user33852: Sites like http://xtnodes.com/ are tracking which versions of Bitcoin software are being used to create blocks. Where are they looking in the block structure to determine which software version generated the block?

user33852: Ah, not surprisingly, it's in the block's "version" field. It looks like core blocks are versioned as "v4", while "classic" blocks are versioned as "v805306368" and "BIP109".
