[Genome] Rat update and Cow dataset

[Donovan Chan]

Hello,
  I just had two quick question. First, I was wondering when a lastest version of the Rat genome would be uploaded.  The last version (rn4) was back in Nov 2004.  Second, concerning the cow genome sequence: Would it be possible to obtain the data set by Chromosome, instead of the full data set?  I know in the bosTau2, the information is available, but the most recent version would be best.  All the data sets have been of great help to my reserach.  Thank you for all your help
Cheers
