👉 Rollout in software development refers to a process of introducing new features or functionality to an existing application or system. The goal is to make the application more user-friendly and efficient, while also ensuring that any changes do not introduce bugs or other issues that could disrupt the normal operation of the system. In essence, rollouts involve testing and refining the software before it's released to the public. This process helps ensure that new features are delivered in a timely manner, without causing any significant disruptions to existing functionality
