A "beta version" is a preliminary release of software that is made available to a limited number of users for testing. This version is not the final product, but it allows developers to gather feedback and identify any bugs or issues before the official launch. Users who participate in beta testing can help improve the software by reporting problems and suggesting features. Beta versions are often used by companies like Google and Apple to refine their applications, such as mobile apps or operating systems. By involving real users in the testing process, developers can ensure a smoother experience when the software is finally released to the public.
