I have the M210 and on the DJI website it doesn't show anything for the M210 anymore only for the M210 V2.  Are the updates for the M210 V2 the same updates for the M210?  Thanks for the help

DJI actively routes all traffic to the newer Matrice 200 series.
If you need some 'older' info, you have to go to https://www.dji.com/matrice-200-series

If you mean aircraft firmware updates, then no, these are different between V1 and V2
