These software distributions, potentially containing defects, are versions of applications or systems made available to users before full validation. Such versions can range from internal builds used for initial testing to public releases intended for wider user feedback, often characterized by the presence of unresolved issues that may impact performance or functionality. A common example includes a beta version of an operating system distributed to a select group of users for testing purposes.
The circulation of these versions plays a crucial role in the software development lifecycle. It allows developers to gather real-world usage data, identify and rectify unforeseen errors, and refine the product based on user input. Historically, the practice has evolved alongside software complexity, transitioning from limited internal testing to more open models that leverage the collective experience of a broader user base to improve software quality.
