All customers will receive these updates with zero down time.  At the time the update is pushed, all agents that are logged in will receive a message box which says "A new version of the product is available. Click here or refresh your browser to use the new version." They can choose to accept the update or wait until they finish their current open work:

The first user that accepts the update for a specific interface will incur a cache hit, the cache for that interface will be re-created and that single user will experience a longer than usual refresh, but no other user of that interface will experience that lag.

Agent Browser User Interface is supported for the last five (5) Oracle B2C Service releases for all customers.  Therefore to maintain Browser User Interface support, you must upgrade Oracle B2C Service at least once a year. In order to leverage the latest and greatest of Agent Browser User Interface, we recommend you join the Auto Update Program and stay on the latest version of Oracle B2C Service.
