RC=Release Candidate, which means "release candidate", is not the final version, but the last version before the final version (RTM = Release To Manufacture). Broadly speaking, there are three traditional names for testing: alpha, beta, and gamma, which are used to identify the stage and scope of the test. alpha refers to closed beta, which is now called CB, which refers to the version tested internally by the development team or the limited user experience test version. Beta refers to a public beta, which is a test version that is open to all users. Then some modifications were made, and when it became an official release candidate, it was called gamma, and now it is called RC (Release Candidate).
PREVIEW is a preview version, and RC is a countdown to the release, which means that it is very close to the official version |
