-Alpha (during development)
-Beta (test version)
-Gamma (more advanced than beta version)
-Generally Available (GA) (Stable version)

MySQL naming rules

The MySQL naming mechanism uses a version number that consists of 3 numbers and a suffix. For example, a version number like Mysql-5.0.9-beta explains:
• The 1th number (5) is the major version number, which describes the file format. All Release 5 distributions have the same file format.
• The 2nd number (0) is the release level. The combination of the major version number and the release level constitutes the release sequence number.
• The 3rd number (9) is the version number of this release series, incremented with each new distribution. Usually you need the latest version (version) of the release that has been selected.
