# 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. | 8.0.29| -21 | |---|---| | Base version | Minor build version | Percona uses semantic version numbering, which follows the pattern of base version and minor build version. Percona assigns unique, non-negative integers in increasing order for each minor build release. The version number combines the base [MySQL 8.0](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/) version number and the minor build version. The version numbers for Percona Server for MySQL 8.0.29-21 define the following information: * Base version - the leftmost numbers indicate [MySQL 8.0](https://dev.mysql.com/doc/relnotes/mysql/8.0/en/) version used as a base. * Minor build version - an internal number that increases by one every time Percona Server for MySQL is released. Percona Server for MySQL 8.0.28-19 and 8.0.28-20 are both based on MySQL 8.0.28.
