The revolution happened and now it is time for evolution. We dive into the following questions:

• How did leniency help the initial adoption, but why and how do we lean more on strictness today?
• How can upgrades be improved to avoid any downtime even when changing major versions?
• How can new resiliency features improve recovery scenarios and add totally new features?
• Why are types finally disappearing and how are we are trying to avoid the upgrade pain as much as possible?
• What are examples for some clever performance improvements?
• How can you shrink and (finally) split shards in a highly efficient way?

Attendees learn both about new and upcoming features as well as the motivation and engineering challenges behind them.
