Just in case you missed it on the forum.
Marc has posted the following:

Sorry guys but we are not continuing the birthday search.
I will update the collisions page with the latest collisions soon.
The good news is that we are going into stage 2: the eliminating of the remaining 8 bitdifferences.
And we are very far with the design to eliminate the first bitdifference.
It might be awhile before we present new work here at HashClash.
I am also very busy with finishing my studies.
But there are plenty of other BOINC projects for which you can crunch!
So no need to abandon HashClash and we'll keep you updated on our news section.
I will post more information soon.
