      Hey jeffrey.allen,

      Here are the slides from my .live talk.  Consider adding the example from slides 3&4 which highlights previous version behavior over the new behavior when issuing a snapshot read.  Prior to 5.0 snapshots read could be done in a transaction, but transactions only run on primaries. So the workload isolation part that Jane was referring to is now with this project complete, snapshot reads can be done outside of transactions and thus run on secondaries.  

      Also from our notes, a reminder to call out that if a query does run longer than our current 5 min history window, the snapshotTooOld error can be returned.
