Release Candidate (RC)
A Release Candidate (RC) is a version of software that has the potential to be the final product, pending testing and validation. It is developed after several iterations of testing and debugging have occurred, and it is deemed stable enough for further evaluation.
The purpose of a Release Candidate is to identify any last-minute bugs or issues before the software is officially released to the public. Typically, a Release Candidate will undergo rigorous testing by both developers and users to ensure that it meets all necessary requirements and functions as intended. If any critical issues are discovered during this phase, they must be addressed before the software can be officially launched.
Release Candidates are usually part of a larger software development lifecycle, which may include alpha and beta stages. While alpha versions are often incomplete and may contain significant bugs, and beta versions are more stable but not fully polished, a Release Candidate is expected to be feature-complete and free of major defects.
Once a Release Candidate passes all tests and receives approval from the stakeholders involved, it can be promoted to the final release. If significant issues are found, the development team may decide to iterate on the Release Candidate, fixing the problems and creating a new RC version for further testing.
In summary, a Release Candidate is a critical step in software development, representing a near-final version that is tested to ensure readiness for release.
