Software release life cycle is a process that all software goes through before it can be used. It starts with developers writing code to create the software and then testing the software to check that it works properly. After that, people do more testing to make sure it can handle different conditions and unexpected errors. Finally, the software is released to the public and more people use it. As they use it, they can give feedback to the developers who can then update and improve the software to make it better. This cycle goes on until the software is no longer in use or supported by the developers.
