This changeset looks good to me, but I think we need to either:

1. Stage all of the 3.2 changes in a new branch and then merge it all at once to develop.
2. Change the epoch definitions in this PR so that Epoch 3.2 won't activate without a followup PR that sets the block heights, latest epoch, etc.

I definitely prefer 2, seems way cleaner (i am preparying a very tiny pull request just for the activation)
