Software versioning is a process of assigning unique identifiers to different versions of a software product, which can be used to track and manage changes made to the software over time. It is a specialized skill that requires a deep understanding of software development and release management processes, as well as the tools and technologies used to support these processes. Versioning is an essential part of software development, as it allows developers to keep track of changes to their codebase, collaborate effectively with their peers, and maintain the quality and stability of their software products.
