ImplementationVersion

ImplementationVersion refers to a specific release or build of a software system or component. It is a concrete instance of a versioned artifact, distinguishing it from the abstract version number or release name. For example, while a software might have a version "1.2.0", an ImplementationVersion could be "1.2.0-build.456" or "1.2.0-rc3", indicating a particular compilation or pre-release state.

Tracking ImplementationVersions is crucial for several reasons. It aids in debugging by pinpointing the exact code that was running when an issue occurred. It facilitates reproducible builds, ensuring that a specific set of code and configurations can be rebuilt identically. In environments with continuous integration and continuous deployment (CI/CD), each successful build typically generates a unique ImplementationVersion, allowing for precise tracking of deployed software. This also supports rollback procedures, enabling a return to a previously known stable ImplementationVersion if a new deployment introduces problems. Furthermore, it is essential for auditing and compliance, providing a clear history of what software was deployed and when. Various systems and tools employ different schemes for generating and managing ImplementationVersions, often incorporating build numbers, commit hashes, or timestamps.
