Event sourcing: projections and replay

When an event-sourced system changes a projection's logic, what is the standard way to correct existing read models?
Options
  1. 1Edit the stored events in place. Make their payloads match the new projection logic.
  2. 2Delete the entire event stream. Bootstrap a fresh read model from current state.
  3. 3Replay the event stream through the new projection into a fresh read model
  4. 4Run an UPDATE against the event table. Rewrite the fields the projection depends on.
