During a Sprint Review, the Product Owner determines that she is going to release thecurrentIncrement...

The Sprint Review is an event that inspects the outcome of the Sprint and determines future adaptations. The Product Owner has the authority to release the Increment to production at any time, but this does not mean that the Sprint has to be stopped or changed. The stakeholders can provide feedback and suggestions for the product, but they cannot interfere with the Sprint Goal or the Sprint Backlog within the Sprint. The Scrum Team can decide to:

Continue sprinting but shorten the Sprint length to allow for shorter feedback loops (A), which is a valid option if the Scrum Team agrees that this will improve their agility and value delivery. However, this should not be done frequently or arbitrarily, as it may disrupt the rhythm and focus of the team.

Continue sprinting and include the customer feedback in the Product Backlog ©, which is the most appropriate option as it respects the empirical nature of Scrum and allows the Product Owner to prioritize and order the Product Backlog based on new insights and stakeholder needs.
