Yep. Primary changes for users are the ability to sieve larger q and lower memory usage. Neither f nor g compile out of the box. Both fail in linking due to undefined functions. I have spent no time trying to diagnose it. I've sent the patches to Serge to place in the SVN, but I don't think he's had time to do so. So I'll place them here.

The compile currently only works on Linux. Make sure cweb is installed on your computer. Then, download the original source and extract it. Then from the file attached, apply the patch lasieve5_ggnfs.patch and compile with
make gnfs-lasieve4I16e
and you should have a GGNFS compatible binary. If you wish to create a BOINC binary (which you generally wouldn't) then also apply the patch lasieve5_boinc.patch to add in the BOINC API.
