Latest raw Greengenes (unaligned) fasta files

Hello,

I would like to get the raw fasta files used by Greengenes, in order to construct some indexes with some other classifiers (centrifuge, kraken). It would also be preferable if these come with NCBI compatible accessions.
The most relevant link to a data repository I could find is this

http://greengenes.lbl.gov/Download/Sequence_Data/Fasta_data_files/

which points to a file last updated in May 2011.
Is there some place where I can get the latest fasta files from?

Regards,
Nikos

I think this is probably what you are looking for:

ftp://greengenes.microbio.me/greengenes_release/gg_13_8_otus/

edit: sorry, misread that you wanted the raw fasta, still this FTP server might have something.
