What does release candidate mean in software engineering?

A release candidate (RC) is a version of software that has completed internal development and testing and is ready for final testing before an official release. It is stable enough for external users to test but may still contain minor bugs. The goal is to catch any remaining issues before the software goes live to all customers.

How do you use release candidate in a sentence at work?

You can say: We are shipping RC1 to staging for QA testing. or The release candidate passed all automated tests. or We found three bugs in the release candidate, so we need to create RC2.

Is release candidate formal or informal?

Release candidate is neutral in formality. It is the standard industry term used in both casual team discussions and formal documentation. You will hear it in standups, emails, and release notes.

What is the difference between release candidate and beta?

A beta version is earlier in the testing cycle and may have more bugs. A release candidate is closer to the final version and is expected to be very stable. Release candidates typically get only a final round of testing before the official release.

Why do teams use release candidates?

Release candidates reduce the risk of launching broken code. They allow teams to catch bugs in a controlled environment before customers are affected. This approach improves software quality and user trust.

Say it like this

✓We are cutting the first release candidate tomorrow

✓Let us push RC2 to staging for final validation

Real examples

in a standup

"We released RC1 yesterday, and the QA team has already found three critical bugs."

in a team meeting

Don't say this

Handle with care. Do not use as a verb. It is a noun describing a version, not an action. Avoid saying we release candidate something.

✕We will release candidate the app next week.

✓We will ship the release candidate next week.— Release candidate is a noun (a version), not a verb. You do not release candidate something; you release or ship a release candidate.

✕This is a release candidate feature.

✓This is a feature in the release candidate.— Release candidate describes a version of the entire software, not individual features. A feature is part of a release candidate, not the other way around.

✕We need to candidate this code before launch.

✓We need to include this code in the release candidate.— Do not shorten release candidate to candidate as a verb. Use the full term or say include in the release candidate.
