Homonym: rollback (Reversion)
A "rollback" refers to the process of reverting a system, application, or database to a previous state. This is often used in computing to undo changes that may have caused issues, such as bugs or data corruption. By restoring to an earlier version, users can recover lost data or eliminate problems introduced by recent updates.
In the context of software development, a rollback can be crucial during the deployment of new features. If a new version of software, like an application or a website, fails to perform as expected, developers can quickly revert to the last stable version, ensuring that users experience minimal disruption.
