krystian Matusiewicz and Josef Pieprzyk
pp. 140

Preliminary Analysis of the SHA-256 Message Expansion
Norbert Pramstaller and Christian Rechberger and Vincent Rijmen
pp. 145

Still work in progress, these two papers are just appetizers ;-)
