It is now possible to deploy all prepared modules at once after the Platform Server finishes upgrading. The Deploy All is another improvement from the Flexible Upgrades initiative that aims to reduce publish time and improve resilience during a platform upgrade, with the ability to resume development even before the preparation step finishes. To have your factory fully updated after each upgrade, you no longer need to do a solution publish or deploy one by one until the factory is fully published; use the new Deploy All functionality. The platform takes care of all required publishes, and you'll save a lot of time.
