Hi Vish, You are correct - as we stated in a previous answer, we have not yet released snp132 but are hoping to make it available soon and the current version of the track is based on snp131. You can find more information about the SNP track on the details page:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?&c=chr21&g=snp131 Hopefully this information was helpful and answers your question. If you have further questions or require clarification feel free to contact the mailing list at [email protected].
