Understand version numbers¶
A version number identifies the product release. The product contains the latest Generally Available (GA) features at the time of that release.
| 5.7.39 | -42. | 2 |
|---|---|---|
| Base version | Minor build version | Custom build |
Percona uses semantic version numbering, which follows the pattern of base version, minor build version, and an optional custom build. Percona assigns unique, non-negative integers in increasing order for each minor build release. The version number combines the base MySQL 5.7 version number, the minor build version, and the custom build version, if needed.
For example, the version numbers for Percona Server for MySQL 5.7.39-42.2 define the following information:
-
Base version - the leftmost numbers indicate MySQL 5.7 version used as a base. An increase in base version resets the minor build version to 0.
-
Minor build version - an internal number that increases by one every time Percona Server for MySQL is released.
-
Custom build version - an optional number assigned to custom builds used for bug fixes. The software features, unless they’re included in the bug fix, don’t change.
Percona Server for MySQL 5.7.18-14, 5.7.18-15, and 5.7.18-16 are multiple releases based on MySQL 5.7.18.
