Hi Eric - Each of the Semi-annual Channel releases will be supported in
market for 18 months. So at any point in time, there will be 3 releases
in market (since we will put out new ones every 6 months). You also have
the flexibility regarding when you will deploy the new releases (i.e.
it's not an automatic deployment/update) and you can actually skip one
release (but not two), so you can go as long as one year between
deploying new releases.
