Understand version numbers¶
A version number identifies the innovtion product release. The product contains the latest features, improvements, and bug fixes at the time of that release.
| {{vers}}.0 | -1 |
|---|---|
| Base version | Minor build version |
Percona uses semantic version numbering, which follows the pattern of base version and build version. Percona assigns unique, non-negative integers in increasing order for each version release. The version number combines the base MySQL {{vers}} version number and the minor build version.
The version numbers for Percona XtraBackup {{release}} define the following information:
-
Base version - the leftmost numbers indicate the MySQL {{vers}} version used as a base. An increase in base version resets the minor build version to 0.
-
Minor build version - an internal number that denotes the version of the software. A build version increases by one each time the Percona XtraBackup is released.
